Thank you both. When I emailed with Frank at compasslake engineering, he stated that since they will drill the gas port, that they will drill the +2 at no extra charge. I’m good with that. I guess now I need to determine size of hole, gas block, correct gas tube and buffer system. All my ar15’s run with the jp silent capture.
when I was looking at compass’s website, the do also offer a head spaced bcg, it’s an A.P. bcg. Think this will be okay or purchase the jp full mass and send in to have configured with my barrel.
Now, if I go to Kreiger website, they do headspace a jp bolt to the barrel, and that acted like I was nuts when I asked about the +2 gas port. When you order your barrel from them, they pretty much want you to send in your upper to headspace barrel and bolt and will fit your muzzle device also.
i did NOT get into this thinking i was going to build on the cheap, use cheap parts. I didn’t do that when building engines, won’t do it building guns. I sure didn’t start this project to save money, kinda like buying a truck for gas mileage.
so order a Armalite gas tube? But first I would need to measure the length from the port to gas key?
Same with buffer system. Also order that from Armalite? Any recommendations on part numbers. I’m running A.P. M( set up.
again, thank you all
