My Day At The Range WIth My First AR....An M4 A1 Bushmaster Carbine
I know, I know, it's a Bushmaster, generally considered one of the lowest end, poorly built AR's out there. Well according to what I have read at several other forums I frequent, they can be made to be dependable and a decent gun, that shoots fairly accurately. First, I torqued and restaked the gas key cap screws, though I did not replace them with larger ones per the suggestion of one post I read. I also retorqued and staked the castle nut as suggested. Two major problems according to what I read here. My next change is to the extractor spring setup. I reassembled the gun and headed to the range with a 200 round value pack of American Eagle Tactical 55gr. 5.56 x 45 FMJ's.
I walked out to the 50yard backstop and stuck an 8" Shoot-N-C target on the panel and went back to the shooting line. I loaded 10 rounds and split the orange bullseye dot with the top of the front sight, and centered it as best I could in the center of the rear A1 style peep. I then shot all 10 rounds from a standing position, using the strap wrapped around my left elbow to stabilize the gun. I am new to AR's I don't know what is considered to be a good shooting rifle, but I am very pleased with the results. I read somewhere that the Bushmaster is a decent entry level rifle and I believe I agree with that opinion. With the 200 rounds I put through the rifle today, I now have 350 total and no malfunctions or misfires. Here is the result of that 10 shot effort.
