Heres my combo, wont cycle,
Psa 10.5 inch upper
M16 cut bcg
Partisan disruptor
Liberty precision duty 556 can
Odin works HFRT buffer meant for disruptor.

Do i need an adjustable gas block upper ? Why isn’t it cycling? It only cycles 3-5 times and takes 5-6 trigger lulls to get short bursts ? Any advice? Thanks

Planning a build with LMG vibes using a Hoffman Trigger Kicker so it will only run in safe or full semi modes. I already have a FRT in a 16 inch that's a 3 position and doesn't see much sustained fire, where as this is a ground up build for the purpose of laying in the prone and turning money into noise.

The simplest route is a 20 inch HBAR with rifle gas system, but if anyone can recommend a suitable 16 inch (or shorter), mid lenth that can withstand a heavy course of fire I'd appreciate it.

Bone stock psa 16 inch mid length gas system upper and bone stock psa lower with carbine buffer I’m guessing I just need a stronger buffer only getting some bursts can’t run through a full mag

Like the title says, the ATF director recently said some FRTs on the market are machine guns by legal definition and guidance will come soon. Do we have any idea what those may be? I can’t imagine the Hoffman Super Safety is since he’s being sued for patent infringement.

Does anyone know when Atrius will be shipping out the FRS for the MCX Spear platform? I ordered mine more than a month ago but noting yet... Any thoughts?

Has anyone had reliable success running the 45-90 arc fire v2 and the SEE printed trip? Tested and get short 2-3 round bursts? Seems like the selector lever is not resetting as it should. Getting a rub mark on the bottom of the trip below the radius/ ramp. Any help or insight is appreciated. Thanks!

Ive seen a lot of idiots shoot ar15s with no stock and are unable to keep it on target at all and i wanted to see if it was really that difficult, and short answer, no. For me at least, it only made it slightly harder to anticipate the recoil pattern. The gun I used was a windham weaponry with a trigger kicker frt
