Piston Kits

[Crews]

I do a lot of high volume hunting with suppressed SBR's... 6.5 Grendel, 6.8, etc. Seems like there's always too much gas with these rounds, even with an AGB up front. I don't mind cleaning every now and then, but seems like the filthiness is almost always an issue. Especially with things like dirty brass sticking in chambers and stuff like that. Would a piston kit be worth my time and effort? Not so much gas in the receiver seems nice.

Grab yourself a superlative arms piston kit and call it good. Solid piece of equipment and the piston spring is a mag release spring. So you can buy a twenty pack of springs and be set for a life time

checked it out, looks nice. Do you have one? If so, how do you like it? Any pitfalls or suggestions on how to set up?

I've had a couple and there pretty bullet proof more or less, for the money it's worth the purchase. Minimal maintenance and the cs is top notch it's a pretty plug and play type of system. Hope that helps out.

Piston guns run just as dirty in my experience

Piston guns keep dirty gas OUT of the receiver. I can shoot thousands of rounds and my BCG will be cleaner than a gas gun shooting 10 rounds

Shooting thousands of rounds suppressed, an lwrc repr and superlative arms kit run just as dirty if they're overgassed. It's coming down the barrel.

Just be mindful and do your research, some of these kits put too much stress at an angle on the BCG forcing it to wallow out the upper and cause all sorts of problems. Years ago some company's product fucked up a lot of rifles. Forget who it was or if they're still around.

A complete upper from a quality mfg. might be wiser, I don't know.

I want a piston 5.56 but am probably gonna wait until FN rolls out some more 16's.

If I didn't have so many AR's to begin with I'd consider an HK, those are supposed to be the end all, be all of piston AR's.

I am running superlative piston on 2 of mine,They have been awesome with over 700 rnds on both rifles with no problems.It is imperative that you get it installed with NO BINDING of the piston rod as it passes thru barrel nut ,install with some handguards can be problamatic you need clearance with no binding,rubbing and you will be good to go very clean bolt assembly as well.
