Reviews & Ratings for Spikes Tactical Adjustable Low Pro Rifle Gas Block — 17 reviews — Page 1

I had my gunsmith build my new rifle. After he finished it for me i went to the range. My weapon would not cycle no matter how I adjusted this thing. I took it back to my gunsmith and he confirmed that it was junk. Read on AR-15.com and you will be hard pressed to find anyone that didn’t have the same issues as I did.

Literally just installed it and from what I can tell by dry firing it....it's smooth. Clean break, no wiggle in the housing, no play in trigger pull and a nice audible "click" on resets. I'm buying another one right now.

Adjustable gas blocks are a must when running suppressed. Spikes can be hit or miss but this one is a hit. Would definitely buy again for a future build. Everything it says it does, it does. I feel like they could do better on the price though.

Spikes low profile ajustable gas block . Has a clean black finish with a great laser etched spider . Has many adjustment positions to tailor fit your ar15 .iwould buy this gas block again. i would also recommend this to all!!

What can I say, it works quite well, allowing me to alter the gas flow for various loads and suppressed use. Easy to adjust, and quite diminutive; it fit easily under the magpul forend stock. Easy to get to as well, and the supplied hex wrench is long enough so as to not conflict with the barrel during adjustments. Instructions were easy to follow.

So the weird piece sticking out the front is a ball bearing and spring that ratchets the set screw and holds it in place. very nice design. .............................................................

Been using these on a few builds and have always had good luck with them. Nice snug fit over the barrel. Positive click for each adjustment is a nice feature and makes it easier to keep track of your adjustments. Highly recommend.

i baught it because I couldn’t find a superlative arms gas block. The destiny isn’t as active as my superlative arms gas block. And it seams kinda cheap. It could be because this is a .625 and my superlative gas block is a .75

To give credit, this is designed by superlative arms with spikes logo stamped on it. That said, it's the best adjustable gas block out there. It vents any excess pressure beyond what you set it at. I run this on a 7" barrel ar15 with and without a suppressor with no adjustment of the gas block. I run this on a 18" ar10 with and without a can with no needed adjustments. Set it and forget it.

It was easy to install the Spikes Tactical Adjustable Gas Block. It is the exact same product as Superlative, except the Spikes Tactical Logo. The installation was easy. My barrel came with one dimple and I added the second one by tightening the first set screw down on the dimple and transferring the second drill point using the second tapped hole in gas block. Follow the directions and you will have your rifle’s gas system optimized after a few rounds. The adjustment screw has clicks you can feel. After winding the screw out 4-1/2 CCW turns I started turning the screw CW until the rifle failed and to eject. Then one click CCW and it cycled. Fully gassed, it was ejecting almost 1 o’clock. After adjustment, it ejected about 3 o’clock. I was able to reach through hole in my hand guard and make adjustments without taking the hand guard off. The key is to use the a hex key a ball type end. Very satisfied with this product in regards to the fit, finish and function.
