AR-15 SOLID ADJUSTABLE GAS BLOCK

AR-15 SOLID ADJUSTABLE GAS BLOCK Reviews & Ratings

The Superlative Arms Patented Bleed Off® Mode, direct impingement, gas block for the AR-15/AR-10/LR-308 platform adjusts the gas flow by bleeding the gas out the front of the block instead of restricting the flow like conventional adjustable blocks.

RESULTS:

  • The pressure used in the block is reduced only to the amount required to drive the bolt carrier. The remaining gas and pressure are bled out of the block allowing the system to run much cleaner and cooler.
  • Reduction of wear on the bolt carrier group components and upper receiver.
  • Reduction of felt recoil allowing for faster follow-up shots.
  • Patented adjustment detent is located outside of the block and therefore no contamination.
  • In Bleed Off Mode the gas adjustment screw does not restrict the gas flow; therefore, there is no erosion or seizing of the screw, and no loss of detent due to carbon build up. Although it is removable, we have added a safety mechanism, which stops you from unintentionally backing the screw all the way out.
  • When using SBR’s and/or suppressors the Bleed Off port allows the excessive pressure to be exhausted out of the block reducing blow back.

Works well on Ruger SFAR.
Helped to tame the excess gas on my SFARs when running suppressed. You need to also get the correct length gas tube as the OEM tubes can't be reused with the standard roll pin setup on the Superlative Arm AGB.

Works really good!
So far, i have installed and adjusted this thing block so that my AR cycles properly. Got a suppressor coming in the near future. If money was never an issue, I would have went with the rifle speed block. I am happy with how this functions and the results that i have gotten for half the price of the rifle speed.

Satisfied Customer
I had a handful of bits and bobs needed to complete my kit and Brownell's had everything I needed in stock. Processing took about 1 day and then my order was shipped and received without a hitch. All the items were packaged relatively nicely and accounted for. I look forward to my next order.

Superlative Arms adjustable gas block
I bought this item after finding very good reviews for it. I received the item a day early which was great, only to find that I had mistakenly ordered the wrong one! I called customer service and was helped by an associate by the name of Becky. She was very nice and knowledgeable. She handled my situation with ease. Even more, after our phone conversation she called me back, to say that my card had been declined! During the call it refreshed and was good. That's customer service!
