Need Help Trouble Shooting Some Problems
I have a BCM 14.5" Midlength rifle. I took it out to the range on Saturday for the first time, and I experienced a few issues that I need some assistance with.
First, I lubed the BCG well before shooting, but I did not break it down and clean it before hand. I found that after inserting a 30 round PMAG into the weapon and firing about 3 to 4 rounds the rifle would begin to fail to extract and cause a double feed. I am running an H2 buffer and Full auto BCM BCG. The ammo was Remington 55 grain .223. The problem seemed to stop once the magazine capacity was decreased by about 10 rounds or so.
My first guesses about the issue are that it is either a magazine problem, or that the ammo was too low powered to handle the heavy buffer/BCG and didn't generate enough recoil to extract the fired casing. Any thoughts?
My second problem involved my EO Tech XPS. I installed it per the instructions supplied. However, after about 5 or 6 rounds the device would loosen up and fall off. I did not loctite the tension screw on the sight. So I am guessing this is the problem.
