    Pistons, springs, buffers

    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...

    gas piston.jpg

    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

    Gas Piston AR's (POF-USA vs LMT vs LWRC)

    I've read up a lot on how the LMT's and LWRC's stack up against each other but does anyone have any experience with Patriot Ordnance Factory (http://www.pof-usa.com/)? If so how do these compare? Thanks in advance, Drew

    differerence between gas and piston AR uppers

    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?

    Ciener .22lr Kit work in a Gas Piston Upper?

    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...

    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
