OK so I think I'm confused as a pickle about how I should set up a well firing AR for both carbine an short pistol lengths. I just made a 16" AR (which my big big post about isn't showing up for some reason) I think mods have something to do with that. But anyways so I made this AR and used a sprinco blue spring and I have an adjustable gas block so I was trying for so long at the range to make my bolt lock back and sometimes it would and sometimes it wouldn't even if the gas port was wide open while using the ranges fragment ammo that noone else has a problem with so for a while I was trying to figure it out and then I thought maybe it's the spring, so I ordered a springco white spring so now I got that spring and I'm excited to try it at the range to see if it works better.
I'm reading and seeing youtube videos all about getting the right buffer to fix the problem I've been having. I have an LBE carbine standard buffer but I'm thinking rather than using a heavy buffer wouldn't it be best to adjust the flow of gas coming from the gas block using an adjustable gas block? I would think that would be the best option that will make less wear on the bolts and stuff but why don't I hear about that much? usually people are talking about getting the right buffer. Is it that people just don't usually turn to an adjustable gas block? I don't know why that wouldn't be more popular especially if it will make it so it just sends the right amount of gas and (I think) reduce recoil and reduce excessive wear due to to much gas blowing back the bolt harder than it needs to. So I'm wondering when I build a pistol with a 7.5" barrel, can I just use a standard carbine buffer and maybe a spingco blue spring since it's stiffer than the white and use an adjustable gas block so gasses arn't so violently pushed into the bolt and stuff?
