davsco Posted April 11, 2020 Share Posted April 11, 2020 (edited) any small (short) but effective brakes out there (9mm pcc)? 1/2-36. i have a 3" jp on there now but it sort of ruins the whole sbr 8" barrel concept. thanks! Edited April 11, 2020 by davsco Link to comment
lonestardiver Posted April 11, 2020 Share Posted April 11, 2020 SilencerCo makes a single port muzzle brake that is also an ASR mount for their cans but not in that thread pitch.https://silencerco.com/asr-single-port-muzzle-brake.htmlThere are some others as well but most are 5.56 or .30 cal with a couple .338 tossed in for luck. Again the thread pitch is your main challenge. Link to comment
Chillywig Posted April 11, 2020 Share Posted April 11, 2020 Not sure how efficient any muzzle device is on a PCC other than making it a little louder but this one is short https://silencerco.com/asr-single-port-muzzle-brake.html Link to comment

egd5 Posted April 11, 2020 Share Posted April 11, 2020 I don't remember the thread pitch, but how about Taccom? Link to comment
ltdmstr Posted April 11, 2020 Share Posted April 11, 2020 SLR Rifleworks makes a couple different comps for 9mm with 1/2-36 thread. I have one of the linear comps that I'm going use on a 10" Faxon barrel. Just waiting for my JP upper/lower parts to arrive. Link to comment
StealthyBlagga Posted April 11, 2020 Share Posted April 11, 2020 With 9mm, the first port MAYBE has some effect, but subsequent ports probably not. Why not chop your existing JP brake to turn it into a single-port? Would be functional and unique. Link to comment
zzt Posted April 12, 2020 Share Posted April 12, 2020 The first thing I would ask is why you want one. If it is to make the report louder, or recoil a tad softer, go for it. If it is to make the gun shoot flatter, there are better ways to do that. I go for zero (or as close as possible) dot movement. My barrel is 5.5" long with a steel shroud taking it to 16.1". For some strange reason it is quite loud and no timer has a problem picking it up. While I was waiting for the gun to arrive, I read up on everyone's preferred PCC load for SCSA. There were the light bullet types, and those that preferred 124s. I shoot 115s in 9mm major and have thousands of them. So I started with them. I tried 950, 1000 and 1050fps. Yes, they were soft, but the dot rose and the second shot was slower. I tried 105gr. Softer and the dot still rose. I tried 124s at a variety of speeds from 1000fps up to factory. The dot still moved. I tried short stroking. No luck, plus it increased felt recoil. I went back to full length and continued testing. I ran out of testing ammo. My buddies were not ready to leave, so I decided to shoot up some of the factory 147 JHP @ 985fps ammo I use for SCSA when I run out of reloads. To my amazement, recoil, while harder, was straight back. At 50 yards I could put one bullet on top of the other as fast as I could pull the trigger. It just so happened that by buffer, bolt and spring assembly was 'tuned' for a 144PF load. So I ordered other springs. As soon as our ranges reopen I want to see if I can 'tune' the gun to shoot the 124 140PF loads I use for SCSA Open. That would be great, because that would be one less 9mm load to make. If not, I'll just use 147 factory. Link to comment
Norther Posted April 12, 2020 Share Posted April 12, 2020 I use the short Taccom brake on my 8”. I really like it. Unfortunately I don’t think they offer it anymore. Link to comment

lonestardiver Posted April 12, 2020 Share Posted April 12, 2020 Go onto eBay and search for 1/2-36 9mm and a whole mess of options appear. How effective? Not sure. But you have options. Link to comment
shred Posted April 12, 2020 Share Posted April 12, 2020 Easy way to tell if a comp is doing anything is clock it 90 degrees out of time (simple on an AR with peel washers), fire it and see what the dot does. Link to comment

If not, I'll just use 147 factory. That's what I go for in my straight blowback PCC's....I don't mind the kick as long as it's quick and the dot doesn't 'linger' as much. Softer/heavier loads tend to make the buffer linger more, which in turn moves the gun around it if you will. But if it cycles quickly back and then forward, there's less time for the dot to bounce up and back. So I use a Blitzkrieg buffer and a wave spring in back. That cushions the extreme ends of the buffer and bolt while still maintaining the speed of the cycle. I don't really imagine any sort of muzzle brake or comp doing much especially with a 14" barrel, except if the whole thing is really turned and it is the last, almost microscopic bit. Shorter barrel maybe, but the powder's pretty much burnt up at 8-10". Link to comment

TonytheTiger Posted April 13, 2020 Share Posted April 13, 2020 Hard to buy from a company that doesn't know the difference between a brake and a break. Link to comment

Yeah, I'm just bummed that I can no longer buy from Shooters Connection. Kind of like how I can't buy from a company that sells 6.5 Creedmore ammo even when the box they have pictured clearly says Creedmoor. Link to comment

Fortunately the airsoft muzzle brakes are some weird metric size like 14mm negative (Left hand thread), but I agree there are some really crappy fleabay brakes made out of chinesium that makes the airsoft stuff look hardcore!

jpeters11 Posted April 15, 2020 Share Posted April 15, 2020 Too busy shipping out orders lightning fast to proofread. Switched over to a Coda, if any of you want my old beat up one, it’s free, just pay for shipping Link to comment
