I will try to attach photos below. This is my second AR build and the purpose is for hunting and long range target shooting. The complete rifle with scope and empty magazine weighs 9 lbs. and it is 40 and 1/4 inches in length. I used these parts:
Anderson lower and upper receivers.
Odin 20-inch barrel with their BCG and non-adjustable gas block (rifle length gas system).
15-inch handguard (BCM-KMR-A15).
Geissele SSA-E trigger(this is the best trigger of any of my guns).
Magpul ACS-L carbine stock and SL grip.
Tubb flat buffer spring and 5.3 ounce heavy buffer.
Surefire 7.63 Procomp compensator.
Burris E1 Fullfield 4.5x14x42 scope (it has hash marks from 100 to 500 yards and corresponding dots for estimating hold for wind drift).
Aero scope mount.
Fake Atlas bipod ($50 Chinese knock-off)
I shot the rifle last weekend and it functioned without fail. It still dents the brass slightly, so I am going to try shortening the ejector spring. I am kind of disappointed with the 1 1/4 to 1 1/2 inch groups (5 shots, Hornady factory loads at 100 yards) when comparing them to the groups posted on the Grendel forum. Based on some of the forum threads, I probably need to refine my shooting technique by dry firing the rifle and watching for movement on the target. I probably am jerking the trigger sometimes and not following through. I was able to hit the 400 yard gong, after figuring out where to hold. This is the farthest distance I have shot at, so I'm still learning about longer range and the AR. I use an old table to shoot off of and sit on a bucket, but it seems steady.
I assembled the barrel to the receiver without using Loctite on the extension and without lapping the receiver face. My question is: should I remove the barrel and square the receiver face and bed the barrel extension with Loctite? If I take off the barrel, I will get it cero-coated FDE to match the stock. When I assembled it, the barrel slid right in the receiver, but it didn't seem loose and I torqued the barrel nut to 45 ft. lbs. as specified by BCM. The barrel seems well centered in the hand guard, if it makes any difference. It now has 80 shots through the barrel. I didn't do any barrel break-in procedure.
Also, when I hold the hand guard and grip, I notice slight movement between the receivers, which bothers me. I am going to try an accu-wedge and maybe make a shim for the pivot pin out of a feeler gauge blade. My other question: is there any other way to remove the play in the receivers? Will this even help? I could try shooting it one more time with the accu-wedge and if it doesn't improve, try bedding the barrel. Any opinions and suggestions will be appreciated.
Thanks, growling dog
