gas block that vents out the front?

[ccoker]

I came across a gas block referenced here a few months ago that vented the excess gas pressure out the front.

I can't recall who made it but I would like to check one out..

on an AR15 all gas blocks vent excess gas out the front............Right behind the bullet.

Possibly

I'm trying out one of the Superlative Arms adjustable blocks right now on a .260. so far so good with about 100 rounds downrange right now.

Superlative Arms indeed..

I have one coming in for review.

They were the manufacture for SLR's gas blocks and I had a long talk with them about their system.

It sure made sense to me.

Whats the advantage?

Whats the advantage?

The Superlative Arms patented “Bleed Off”, direct impingement, gas block for the AR15 platform adjusts the gas flow by bleeding the gas out 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 / pressure are bled out of the block allowing the system to run much cleaner and cooler.

Reduction of felt recoil.

Patent pending adjustment detent is located outside of the block and therefore no contamination.

The gas adjustment screw does not restrict the gas flow; therefore there is no erosion or seizing of the screw / 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.
