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 .4" 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.

Seems to be well made, tightened down good and snug and rifle operates properly(which is kinda an important feature)!
Opened product. Insected. Fit perfect
Great machining, awesome finish, came quickly. Works perfectly.
Great sale price the block, it has a nice finish but a pretty loose fit for the gas tube. Had to peen the hole a little tighter to keep the gas from escaping .
Fit my fat barrel and works great
