Oh, one more thing. My QC10 never ran 100% until I went 100% QC10. I have 1000 rounds of a variety of ammo with zero malfunctions now. I suspect you might do fine with the right combination of parts but working through getting mine to run was frustrating. IMO I think it's important to match the lower, bolt and barrel from the same mfr.

Ryan N started following Home defense AR pistol?

I did one but SBR'd it. 5.5" QC10 upper with a 8.5" Odin Works hand guard that allows for a little bit longer reach and also allowing a suppressor to go underneath it. I swap the suppressor over to a fake can so I can shoot matches with it. It's not the softest shooting PCC because its set up to run any ammo and not tuned to run a gammer load. Bolt weight installed, 308 carbine spring, Blitzkrieg hydraulic buffer. It can be a little gassy with the suppressor on but apparently that's something you gotta deal with when suppressed. FYI, I recently built a 4.5" AR22 pistol and

How often do you clean out all of the blow back crap out of the lower? I went a bit over 1K with a 243G and a scary situation happened. I pulled the trigger and there was a 1-2 second delay before the hammer released. It happened again and upon inspection I discovered that build up on the spring rods would hold back the hammer for a bit of time. Cleaning things up and all was GTG again. I have since moved the 243G over to another AR and swapped my PCC over to a CMC 9mm. 243G is a great trigger.... keep it clean.

I'm in Albertville Alabama. Let me know what all your interested ASAP, I have already had two other folks interested in different things.
Thanks,

I like a 50 yd zero for PCC because I want the up close hold overs to be the same as my other AR's. I have worked to create a habit of aiming 1.5" high at close targets with my 3gun AR and I want to do the same with my PCC AR.

Safety concern: if you experience "dead trigger" (hammer not releasing when trigger is pulled), be aware that once you pull the trigger the hammer could release at any moment. I recommend promptly unloading (while pointing in safe direction) and fully cleaning FCG components. I had an instance when I pressed the trigger and the hammer release a second or 1.5 seconds later. This happened about 1100-1200 rounds after I installed the 243G(with no cleaning inside lower). I now plan to remove FCG and clean every 700-800 rounds.

BTW, Optics Planet beat the Ebay price I saw of $279.99 by $5 so I got the 512C for $275+tax. <$300 delivered This is about the same price as any 510C I could find.

I ordered a 512C in red to replace my old trusty FF3.

I don't have either but plan to purchase the 510 or the 512. One disadvantage of the 512 I see is the mount. From what I've read, the 510c has a decent QD. The 512 doesn't.

I think your correct. I'm using the heavy springs which yield the lightest trigger pull. I have edited OP for clarification.

I shot Steel challenge today with PCC. Gun is a QC10 (upper, lower, barrel and BCG) and ran perfect with a variety of ammo but on the last 5 shots of the match I had to manually cycle the bolt before I could shoot. I looked into it a bit further when I got home discovered that the hammer wasn't releasing when I pull the trigger. As it turns out, there was buildup on the dual spring assembly which prevented the trigger from releasing. I removed everything, cleaned it and reinstalled it and all is good now. I'm using the heavy springs(which provide the lightest trigger pull). I wonder if the m

Thanks for sharing your thoughts guys.

Thanks for the input. I was mistaking about bolt/buffer weight. It's currently 17.7oz for buffer and bolt(weight removed). Adding the weight will take it to 21oz. Powders on hand are 231, WSF, HP-38, Clays and of course TG.
-
5.5" barrel, QC10 bolt(weight removed), JP 308 Carbine spring, BK hydraulic buffer, bolt/buffer mass is ~17.7 oz. Load is 3.0gr TG under 147gr Xtreme(I plan on running 4.3gr TG under 115gr). I wish I would have done a vid without the suppressor. Do you think the suppressor helps or hurts recoil impulse on a std AR 9mm? Based on what you see in the video, do you have any recommendations for me? Change in technique, stance, install bolt weight, load, etc?

That's fantastic.
