Which Adjustable Gas Block :confused:

[Hooz]

I have used both the Syrac and SLR DA7 from Rifle works with zero problems. the DA7 only needs one screw to turn and has a detent to lock it in place. Only time will tell if one is preferred over the other but with over a thousand rounds through both I have not had an issue with either so far and both have stayed where I have set them. http://www.slrrifleworks.com/products/ad...-gas-block

Both the syrac and DA7 adj. gas blocks fit under my small MI SS generation 2 hand guards.

I have two of the SLR blocks and three Syrac blocks. My experiences have been exactly as listed above. No issues with either after many rounds.

The SLR block is a bit easier to adjust than the Syrac one handed, but they basically function the same. They also both adjust from the front. A lot of the adjustable blocks out there now adjust from the side, so you need a hole in your forend. Just something else to think about.
