Quoted: I think with a 16" upper it needs a stock spacer to hit the legal Title 1 length? View Quote View All Quotes View All Quotes Quoted: Quoted: What’s the OAL with a 16” upper? This could be pretty fun with my .22. I think with a 16" upper it needs a stock spacer to hit the legal Title 1 length? That was my thought |

How are mag changes?
I think that's the biggest thing keeping me from doing a bullpup, but I've wanted a brn180 and I've also wanted a bullpup. Best of both worlds? Compromises? How's the trigger? It's cool af. Didn't know that lower existed. |

Quoted: Will work fine w/ a regular AR upper. Remove upper, load the chamber, cock hammer, put safety on, install upper. Safety off. Fire. Remove upper, eject the round, load next round, cock hammer, put safety on, install upper.

What I did notice is that you're pretty much huffing exhaust gasses with your face right there. |

An AR 22 isn't a normal AR upper, but yes, it will work quite well with this bullpup system. |

OST.. got to build me one.. bet it would be a hoot with a FRT in it.

Quoted: No way would I have my hand that close to the muzzle of a short barrel rifle round. Especially when you have no way to properly hold the gun when firing (unless you only have one hand). Wear a glove and send pictures of your future ER visit. View Quote Are you unaware of the ove glove? |

Especially when you have no way to properly hold the gun when firing (unless you only have one hand). Wear a glove and send pictures of your future ER visit. Are you unaware of the ove glove? That, and this is little different than thr P90, which doesn't seem to cause a lot of problems. That, and OP apparently intends to run it supressed, which pretty much takes care of that. That said, I don't think I would have gone any shorter than 10.5" personally. Once you go as short as he did, the difference between 5.56 and just way milder 5.7 or .22 magnum, start getting closer. To me, ideal SBR bullpup is a 12" 6.5 Grendel. That is a combination of the most optimized small Frame round, with the most optimized small barrel length for it (12" Grendel ballistics are tidy), in the most size optimized gun configuration of a bullpup. That's a package you deliver 1000 ft-lb at 100 yards, accurately shoot out to 600+ yards, in a tiny small frame package. That's what I want. But this particular model approach apparently requires an exotic non-standard gas system that you have to cobble together, as a conventional DI won't make any sense in it. |

Anybody tried the Reap Scy system? Can use a standard upper, or a bufferless upper, but requires and MLOK or KEYMOD rail handguard. Looks interesting, but two things, the LOP looks crazy long and can't tell if the FCG is fully enclosed within the clamshell, or open to the slots in the rail, where heat from the barrel and contaminants could get in.

They get goofy and stupid. So you have to have some kind of exotic system with a completely different operating system that has very little length extending back. Which can be done, but often expensive, goofy, and not all work right. In the end, these tend not to be the way to go, vs just buying a purpose built bullpup. It would be better if they sold a complete conversion package, but that site's website is very difficult to navigate, and there's no "Click Here For Complete Conversaion Package" option, that includes whatever gas, bolt, and recoil system forced onto the AR platform they need, to make it work. But OP's is interesting because he was willing to cobble all of that together himself along with some customization, to make it all become that package - which is pretty neat. |

Next to a 5” AR pistol and an 11.25” SBR.

An intact FM-15 11.25” 5.56 with stock folded is only 21.25” long with flash hider. I would expect the bull pup version balances better (especially suppressed) but adds weight overall. I think with an 11 oz folding stock, 4 oz red dot, and empty 20 round mag I weighed the conventional configuration at 6.25 lbs. What do these two bull pups weigh without ammo weight?

I mean, the Iranians got an AR based bullpup to work, can't be that hard, man. I don’t think the Foxtrot Mike buffer less operating arrangement is that exotic. The Stoner style bolt keeps carrier tilt forces minimal and the upper receiver as guide coupled with the nested recoil springs & guide rod telescope into both the gas key and cocking tube make the off axis recoil spring seem positive in function. Where I would have a concern is suppressed ejection port gas and port pop over something like a Keltec RDB, as well as safety in the event of a kaboom. |

Feed it .300 Blackout, the side of the receiver gonna bop you in the nose. AR failure mechanism is well known - and relatively safe.
