I have a 224 Valkyrie that I want to upgrade. I run a supressor on it, and I have the SA adjustable gas block. I’m still getting a LOT of carbon in the receiver and BCG. So, I’d like to install a piston conversion kit. And for fun, I’d like to get a captured spring buffer like the Stealth or...

HK gas piston, the part that takes the pressure from the barrel and turns it into movement. The maintenance book advises to oil it but I am not so sure, it seems to do just the same no matter how it looks. It takes some serious carbon caking on it but it does not seem to have any effect at all on it

I'm building another upper but up until recently had never seen the piston style uppers. Can I build this style with a regular bare upper and lower, or are the parts specific to the piston type? And is there anywhere I can get schematics or detailed info on them?

Anyone know if a Ciener kit or the Spike's Tactical version of this kit can be used in a gas piston .223 upper? I know the .22 is a pretty dirty round to fire. Does using one of these kits get the really nasty fouling coated into the gas tube of a direct inpingement AR? Does the Spike's...

Hi Hide members, I know many of you guys are AR experts. I have researched the superior aspects of a piston AR rifle vs gas AR rifle. I know now Bushmaster makes a piston version of the AR. Does anyone have any experience or knowledge regarding this AR version? Particularly, can I put this...

Hi All, I recently purchased a rifle length gas piston system from Adams Arms for my 20" Krieger/CLE barreled rifle. My rifle previously worked flawlessly with a YHM gas block but I wanted to try the AA system as I have ordered a suppressor. Used a known-good Magpul 20-round magazine. SETUP...

Is a piston driven AR with a can quieter than the regular direct gas driven? I may have a great deal lined up on an Adams Arms piston kit. Thanks

I am looking into purchasing a piston AR. Any advice as to makes and models would be greatly appreciated. I am leaning towards a Patriot Ordinance Factory 223. Please share your experiences.
