Thread: Disadvantages of a gas piston AR?????

They seem like a good idea as far as keeping the bolt and the inside of the upper clean. Wonder what the disadvantages are? I'm sure locating replacement parts might suck.

well you can get an AK at 1/2 the price...

I heard when running suppressed the dont really help. Apperently it still blows gas back into the gun it just comes back the barrel instead of through the gas tube.

I say it adds more weight and parts, and I dont like adding either. Not to mention they are ore expensive.

If I wanted a gas piston 556 I would buy an Sig556. From what I hear they are the nicest AKs ever made.

I have read from many reliable sources that piston uppers may be a benefit to you if:

1. You have an SBR.

2. Fire lots of full auto.

3. You fire most if not all of that full auto suppressed.

4. Fire thousands of rounds a month.

I can't check any of those boxes so I'll pass on a piston.
