Great quality, but not sure on the price.


It's Daniel Defense, so you know it has great quality, but to be honest the gas block on my friends AR that only cost $20 looks and feels to be the same, so not sure why I bothered to pay 3x more just for a name.

Great Price!


Primary Arms had the best price for the DD MK12 LPGB. Kudos to the team, again!

Not guaranteed to fit under most rails


Daniel Defense states this gas block is only guaranteed to fit under their RIS II rail system but they do not include this information in the description. Be warned it may not fit under other rails because it has so much chunkier on the bottom than most gas blocks. Had I know this I would not have bought it and would have bought another low pro gas block.
