Purple Patrick 638 Posted November 15, 2016 What is everyone running? I'm looking at finally getting my sub2k soon and need to pin something on the threads. I'd prefer to get some kind of muzzle device (strictly for looks) over just pinning the black thread protector. Has anyone tried pinning one of the "custom" thread protectors? How bad does the pin/weld mess it up? For 1/2x28 thread pitch this signature exceeds the 15 character capacity count Quote Share this post Link to post Share on other sites
Bt Doctur 188 Posted November 15, 2016 why do you think a threaded barrel need pinning? Isn`t a one and half inch bore quite large very close to 40mm grenade launcher Quote Share this post Link to post Share on other sites
JT Custom Guns 956 Posted November 15, 2016 We use CNC Warrior Knurled Compensators on the AR-9's and they seem to work well, look good & are very well made. The 9mm AR's are 1/2-36 They do offer a 1/2-28 version for $30.00 along wit ha few other variatons............... Quote Share this post Link to post Share on other sites
JT Custom Guns 956 Posted November 15, 2016 why do you think a threaded barrel need pinning? Isn`t a one and half inch bore quite large Because the gun he asked about is a Semi-Auto with a pistol grip. The thread pitch is 1/2 - 28 (not 1.5"-28) Quote Share this post Link to post Share on other sites

I fixed it We use CNC Warrior Knurled Compensators on the AR-9's and they seem to work well, look good & are very well made.

I'm surprised they went with the common pistol/ar thread and not the more popular 9mm ar thread. this signature exceeds the 15 character capacity count Quote Share this post Link to post Share on other sites
mipafox 438 Posted December 8, 2016 Just for fun, check out Carlson Comps. Their flash enhancers seem cool, just make sure you get something with a hole big enough for 9mm. If you see something you like, give him a call and he may modify it. He's on UZITalk. If you want to get weird, TROS will adapt that to any thread size you want. If it is not on their website, call them and they will do it. They sell a couple comps as well. Quote Share this post Link to post Share on other sites
