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 .420" 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, .875" 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.
Adjustment screw is located on the front of the gas block for easy adjustments. The adjustment screw clicks and locks in place to make sure your settings do not change. Easy adjustments with 1/4 turn increments for fine tuning!

Fits perfect . Finished very nice product
definitely lower profile than competitors gas blocks. great quality. fast shipping out their door
The fit and finish of this unit is spectacular, for the price it can’t be beat even by other products that cost 4X as much. Will buy again in a heart beat!
I gave it 4 stars because it is well made, I have yet to shoot the rifle I put it on
Excellent machining and finish at a great price. You are getting awesome quality without paying for big name, fan-boy brands. This is my new go-to brand.
Best block I've found including the crazy expensive ones out there. It has all the right features and works flawlessly.
Why is an adjustable .875 gas block so hard to find? This just became a life saver. Thank you Texas AR for having this in stock and super fast shipping
