Viltor Gas Block


I think these are great, every where I looked they were out, Primary Arms came to the rescue with great product availability

Was exactly what I needed


My newest AR build started out as an M4 with a railed low profile gas block. It was too high for the hand guard I was using so I bought this VLTOR. My barrel wasn't dimpled for a set screw type gas block and there were few options in a non adjustable clamp on style. This gas block was exactly what I needed. It also fit using the Diamondhead VRS T hand guard which is one of the smallest ones I've seen, so you should be good with just about all other hand guards. I haven't shot this rifle yet so I can't tell you about that aspect but I have no doubts it will function properly. As always, Primary Arms' website ease of use and shipping times were spot on.

Excellent lo-pro gas block


One of the best engineered lo-pro gas blocks on the market IMO. I prefer the twin screw clamp attachment to set screws used by many other companies. VLTOR has a "sighting hole" in the gas block too. Turn it upside down on the barrel, use a Sharpie to mark the gas port location, spin the block over 180 degrees and install with thread locker for a perfect fit.

Quality gas block. Fit my barrel perfectly.

I heart Vltor


It's a gas block. Idk what else to say, beyond it makes me happy knowing it's made by Vltor.

Thank you.
