I was planning on installing a Battle Comp BC51.30 on my M&P10, but I was told that the threads on the M&P10 are to long and would require several crush washers to tighten it up.
I contacted Battle Comp and was told that the BC51.30 would fit on any threaded barrel with a 5/8 x 24 right hand TPI configuration. with a standard length of 5/8 inches.
What Battle Comp wasn't sure about was the length of the threads on the M&P10.
How long is the threaded part of the barrel
Linear Mode
