Looking into getting a Piston kit for my AR. I shoot left handed and suppressed so I get alot of gas blow back into my face. I would like to have the gas stop at the gas block. Does anyone have one they like or used? Also does someone have a take off one they didnt like?

Piston kits are nice , will make ur gun be much cleaner as well especially how dirty suppressors make ur gun . I have run around the same rounds thru my LAR upper /bcg combo as my buddy and mine looks 3 times as used from shooting mine suppressed ...

For starters, try this.

It works very well, is super cheap and eliminates almost all the blowback.

not a bad idea. I do shoot left handed as well.

They used to have these in stock , have not tried one but it's worth a shot

Woops forgot ur lefty

Got a old beat up upper I'll try one on.

From reading, piston is great for F/A work but not much help/benefit in Semi auto.

What sounds great is less crud & gasses coming back into the receiver and your face.

Still looking at these. Seems like there are more than a few to pick from.

I have the Adams Arms piston on a 7.5" and it runs great with any ammo I have tried. On the short barrels its a benefit even in semi

Nice I plan on running it on a 10.5" or a 12"
