So I've found a bunch of spare parts that I've accumulated, including a ban-style 20" HBAR barrel of uncertain lineage. I'm going to cut the barrel down to 11" for an AR pistol. I know that I should use the carbine gas system, which I believe puts the gas hole at 7.8" from the bolt face.
So, how big should I drill the gas hole? I've seen lots of opinions, but no solid answers. I'll be using a Spike's Tactical pistol buffer tube kit, which gets great reviews. Caliber will be 5.56. Anybody got a suggestion, or hopefully some experience with this? This is supposed to be a fun project using as many spare parts as I can. I'm not planning to send it out. (Never mind whether that's the smartest choice or not.)
Thanks, Dutch
