Most Helpful Positive Review wtf colt sherman!!!
First off, if you are cutting your buffer you are an idiot and don’t need to mess with firearms. That statement alone told me all I need to know about his ability to install this stock correctly. As an owner of several BCM products, I can say with confidence that this stock is top of the line. It no...

The SOPMOD is the final piece of the MK18 puzzle

by Danny, Verified Owner from NC, United States Written on August 9, 2026
Honestly, trying a few different stocks on a MK18 usually leads right back to the B5 SOPMOD for a reason. Because short-barreled setups can feel pretty front-heavy once you hang a light and a can on them, the extra weight at the back of the B5 actually balances the whole rifle out nicely. The cheek weld is wide and comfortable, which makes getting behind your optic feel completely natural, and it locks down tight on the receiver extension with practically zero annoying rattle. Add in the waterproof storage tubes for batteries and solid steel QD mounts, and it just solidifies that duty-ready feel without looking overdone. This is the look i was after and I would recommend this stock.
