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, .750" 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.

Awesome gas blocks
By far the best low profile gas block on the market. I have been building ARs for 5 years and this is the only gas block I'll use.
An outstanding gas block that doesn't cost as much as a lower or upper. This is a solid product that has a much tighter fit on the gas tube than many name band blocks. I will strive to use Texas AR gas blocks in all my builds.
slid smoothly onto my barrel, no friction, and no play, the rear set screw lined up perfectly with dimpling on my barrel. i ordered 2, and the limiting factor is money to build this awesome product into my next upper
No frills here, just simple perfection. Diameter is great! I literally tapped it onto my barrel with a rubber hammer. Not so tight that it wouldn't go on, but this thing is definitely not leaking! Same with the gas tube hole. Very tight fit, almost make a suction sound when you pull the tube back out. This is by far the best gas block i've put my hands on.
