Q:
will this fit on Heckler Koch MR556 ?
Asked by:
David B Broadus
- 8/11/2022
A:
It will work with any lower that accepts a mil-spec AR-15 upper and to the best of our knowledge the HK lower is compatible.

Q:
Recently bought a complete Aero Precision 300 Blackout upper 8” barrel with M4E1 threaded receiver, a Low Profile Pistol Length .750 gas block system and Atlas R-One 7” M-LOK guard rail 1.3” inner diameter, 1.5” outer diameter. Do you by any chance sell the piston conversion Kit that would fit my current firearm? Or do I have to purchase a complete upper form you in order to get a 300 Blackout complete upper??? Your 13.5” barrel is in Stock.
Asked by:
Craig Brubaker
- 2/2/2021
A:
We do not offer a piston conversion for the 300 Blackout rifles. Due to this caliber needing a pistol length gas system we had to design a rocker bushing for the upper receivers which makes the piston system non-compatible with mil-spec upper receivers. This rocker bushing allows for pistol caliber piston system op rod to rock back into the upper receiver which allows the end-user to disassemble the piston system for routine maintenance. Without this rocker bushing, end-user would have to remove the gas block for piston system maintenance as seen in other piston systems.
