Best low profile gas block for M&P 10?

Dutch_Spartan · Nov 5, 2013

Hello all, I want to replace the standard handguards with a 13.8" Troy MRF LP quadrail, but am confused as to what the best brand for a low profile gas block is. I read some of you weren't too happy with the Troy, others suggested Sadlak or VLTOR. Also what size should I order? The Troy comes in 0.936 and 0.75 inch. Any help would be greatly appreciated.

The only cautions I am aware of are the clamp on styles, other than that there just isn't much to them.

Adjustables are another matter and I have no first hand info

I have narrowed it down to these 2:

Troy Industries .750 Low Profile Gas Block (2-Inch )

and this one

which one is better? will the 2 inch one fit?

I won't speculate which one is better, but I put the .75 inch low profile on my latest build, which placed this block over a Yankee Hill Machine 20 inch barrel. It fit perfectly. So far, so good.

Either one of those should work fine. The set-screw type blocks should have plenty of room under the MRF handguard.

I prefer the clamp style gas block. They can be spread slightly for easy installation and I believe they are more secure than a set screw type, Especially when there are no dimples on the bottom of the barrel. They can be a tighter fit under a handguard. I used a Vltor under my MRF handguard. There was plenty of clearance.

I personally installed

No problems at all slightly tough to start the roll pin but that was the roll pin itself not the block.

Thanks for the advice all, the small Troy is ordered.

+1. YHM makes a nice clamp on gas block that I have used several times on AR-15 builds, some with Troy TRX hand guards.
