Project Spark Plug: PWS Summit Straight Pull 22LR – Part 1

Every shooter has what they refer to as their list of “grail guns”. That is, firearms they would easily order up if they had the resources to buy whatever they wanted (#hipointcarbine). On the other end of the line are the “everyday” type guns that steep themselves in utility and are fairly obtainable for the masses, like a Glock 19 for example (#everyoneshouldownone). Somewhere in the middle are a collection of guns that are realistically in reach with a little bit of saving and/or searching. For me, one of these guns is the Primary Weapons Systems (PWS) Summit straight pull 22LR 10/22 style receiver.

Sure, it’s not a super-sexy, spiced up race gun or a tacticool AR, but maybe I’m showing my age – a super quiet platform that accepts the mountain of 10/22 accessories on the market is just what I need.

PWS Summit 22LR

PWS discontinued the Summit line a few years back to make way for additional production lines on their flagship centerfire rifles. So, if you are like me and have been on the hunt for a Summit, you are out of luck.

Ok, that was just mean. A few weeks ago I emailed PWS customer service about the Summit availability and future plans. Luckily, they now consider the unique rimfire receiver is in “limited release” with only a few dealers buying up nearly all of the production well in advance. PWS referred me to The Armory LLC for a possible pre-order avenue and I nearly burned a hole in my keyboard typing up an email to them.

As luck would have it, The Armory didn’t have a pre-order list, they actually have a few of the Summit receivers in stock. After a long talk with Thad, the owner who happens to be an NFA nerd/nut like myself, I jumped on one and had it land at my dealer a few days later. Boom.

So if you are looking to get in on the game, I’d give The Armory a phone call (they aren’t listed for sale on their website at the moment). In the years that I have been looking, they are the the only ones I have found who have Summit’s in stock. And yes, no tricks, there are a few more.

So, what do I have planned for my long term “Spark Plug” project? That’s where you guys come in. I’m looking for build input from our readership. I’m leaning towards a small compact Charger build with an integrally suppressed barrel, wood/laminate stock and variable power pistol optic. However, I am open to any ideas you all have. Shoot me an email, leave a comment or follow us on social media to get a message my way.


Summit

The Summit action is a straight-pull, or toggle bolt action. It features a 20 MOA base Picatinny rail machined into the receiver allowing optics to be mounted quickly and securely.

Dual extractors in the Summit Action’s bolt increase system reliability.

  • Steve

    I hope the one you got was a version 2 model – given the price of these receivers, the original issues they had with headspace and such were pretty lousy.

  • Giolli Joker

    An American SV-99?

    • Steve

      The secret sauce in the SV-99 is the unobtainium stock – the receiver is easy enough to get in the USA if you’ve got the cash.

      • Giolli Joker

        You mean the 7-2-ko mentioned in a comment below?
        Having a wooden/laminate stock made by a stock maker should not be that hard, maybe a tad bit expensive.

        • Steve

          Having a stock made isn’t the problem. Having THE stock made is. The SV-99 stock has a heavy-duty take-down assembly behind the receiver, a Parker-Hale spigot, rear adjustable features, etc. By the time you’ve added all these features into a 10/22 stock, you’d have a pretty expensive rifle.

  • Jeffrey Smith

    Still confused as to what is special about this… how does it differ from a beefed up 10/22?

    • Tony

      It is a straight pull, toggle style action instead of being a semi-auto.

    • Giolli Joker

      Not semi-auto = quiet.

      • Sardo Numspa

        My Tacsol X-ring is noticeably quieter than a PWS .

    • JSmath

      It’s a toggle action, ie not semi automatic. Since the action isn’t cycled by firing energy, muzzle energy will be increased versus identical barrels.

      Additionally, less noise is produced by firing while suppressed.

      Mostly it’s for gimmicky cool factor.

      • Pete – TFB Writer

        I’m not sure it’s gimmicky or for “cool factor”.

        I wanted a bolt style gun that could accept 10/22 barrels and parts. Like a Gemtech Mist for example.

        • JSmath

          I may be biased in that regard, because I myself desire toggle bolt guns in part for the gimmicky cool factor.

          As far as specifically the 10/22 and suppressing it, it is absolutely a gimmick to use a manual action, IMO, because with the same grip you’d use to hold and cycle a toggle bolt, you can pinch the charging handle of a regular 10/22 and get the same quiet functionality out of it. Takes all of the suggestion of a breeze to keep the thing closed (albeit not completely locked).

        • Dr. Longfellow Buchenrad

          It would be cool if there was a way to manually lock and unlock the action so it could cycle like a normal 10/22 or be manually locked to be operated manually only. Kind of like the M14 gas shut off but obviously accomplished by other means.

          • Giolli Joker

            There is already such a thing for the 10/22, I don’t remember who makes it, saw it tested on a suppressor testing website.

        • Sardo Numspa

          The Thompson Operative is fantastic and you only have to unscrew the baffle from the end of the barrel instead of sliding the whole barrel shroud off the mist .

      • Duray

        I believe you’re mistaken about muzzle energy being measurably increased in a locked breech mechanism.

        • JSmath

          Fair point, though I didn’t claim measurable.

          • DIR911911 .

            how else would you know it increased?

          • Giolli Joker

            Physics. But yeah, no real world advantage.

          • JSmath

            Because it is still plainly observable when tested. Even with examples of elusive 22LR behaviors, some minor increase in velocity is observed. Usually some 20-30 fps or 3-4% of difference. Not quite worth it, but the same could be and is frequently said about increasing barrel length on AR15s past 16″ – Zealots will just jump at the opportunity to file such numbers under immeasurable – referencing talk of standard deviation and the like, but if integer values are accepted as measurable for chronographs, it makes no sense to throw away double digits.

            Usually the least amount of to no zero difference is observed when extremely non-rigorous approaches are taken to locking the bolt closed – such as using duct tape to hold a bolt closed (which can and will slip and stretch) – really fails to accurately portray the mechanics between the two approaches.

            In the realm of competition, 3-4% improvements (especially in several places) are the driving factors that very often separate competitors and their respective equipment.

  • Komrad

    if you’re going to go the suppressed route, definitely get a twist rate appropriate for 60gr Aguila SSS ammo

    • JumpIf NotZero

      Yay for a special barrel that only runs one rare and albeit quiet otherwise poorly performing ammo!

      • Christian Hedegaard-Schou

        That’s not how twist rates work.

  • Lew Siffer

    I have heard of a similar type action, just like this except there is a sort of latch so you have to move the handle up slightly before pulling it to the rear, and then you follow it forward with a downward motion to lock it in place before firing again.

    • iksnilol

      That’s a stupid action. Up and then back? Preposterous.

    • Shankbone

      And the Ruger 77/22 has all the fun accessories available like its relative, the 10/22. (I know that’s a Ruger American in the pic…with no locking bolt.)

    • tazman66gt

      I’ve been able to move that thing that goes up and back with my thumb. Not really that hard to cycle that way.

  • Scott Willbanks

    I have one of these that I decided to install a Hailey AeGIS (Adjustable Gas Integrally Suppressed) Barrel. It is currently with Hailey for proper calibration and installation, but I’m more than excited about the possibilities

    • Pete – TFB Writer

      Awesome. Talk to me about the adjustable gas.

      • ozzallos .

        That sweet, sexy gas is so adjustable you’ll have sultry dreams about it. Just how adjustable is this gas? Like a gymnast– Adjustable, flexible, anything you want it to be and more.

    • iksnilol

      Is ther AeGIS smooth like Hailey’s skin ?

  • Sianmink

    Totally suppressed charger. Set it up for subsonic heavies, maybe source an integrally suppressed barrel of about 9″, or a threaded 5.5″ bull barrel, it would be sweet.

    • Pete – TFB Writer

      Exactly this.

      • Flounder

        Why a big awkward pistol that you will probably scope?

        Why not make a rifle? For 1-2 pounds more you get a longer barrel and a stock and you can use the scope muuuccchhhh more easily!

    • Sardo Numspa

      My buddy had a PWS summit with a Thompson Machine Operative integral suppressed barrel the quietest thing you ever heard ….that is until he ran it heads up against my Tacsol X-ring with a Thompson Operative and mine was significantly more quite so he sold it and got an X-ring . The one great thing about about the Summit is the ability to cycle any ammo but its a surprisingly louder action .

  • Graham Baates

    We shot one of Zastava’s toggle-bolt .22s when we visited them in 2015, but I guess that model was never imported to the US.

  • thedonn007

    So, ballpark, how much are we talking for the reciever?

    • Pete – TFB Writer

      $599 for an adjustable match triggered receiver. Sorry forgot to put that in the story.

      • KSUJedi

        Looks like $625 on their website, got a little discount action… 🙂 Assuming its coming with the same trigger you received, not a lot of details on the website, might have to shoot them a text to confirm. Looked into these awhile back but had also found them to be discontinued/unobtanium, your darn post may have just made this a $625 more expensive day for me… Thanks!

  • Nikolaos Theodoratos

    I have one and it’s a love hate relationship. The first receiver that PWS sent me, the barrel hole was so large that a barrel could not be screwed down. It just wobbled around with the block tight up against it. It went back and i got a tight one. I put a Feddersen barrel on it and it acted like a shotgun, would not hold group for nothing. I contacted Feddersen thinking it was the barrel but agreed with Fred to try several different brands. Eventually it just quit shooting. Would not fire anything! I called Fred back because he was so helpful with his barrel and he suggested I check the headspace. I could fit .075 worth of shims between the bolt and the barrel with no barrel shims on the receiver. Number 2 went back and they changed the links on it. I shot it a few times when I got it back and noticed that the toggles are getting loose again. I gave up and now it sits in a gun safe. I had to pay for one way shipping both times also even though the rifle was defective. When i complained PWS sent me a free hat. They will never see another penny from me. I hope some day to make it work but I’m not holding my breath!

  • Shankbone

    Would a Browning T-Bolt accomplish the same results with a tang safety, barrel, and stock for $550? (Micro Midas pictured.) https://uploads.disquscdn.com/images/e4f9668937d8fa87fe73ffb77c5a9f783cfd7784b01e351a13ce13a61fc401ad.png

    • noob

      Got rails?

      • Edeco

        The fettle of Brownings seems to be stuck in the late 1980’s. Gold triggers, smh.

        • Shankbone

          “Fettle”? 1800’s, is that you?

    • Shankbone

      Someone asked about rails for the T-Bolt and they are blocked now. Anyways, there are at least two different Picatinny rails for the T-Bolt, EGW and Recknagel.

  • Gary Kirk

    Ruger M77/22.. Problem solved..

    Mine’s rocking a heavy barrel, A2 birdcage, and my Gmt Halo.. 🙂

  • Anomanom

    Am i mistaken or didn’t someone do this a few years ago called the Zip 22?

    • iksnilol

      No… the Zip…. we don’t talk about it.

  • DADPOOL

    the 7-2-ko is a much better gun in just about all aspects. The action is much smoother. mine would,I’m not kidding, shoot right along side my anschutz 54. and the trigger is better than anything short of a KIDD. The 7-2-ko is getting pricy but by the time you build one of these pws’ up you’ll have comparable money in it. I don’t know why anyone would buy the pws and I really like straight pulls.

    • Giolli Joker

      That would be the civilian SV-99?

      • iksnilol

        Kinda… the SV-99 is a civilian gun, it just got militarized.

        So it is more correct to say the SV-99 is the militarized 7-2-ko instead of saying the 7-2-ko is the civilian SV-99.

  • Blake

    See if it’ll fit into that P90-clone bullpup 10/22 stock 🙂

  • mazkact

    With firearms manufactures seeking new customers lately I can see a return to toggle locked .22 rifles. There once were many nice ones on the market that were substantially less expensive than this or Anschutz Fortner style actions. I wish the Baikal/Izmash Biathlon basic rifles to be imported again. All things being equal I have to believe that a locked breech rifle will shoot better than a blow back one and with the toggle lock it is easier for most people to maintain sight picture than with a bolt gun.

  • Jon Kann

    I know that a lot of people have had issues with the platform. I have one with a 21″ stainless Lilja barrel and it shoots lights out with ammo it likes (Wolf MT, Eley SSHP). I got a 5 shot 50 yard .19″ group from the bench with the Wolf. I love mine.
    If i were doing another one or a different set up i would go with a bit of a lighter barrel for a walking around squirrel laser.

  • Tom Engel

    Brownells have the Summit barrels in stock…..Summit action, barrel and Hogue stock. Warlock II and she is Hollywood quiet….Ruger American Rimfire will have a new home as soon as my Summit gets zeroed

  • Triplanetary

    It looks a little like a $275 SPA-17-22. Of course there are no accessories and replacement mags are $40 and are some of the flimsiest , worst mags I have ever seen.

  • phauxtoe

    Straight Pulls are Cool,
    Anschutz are Cool!
