View Full Version : Thoughts on AR-15 Gas Piston Conversion

Hi Guys,

Looking at building my second AR and I am thinking about doing a GAS Piston setup. I have searched through the forums and did not find the info I was looking for. So far I have seen Conversion kits from Adams Arms, CMMG and Osprey Defense. I have not searched for complete gas piston uppers yet.

This build I will be going with a mid-length 16" barrel and was thinking about doing a 6.8 SPC.

What are your thoughts on the gas pistons systems? I read they are suppose to run cleaner, cooler and more durable? Correct me if I am wrong? Any drawbacks to having this setup?

Would you recommend changing my current carbine build as well?

I will be doing some more research on this so any info is greatly appreciated.

Discussed to death already!

Yes, piston has it's advantages, but will these be things you actually need or will use?

A quality dedicated piston upper will be superior to a retro kit.

Ultimately IMO if you want a piston driven rifle, get one that was designed for it. Would you want a DI Ak?

I just realized this will be like beating a dead horse as I read a post on AR-15.com

Seems it's more beneficial to a full auto or suppressed system.

Agreed about the "Would you want a DI Ak?" statement.

Thanks for the info.
