SEMI DROP-IN THREADED BARREL FOR S&W M&P Reviews & Ratings
Best Barrel For M&P
I bought this for my M&P 9L Core to attach a suppressor.I ordered the correct file and lay out fluid. I watched the video from Apex. Step by step install was very easy. For my gun the only metal filing was for the lock up on the rear tabs. Watching video and measuring against factory barrel I got the exact fit Randy Lee describes in his instructions. WHAT A DIFFERENCE! This pistol went from 4-6 groups at 20 yds to 2-3. Very consistent round groups with no uncalled flyers. Worth every penny.
