New Open .308 Receiver Set from F-1 Firearms

F-1 Firearms is living up to their name releasing their latest go-fast parts, this time for the .308 platform. The new BDR-10-3G billet receiver set is designed for the shooter were speed and looks trump practicality (or where speed and looks are their own kind of practicality).

While the receiver set is unique to itself, meaning those with their own upper or lower will need to find a match, the set is set up to use common .308 parts. Specifically, the set is set up for DPMS LR-308 components (Gen 1) in the DPMS “high” pattern for the handguards. The lower accepts common AR components and the magazine well is designed for the common MagPul / SR-25 pattern of magazine. The magwell is further beveled 60 degrees for easy magazine insertion.


For tight fitment, tensioning and trigger adjustment screws are included. Construction is out of billet aluminum (but no call out on if its the higher-grade 7075, though its 5.56 cousin states it) with Type III, Class 2 hard anodizing. Other features include an over-sized trigger guard and finger grooves on the front of the magazine well.

Black is standard at a retail price of $625 for the set. Anodized colors are also available for an additional $50 and up to a two month wait. 

Interestingly, the billet set includes a provision for a dust cover. Why it has that for being completely cut open is an interesting choice…

  • Dirt will love it!

  • Vhyrus

    Should be easy to clean. You don’t even need to crack it open.

    • GaryOlson

      Just throw it in the dishwasher along with your SR25 mags — and don’t forget the spot remover or everyone will diss your spotted receiver.

  • Kyle

    That looks very unpleasant to fire.

  • Martin Grønsdal

    The dust cover is in case if you don’t want dust to enter the gun exactly there.

  • Suppressed

    I hope they make a version of this receiver that accepts Magpul GL9 mags so I can use my Apex J-plate mag base pads with it.

      I’ve got a bridge for sale if you’re interested.

  • Tyler McCommon

    Just why….

  • Giolli Joker

    Last year when we saw something like this it was April Fool’s joke… now it’s real?!?

  • USMC03Vet

    I dunno about this, need to see a wheel barrel full of mud test first.

    • Hensley Beuron Garlington

      Be awesome if the design is so open it just blows all the debris out (not likely). Patent it as “pass through cleaning technology”. Simply bump and blow on it (LOL) to knock out loose dirt, wash with water, air dry, dip in oil, done! Repeat as necessary! No more take down just to clean your rifle!

    • Josh

      I think it would be very interesting to see someone actually try a mud/sand test on this just to see how well/bad it does. Can someone with deeper pockets than me get on that?

      • Don

        Well theoretically, it would probably do better than a standard receiver set. After all, what kills the weapon in that kind of a torture test is the sand/mud getting trapped between the receiver and the moving parts. With a skeletonized receiver set, there is less material for the grit to get trapped between. Just a guess though…

    brings new meaning to full on tactical retardation

    • Don

      Obviously you don’t follow the shooting sports too closely… This was never meant to be used for tactical purposes, they cater to the speed/competitive shooter world.

      • 48conkli

        What purpose does it serve besides looks. So in a competition it is desired to have open wholes in your gun letting in dirt and debris, hell you could even get a small pebble through that. and it could cause massive failure in the middle of the competition and cost you the match. The only credibility it would lend is being potentially lighter by a small margin.

        • Don

          Every single competitive sport does the same thing. A tenth of an ounce here or there could mean the difference between winning or coming in second. My .458 Socom doesn’t have a dust cover so my bolt is exposed to the elements and I never have any issues. You could get an FTE in a fully enclosed upper during a competition that could cause the same devastation. You are in for a long boring life if you let the “What ifs…” Rule your world…

  • Greg Anderson

    First paragraph, second sentence. “…shooter w(h)ere speed and looks trump…”

  • Evan

    This has got to be a belated April Fools joke. I saw basically the same joke last year. Nobody would buy something this stupid.

  • DIR911911 .

    no numbers on the weight vs original? it would have to be pretty light for me to spend $$$

    • Don

      If you clicked on the link you would have seen the weight of this set and their normal set… 1.48lbs vs 1.60lbs

  • cons2p8ted

    Might as well only wear a thong to combat in Iraq so that your ass crack can empathize..

  • Patrick Karmel Shamsuddoha


    • Christian Hedegaard-Schou

      It’s a mistake. Those aren’t holes for mounting a dust cover, those are just more speed holes 🙂

  • Vitor Roma

    By the way, I imagine that a gun with this receiver will feel like Auschwitz when running supressed.

  • DetroitMan

    Last time I checked, making a .308 lighter doesn’t work out so well when you actually start shooting. There’s this weird effect where weight helps to mitigate recoil (crazy, I know!). But if you’re a mall ninja who wants maximum tacti-cool, your .308 has arrived.

    • Don

      Hmmmmm… I wonder what compensators / brakes and adjustable gas blocks are for? (He says as he scratches his head wondering why someone would make such a dumbfounded statement) I have a light weight .308 AR and it recoils no more than my comped .556. I’ve got everything on mine from a light weight Proof Research carbon fiber barrel to the JP Rifles light weight BCG and it’s a joy to shot. You know, they do make this thing called a .22 rifle for people who whine about too much recoil…
