Our Steel Low Profile Gas Blocks will fit almost any hand guard design. Minimal-profile replacement for factory front sight/gas block won’t interfere with extended-length tactical forearms, while ensuring proper function of gas system for reliable cycling. Protrudes only .5" above barrel, covers less than 1" of barrel length, and adds only 1.4 oz. of weight. Compatible with M4-style carbines and M16A2/A3/A4-style rifles with any length, .625" O.D. barrel. Two steel setscrews keep the block securely anchored to the barrel to prevent shifting even under the force of full-auto recoil. QPQ Finish provides the best corrosion protection and gives a smooth black color that matches Nitride, Melonite and QPQ barrels.

I would buy from this company any . They were spot on and delivered very fast.
Surprisingly good Gas Block for Price!
Out of the box I was very impressed with the nitride finish on it for what it cost. I installed it on my rifle and it has run 100%. Would buy again!
