Thanks everyone!
Range Report:
Rifle shot flawlessly from round 1! Tuned the gas system down until it wouldn't strip the next round, turned it up a few clicks from there, and it works perfectly. Put 140 rounds down the pipe. And yes, I cleaned the barrel and lubed the crap out of the bcg before heading out. The accuracy is PHENOMENAL. It'll put bullets on top of each other and in the same hole. I, on the other hand, cannot lol. Thankfully, I'm training with an ex SF sniper, and he's really helping me out with my breathing, trigger placement, and all that. The biggest struggle I'm trying to overcome is anticipation. I'm anticipating the recoil too much and tend to pull my shots. That being said, the only complaint I have is the milspec trigger. Would a two-stage help me out with that? I know I need to spend a lot of time dry firing the weapon, which he said will help a lot.
Overall, I couldn't be happier! I would say first build is definitely a success! Quick question though, I keep missing JP by a few mins when I try calling them on torque specs for their gas block. All I did was tighten it down as much as possible with an allen key and blue loctite on the threads. Will that be enough? Before I go out again, I think I'm gonna check over all the vital bolts and double check torque, make sure everything is good to go. I designed this rifle to be my hunting/fun dmr type, so it did see some rapid fire today (which btw was a ton of fun!)
Also, I was able to take the rifle out farther than 100 yards. Hit a 2-liter coke bottle at 300 with both shots. Hit a gallon milk jug at 400 2/3 times. But the 450ish (maybe 500, didn't range find it) was way up a hill. That one, unfortunately, took about 20 shots to hit. This is where my anticipation was really hurting me. All of those shots were landing about either a foot in front (the terrain was pretty intense) or a foot to the right. Pulled a few to the left. And a flyer over the top. But, on the last round in the mag I nailed it dead center! So I know I can do it, I just really need to work on breathing and anticipation like I said above.
Edit: on the weight, AdamO, I think you are pretty dang close! It weighed about the same as my AR15 without the bcg in or a mag in. Unfortunately, I don't have a scale at home :( I am very curious myself what she weighs loaded down. I'll track a scale down one of these days! I think I'm gonna pick up a couple of 10 rounders for hunting season. Maybe even do the 5 round pmag mod to shave even more weight.
