This is a high quality adjustable gas block. 308 is a bit trickier than 5.56 and this gas block does it's job to dial in the wide range of loads. I just ordered another for an identical 223 Wylde build. I didn't have any fit issues with an AP M5 Enhanced but gas blocks may be an item WC could post full measurement specs on. If you're building a 308, get the WC 308 rifle length gas tube. | ||

Wilson Combat M-LOK Rail, AR-15 - 15" | 12/14/2019 |
This gas block doesn't play well with the WC M-LOK AR-15, 15" The bottom of the block rests on the handrail and affects accuracy. I don't recommend to use this block if you plan on have it sits inside the handguard. Go with a short handguard to stay away from this touching problem. | ||
