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.
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!

Bought a .750 and its big brother. After about 40 or so .308 rounds out of each barrel, both seem to do what they are supposed to do without loss of adjustment.
Although I haven't installed, it appears to be solid, functional and good price.
Was on sale, shipped quickly. Haven't tested it yet but seems like it's built well.
I bought some of the older style adjustable blocks from Texas ar and they were okay. They worked but adjustment wasnt easy and you had to lock the screw down. These new ones are awesome. You can adjust them whenever you want and you dont have to lock any settings, it does it by itself.
The gas block fit great, shipped in a timely manner
Order this gas block to fine tune my rifle. Easy to tune and fitment was great. I'm happy with my build and Texas-ar for this gas block.
Ive put 3 of these adjustable gas blocks on. Each one has been easy to fit on the barrel and easy to adjust when setting the gas. They look like they can be broken down to clean or rebuild if need be, but have had one on a rifle long enough to have any issues where i would need to tear it apart. So far Im very happy with these gas blocks.
This is bar none the smallest adjustable gas block i found that will fit under most slim rails. It also has adjustable clicks that appear to be a detent system. Most gas blocks with equivalent specs are outrageously priced. I was able to dial in my Arp Tac6 barrel with 4 shots. No more swipes and great 3:30 to 4 o'clock ejection. Item arrived in 3 days. The gas block also had no tooling marks and is nitride finished steel. This is a no brainer buy, a sleeper. Just buy it you won't be disappointed. I WILL SAVE MY HARD EARNED DOLLAR AND GIVE THIS COMPANY MORE BUSINESS. Thanks Texas Ar for offering quality American made products at a reasonable price.
This is nicely machined and finished and fits the barrel of my 300 Blackout pistol perfectly. The adjustment is a little different than other blocks I have used in the past. The locking set screw is parallel with the gas tube and the adjustment screw is on the side. Both screws are the same size, so you don't need two different wrenches to adjust. The only negative is the screws are metric using a 1.5 mm wrench, which is at least included. I prefer SAE since it's the standard for AR pattern rifles. This a small nitpick, since you really only need to adjust the block once. This block performed well, allowing me to tune the rifle with just enough gas to lock back on subsonic rounds and not have harsh recoil and dented cases with supersonic.
