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, .936" 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.

Block was just as described. Perfect fit with no mods required.
I've built a lot of AR's and have purchased a lot of parts from a lot of different companies. Usually choose the more expensive parts assuming they are better in quality and finish but I was told by a buddy that these Tactic guys know how to make parts and don't charge the markups that all the other name brands do. So I gave them a try, hell for the cost of these parts how can you not give it a shot? After I received it though, anytime I need parts, I'm checking here first to see if they have what I need.
