Drop in your AR lower and choice of bufferless upper.

Why didn't they just make it a lower receiver, rather than adapt it to Rube Goldberg up to your existing AR lower receiver?

The micro version really needs some sort of P90 style integral foregrip.

Hmmm. Seems short enough that the back end of it could nestle into the inside crook of the elbow by design and not the shoulder!
Similar to the Bushmaster pistol of years gone by. Not sure if the Automatic Transmission Fluid guys would agree - but nothing they ssy is consistent for long anyway. |

Its an interesting concept, and the drop-in nature caters to people who might already have an SBR'ed lower. It really needs a kind of integrated / angled grip in the front like the Desert Tech MDRX Micron.
I think this will be 100% price dependent. If it is on the cheaper side, I could see it selling well. If it is like ridiculously expensive then it will be a short-lived gimmick like pretty much every other bullpup conversion kit that has come and gone. And just so I can drag out an old meme from the Stribog bullpup thread:

It would benefit the sales of the chassis, and would likely sell as a standalone for FM15 uppers as well.

With the brace “ruling” and the amnesty stamp, I’d imagine the market is primed for this. The FM15 may not be super popular, but just imagine all BRN180 and JAKL pistols that were out there. |

That’s an 11.25” upper. This is definitely growing on me.
The FM uppers can also use standard AR barrels with minor modification to the barrel or by opening up the oe barrel nut, so running other calibers is possible.

It also sounds like they have plans for larger ID FM15 handguards in the works as well. Tuck a suppressor on a shorty while adding more railestate. |

That is very appealing.
As far as the compatible bufferless uppers, is there any consensus of one being superior to the others? I have a spare lower that I'd like to use for an SBR with this. |

So I would have to provide the bufferless upper, a bolt catch setup, and a stripped lower?
Does the stripped lower have to be a pistol to go into the pistol cfg? I was looking at the FM15 gen 2 maybe... |

You just can't build it as a rifle first and then decide it's a pistol - it needs to be either virgin stripped state (heh) or it needs to have been built out as a pistol first. Yeah, dumb, but...ATF gonna ATF. |

I'm torn between a 300blk or a 9mm upper. I have an SBR lower that's sitting without a mate at the moment.
And if I do go with a 300, I don't know weather I want the JAKL, BRN, or if I want to convert a FM-15. At least I've got a few months to figure it out.

The handguard overhangs just enough for the compact grip/handstop. Only problem is it’s a BRN upper. I definitely want a FM15, but the 9” FM15 is just a little too short and looks funky. I just purchased one of the 11.25” FM-15 uppers. I’m going to cut the hand guard down and swap in a 10” or 10.5” 300blk barrel. I’d love to use the BA 10.3” Hanson barrel, but I think the taper after the gas block on their pistol gas barrels is too long to work with the FM15 barrel nut. Or I do the same thing, but use the .223 Wylde 10.3” BA Hanson barrel. My current go to SBR is an 8” suppressed 5.56. It would make more sense to keep the Triad upper in 5.56 for practical ballistic reasons as I need to have a 10”+ barrel on it anyway, and just change my other SBR over to 300blk. But a 300blk the size of a P90 is also cool. Ugh! |

$700? unfortunate pricing. your gun will end up being the same cost of a factory bullpup, and that's if you use budget parts.
a duty grade AR with this kit will cost alot more than most bullpups. this is a two piece chassis. aluminum for the trigger & grip, and plastic for the part on the lower receiver. kind of odd honestly. they are connected at the thinnest part of the chassis by a screw. durability needs to be tested. this thing seems overly complex for what it is. the SCY bullpup chassis is one piece and $200 cheaper. bascially the only advantage the A3 offers over the SCY is it has a built in buttpad. that's not worth $200. if the thing was completely polymer with a thumbhole grip, it would be way stronger. compare this to a complete milspec kp15 lower priced at $200. they're both injection molded, and the triad doesn't have a buffer system. so how did they end up with something 3.5x more expensive? MAYBE $300 would be fair. i think this is just a monopoly situation. there's only 1 altarnative, and it's a bit more jank. |
