Most Helpful Positive Review Guntec gas block
Fit well, functioned as it should. Didnt need any extra adjustments and lined up easily with the gas port. Several hundred rounds later, it is functioning as new. Easy to install, gas tube fit tightly but not to tight.

Perfect fit

by MDB76, from TX, United States Written on April 1, 2022
I used this with a Franklin armory 7.5” pistol barrel and TRYBE hand guard 7” to finish a collapsible pistol with a folding brace. So far works great with the set up on a PAlmetto State Armory lower. I was please to find the description and simple installation to be exactly what I was looking for.

Suprised and satisfied

by Donald, from TX, United States Written on December 15, 2020
Considering the price, I am very satisfied. It was a smooth tight fit, lined up well, gas tube and pin fit the block well. Very clean lines. Light weight. For the average shooter, it is a great product. If running matches, you may want to go with the steel block. Overall, worth the purchase. Thanks.
Pros:
  • GREAT PRICE
  • Great Fit
  • clean look
Cons:
  • None
Best Used for:
  • Practical shooter

Great product and great price

by dsears17, from NE, United States Written on July 3, 2018
Received in timely manner. Install was easy and it works great. I used it on my 300 Blackout build with no issues. I have put several rounds of ammo through this gun and it has run flawlessly. I would recommend it to anyone.

Absolute garbage.

by Tex, from TX, United States Written on June 28, 2018
If you want a gas block that’s made of solder then this is for you. Set screws don’t hold a thing and my barrel had indents to help it out! When punching the roll pin into the gas block, the gas block had the same properties as dry solder and basically crumbled and flaked the inside. Leaving metal pieces clogging the hole for the roll pin. I’ve built many ARs and this is the worst gas block I’ve ever used.

Guntec Gas block and tube

by Turnkey, Verified Owner from AL, United States Written on June 21, 2018
Gas block seems well made, it has set screws set at .400 on center with black anodized finish. This was used on a 308 barrel with a .750 barrel. This product does come with a roll pin. The gas tube that comes with the package seem nice and was easy to align and insert into the block.
Pros:
  • Price
  • Fit
  • Roll pin
Cons:
  • None
Would recommend: Yes

gas block and gas tube

by brad, Verified Owner from WA, United States Written on December 13, 2017
The gas block came with the set screws needed and the pistol length tube came with the roll pin that was needed to install. HINT. Get an extra roll pin or two....they will disappear.
Needed no fitting to put together.
Pros:
  • Good fit
Cons:
  • None
Best Used for:
  • home builders
