Blue-collar's Review of Osprey Defense AR-15/M4/M16 Gas-Piston Conversion System
I believe the osprey defense gas piston conversion kit is the best in the market. I got rifle length kit for my SAM R built. Everything is we sheen very well, the bolt look amazing. Used mil spec material. If I knew they were going to discontinue the rifleman system,, I would have pick up more then one.
Pros:
- Piston kick will run in any weather condition.
Cons:
- Will only work with mil spec barrel nut. Must find a handcart that will work with the mill spec Donna some modification
Best Used for:
- Personal protection, competitive shooting, Hunting
Would Recommend:
Yes
