Neither upper or lower is an AR.
from the look of the lower it doesn't look compatible with an AR upper so I think it is very likely to be NR wich would be great
This does not look like a chassis at all.
Looks like a M1/M14 option rod and M1 barrel/gas system.
Looks like an AR lower
I want one too. But I doubt it is a chassis. Look at it. It's got a whole different receiver.
Well, I'll be. There you have it, new gun.FYI, to finally put this chassis non-sense to rest...
Me: Is the Osprey Armament Mk-36 a new firearm or a chassis system for the m1a?
Osprey Armament: New firearm. Not a chassis. Thanks!
Well, I'll be. There you have it, new gun.
Not an AR variant.
Huh? It is an M1A/M14 receiver. This is no different than using an M-14.ca chassis. The only difference is it uses an AR-15 trigger and a different mag well.
