What is the SUPERLATIVE ARMS LLC - AR-15 Adj Piston System W/Solid .750" Gas Block Midlength RH?

SUPERLATIVE ARMS LLC RIGHT HAND ADJUSTABLE PISTON SYSTEM W/0.750" GAS BLOCK FOR AR-15

The Superlative Arms patent pending “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.

NOT RATED FOR 300 BLACKOUT IN PISTOL LENGTH

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.
Patented 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.

Guaranteed Flawless Performance

Well designed and manufactured. This piston system works reliably.

Works good. Must plan for good result

The Superlative Arms piston kit is a great way to produce a reliable, accurate, and clean rifle. I built my latest AR1 5 around the piston kit, which is to say, I read the specifications on the gas block and bought a handguard that fit, a Samson Manufacturing Evolution Series, Every else was a standard build. I did have a problem with gun cycling at first. The problem was poorly made buffer tube. I replace the tube and it cycles like a charm. My only complaint is the piston spring. It disintegrated after a few hundred rounds. I called tech support and learned that the spring is optional. I eliminated the spring and the gun runs reliably. I shot a deer with it. The deer collapsed after being hit with Federal Modern Sporting Rifle(MSR) 62 grain bullet at 120 yards. I shoot the rifle in competitions. I shot 100 rounds with a clock time under 180 seconds. It is reliable. I recommend the kit to you for a reliable, accurate, and clean firearm.

Nice build quality, but..

Nice slick looking product, price is decent for what you get! But if you plan on putting a free float forend on it be sure it will fit properly.. I bought this to use with a FF forend from Hogue but it is too large even though I have seen this exact kit marketed as "low profile". I am sure it's a great kit but I will have to return it.

Good suppressor set up

The system is smooth it does work but unless you're running suppressed all the time it won't cycle all ammunition it won't cycle tula it won't cycle any of your imported steel case stuff reliably. Slap a can on it and yeah it'll run flawlessly. But it's now been relegated to a back corner of the gun safe because I like something that will shoot everything.if you're looking for a piston system that really works and works with everything PWS all the way.

Disappointed

This system is capable of functioning well for roughly 500 rounds. It isn't a self cleaning system and once it gets clogged with carbon disassembly for cleaning is virtually impossible. The 9/64 allen wrench needed for field stripping is not suited for the task. An external T-50 torx feature should work much better. A self cleaning system would be the best design.
