Anyone playing with "PCC's"?

[Texas97]

The government is losing the court battles on bump stocks.
If they try to declare braces stocks and turn 40 million guns into untaxed SBRs it's going to go to court.

Maybe this is how we get the NFA struck down for the infringment it is. If a braced pistol is an SBR then they never should have allowed them to be approved by tech branch. If tech branch was wrong then they sure as shit shouldn't have let this go on this long.
Bump stocks weren't owned by that many people Braces are owned by millions of people.

i dont think how many people own them is going to matter at all to the courts. bump stocks should lose in court because they are not a machine gun. period. The atf didnt amend the definition of a machine gun in the code, they are just saying these are machine guns. it should be struck down hard.

as to braces, i think you are stretching hard about what tech branch is wrong about and what it isnt. remember, their opinion letters are not law. The ATF has a history of flip-flopping on everything they have ever done. its not a matter of if, its when.

i dont think the argument of "a lot of people have them" is going to fly when they decide if they are actually a stock, or not. and like i said before, you remove the brace, and its no longer an SBR. The gun is then still a pistol and your brace is not "illegal" it just becomes a stock.

in no scenario can i see the NFA being struck down because ATF tech branch changed their minds on a determination letter. lets live in the real world, not fantasy land.

I didn't really expound on it, I'm not saying that the atf will out of the goodness of their cold dead black dog shooting hearts just give up on sbr laws. Sb tactical needs to get off their asses and challenge the nfa. It has never been properly challenged at the Supreme Court level.

Right now there are conflicting rulings on bump stocks in different federal districts. It needs to be heard by the Supreme Court to smack down the atf for trying to write law. A bump stock is not and never will be a machine gun.

why would they, their entire million dollar business is based on the braces being a loophole to bypass the nfa

For all the disabled vets they claim need and use their braces.

My Foxtrot Mike 9mm. It was originally a 7 inch barrel with flash can. I needed something longer so I could mount my Omega 36M. I ended up with a Faxon 10.5 inch barrel and an ASR flash hider to mount the Omega 36. I have not filed a form 1 yet so currently a pistol. I have an SBA3 brace I use but it’s on another gun.

What buffer and spring are you using?

I just got the same upper (or real similar). Instructions are pretty specific, but I'm not finding a lot of options that meet their criteria. Are they just trying to make me buy more FM products?

The correct buffer and recoil spring are REQUIRED to ensure reliable operation of a blowback design.

The buffer should be at least 6oz in weight and MUST be less than 3.8" long.

A buffer that is longer than 3.8" will not produce enough dwell time, to allow for reliable reset of the trigger.

The ONLY recoil spring we recommend is a .308 carbine spring.

FM Products will not be able to troubleshoot any problems that result from using improper buffers and recoil springs, and cannot warranty any damage that occurs.

The use of any "short stroke" recoil system, plastic buffers, or other "competition" widgets can result in burst fire and may VOID the lifetime warranty of any FM Product.

They also "STRONGLY" recommend using a FCG designed for blowback PCCs, I guess I didn't know that was a thing. They go on to discourage standard 5.56 drop-in AR triggers as "they can result in burst fire due to the shortened dwell time."

5.56 Carbine spring and H3 buffer. My milspec fcg with lighter springs works just fine. 3k+ rounds.

Thanks!

In researching I've read several folks claiming the .308 spring and 3.8" proprietary buffer is just FM trying to sell more parts. It's on the internet so it's true.

How's that side charging handle once assembled? I don't have the lower yet. Attempting to manipulated it with a loose BCG in a detached upper with no buffer spring, didn't inspire a lot of confidence. It feels very plasticy, and while FM slathered it in oil, it isn't what I'd call smooth. Hopefully once assembled and a few rounds to break it in, it'll be better.

I’ve tried the .308 spring. It resulted in failure to feed. It was trying to shove the bullet into the chamber too soon. I know I could probably use a heavier buffer but the H3 works just fine. I have a couple dollars in quarters in the tube to shorten the buffer stroke. The only reason I haven’t gotten a heavier buffer is because it runs 100% suppressed or unsuppressed. Charging handle is fine. I plan on swapping it out for the paratrooper charging handle. It folds forward.

strikes me as odd, people are usually searching for additional bolt travel
like that way expensive surefire bolt carrier, part of its special sauce is a longer bolt overtravel

9mm ARs like to snap off the bolt catch. Limiting buffer stroke helps prevent it. The bolt catch on my Foxtrot Mike is beefier than a normal milspec catch.

Oh that makes a lot of sense, hold open is a pretty weak little guy and the 9mm ARs do got some retarded bolt velocity

I've actually experienced this with mine. Now I can't remember who made the trigger .
I think it was this

RISE ARMAMENT RA-140​

But really can't remember.
