Drop in Bullpup kit for SCAR H

Just when you think you’ve seen it all, along comes this odd drop in lower receiver for the 7.62x51mm SCAR Heavy platform, turning it into a Bullpup. It didn’t gain much success, as the talk on the internet and the apparent release date was back in 2013, but it is an interesting concept to say the least. Currently I can only find 3 photos of it on various forums and all of them are for the SCAR H, none for the 5.56x45mm SCAR L. It appears to be a polymer lower, with the trigger group forward of the magazine, and forming a buttstock that contours with the edge of the end of the upper receiver. It looks like a black and a tan version were produced, but there are more pictures on the internet of the black version. It also appears to be using internal SCAR parts for the bolt release, and magazine release, presumably from the end users now discarded lower receiver. The pistol grip is using an AR attachment method, as one picture shows a Hogue like grip attached to it. Just from examining the rifle, the biggest problem would appear to be the cheekwield, which would be directly on the top picatinny rail. And the reciprocating charging handle, which would probably have to be moved to the opposite side of whatever dominant hand the shooter is using. I can imagine the pain one would feel of a charging handle slapping you in the cheek bone or nose from the sheer position of it.

The amount of gas coming out of the bolt slot can’t be at all comfortable. The biggest design hurdle here would have to be the trigger transfer bar, which I assume runs through a slot on the right side of the rifle, as all the pictures are showing it from the left side, and thus the better looking side if there were a bulging transfer bar slot. If any readers have any information on this design, I would be curious to know more about it.

And of course, we have the Airsoft version, where would we be without Airsoft….

    Is the distance between the shoulder and the grip not to long?

  • This is what I imagine a re-designed modern SA80 would look like. It has an interesting look to it but that gas port would give you some serious gunpowder breath.

    • Tom

      Personaly whilst I sort of like the aesthetics of the SA80 rifles I think a redesign would be a bit more complex than this. Step one place SA80 in the scrap heap step two buy a decent rifle.

    they took a beautiful thing . . . and made it ugly

    • Anomanom

      I’m not sure it’s possible to make a SCAR uglier.

      • ostiariusalpha

        I found it amusing that they maintained the aesthetic of the Ugg boot stock on the bullpup. I mean, why would you do that?

  • santi

    I’d buy the kit just for kicks. Think it looks great.

  • Suppressed

    Although I really like bullpups, I could not break up a scar to do this. It’d be like putting daytons on a 2016 corvette and making a lowrider out of it. I’m okay with it on a bullpup AK/ lowrider 64 Impala, but it seems out of place here.

  • Pedro

    Well, they do have a cover on the pic rails for cheek rest/weld and the top picture has the non recip bolt holder.

  • Rock or Something

    Just get a Kel-Tec RFB if you want a bullpup .308.

    • Jwedel1231

      Except without the ambi friendly ejection.

      • mig1nc

        MDRs have ambi friendly ejection. Like a shortened FS2000 ejection chute but different internally.

    • Hensley Beuron Garlington

      That’s like saying get a unicorn. I’ve only seen them online. Besides, we will soon have Desert Tech MDRs in .308.

  • BattleshipGrey

    I was really surprised when I saw this as I scrolled through the main TFB page, it was probably the last thing I expected to see today. It looks awesome! If I could afford a SCAR heavy, I’d probably make a point to afford this as well.

  • John Yossarian

    No – Just, NO! Never try to convert a standard layout rifle into a bullpup. Only bad things result.

  • mechamaster

    Creative idea indeed.. But of course it’s added trouble than benefits.

  • Llewellyn Franks

    Heya kids! I heard you like length of pull

  • Gorilla Biscuit

    So how did you loose your nose? “Forgot about the SCAR AREA.”

    • ozzallos .

      Is that like “Grip Zone?”

    • Micheal Unrau

      That’s a non reciprocating aftermarket charging handle

    • Ira

      Yeah you can see the housing for the non reciprocating charging handle mounted to the rail.

  • aka_mythos

    You talk about cheek weld right on top of where the reciprocating charging handle is; it appears the top most image the owner added a non-reciprocating handle.

    • May

      Also it’s worth keeping in mind that you could also just swap the stock handle to whatever side you’re not shooting from. Be a right pain to fire from that side, but if the SA80 and almost every AK bullpup are an indicator nobody cares about lefties.

  • Sianmink

    Seems to me they could have moved the trigger group back about 2 inches without hurting a thing. That LOP seems a tad excessive.

  • Ed

    Only time a SCAR didn’t look so crappy is with this kit.

  • USMC03Vet

    Way to ruin a perfectly good rifle.

  • Anonymoose

    No point in having a SCAR 16 in this, as it would still be inferior to purpose-built bullpups, and not enough gains over the AR (and with more weight).

  • 劉丁丁

    There’s SRU airsoft SCAR-L bullpup kit if you are interested.

  • Matt F.

    Haha, the kid in that airsoft video is from an airsoft club I helped train here. He’s quite an amazing fabricator of things considering his lack of Home Depot.
