So 6,000 rounds total through the upper and piston?

No, the upper has 2k and the piston which came off another gun has 4K. I installed that piston on the original weapon.
Real nice piston system.

Thanks for clarifying that for me Todd.

It functions fine, I just want to build a 9mm upper to put on my SBR to use w/ my suppressor. Also, Osprey Defense has excellent customer service!

I will negotiate a little bit, but it's priced spot on.

So if put on my pistol lower then no buffer of any kind is needed? Can it be completely flat in the back?

 

[Doc Holliday]

No, you'd have to have a buffer tube, it just doesn't have provisions for putting a stock blade on it. The pistol buffer tubes are typically foam covered. Maybe someone can chime in and tell us who makes them.

 

[nola_]

I have ar pistols and understand pistol buffer tubes, but if this has a piston system then why is a buffer tube needed? Or is this not the gas piston system I am thinking of?

 

[Doc Holliday]

Even with a piston system, it still has a full-length BCG. The piston system replaces the gas tube and pushes the BCG rearward; it is still buffered & uses the buffer spring to return it to battery.

Ok I'm confused.... If I were to have a piston AR rifle couldn't I have a folding stock on it? How is this system different for an ar pistol? ( no I'm not looking to put folding stock on pistol, just trying to figure out how it will work for a rifle but not a pistol) thanks,

 

[Doc Holliday]

I don't know of any 5.56/.223 AR that will accomodate a folding stock. I'm confused, too!

In this case the piston replaces the gas tube only. The recoil spring is still located in the but stock.

I believe the side charger ones are the ones with folding stocks

BTT.

Reasonable offers will be considered & I will part out the upper and the piston system (it is carbine-length).
