I'm a new poster here and I don't even own an AR yet, but tried one at the range the other day and might be getting the bug.
A guy at our club had one of those cheap Bushmaster Carbon 15's he was playing around with. I asked him how it shot and he said he's put about 500 rounds through it without so much as a hiccup. I tried it out, but was having trouble with the red dot that came with it, as I have astigmatism and it looked like a glob of grapes to me, even with glasses. The trigger also felt like a washboard and broke at 7.5 lbs. I told him I'd like to see what we could do with it to make it a shooter, so we took it back to my house to work on it. I very lightly honed the tool marks off the hammer contacts, not removing more than a thousanth, so I wouldn't ruin the case hardening, didn't change the contact geometry and got the trigger to break at 6 lbs. very cleanly.
I asked him if I could put a scope on it, just to see what it would do. I had a cheap, Leapers UTC 3X9 on my Ruger 10/22 and installed it on the Bushmaster, got out the sandbags, went back to the range and sighted it in, using his American Eagle 55gr ammo.
We then spent the next hour shooting one inch groups at 100 yards with it. I really never expected a low end gun to shoot this well and was very surprised it would. We found some JP Enterprises 4.5 lb springs at Midway and when they get here, we'll see if we can do even better. I'm now planning on building an AR and if I can get this Carbon and Leapers scope to shoot this well, I'm wondering what I can do with a good AR and a good scope.
