I purchased an LMT MRP complete rifle last week direct from LMT, took it home, cleaned it thoroughly and lubed it up with ALG Go Juice.
During the first 60 rounds fired, I experienced 3 bolt over base malfunctions (Federal XM193 5.56)
At approx round 240, I encountered another bolt over base. (Federal American Eagle .223)
Current round count - 260rnds.

Magazines were 3 new Lancer 20rounders used randomly. No malfunctions in new Lancer 30rounders.
Rifle is a stock LMT, with the LMT ebcg and 16" mid-length stainless barrel & car buffer. Stock A2 flash hider.

I never experienced a bolt over base in any of my BCM or PWS rifles, so I have little idea what I should do. Re-clean it? Run 200 rounds more to break it in?
