Adams Arms Railed .750 Gas Block Piston Conversion Kit - Choose Size: Pistol, Carbine, Midlength, or Rifle 

Adams Arms has discontinued including those two parts in their current kit edition. Since the receiver bushing is only an additional guide and has no load bearing properties, it was deemed unnecessary and removed from current kit specs. If your kit doesn't include those parts, then you have the latest kit by Adams. This kit is lifetime warranteed as such and does not require that bushing for proper function.

Adams Arms mission is to meet the engineering and design needs that will improve any flaws in the current AR15/M-16 rifle platform.

There are those that believe the current AR15/M-16 Platform should be replaced with newer rifles costing much more than the current system in place. What these companies and/or designers fail to recognize is that there are millions of the these rifles already in service around the world, whether owned by Private Citizens, Military, or Law Enforcement.

The Retro-Fit Piston Driven System developed by Adams Arms will transform and revolutionize the AR15/M-16 Rifle into a modern day platform that will continue to be relevant for many more decades to come.

Additionally the Retro-Fit System offered by Adams Arms will save Law Enforcement, Private Citizens, and other entities thousands of dollars by offering a simple upgrade option, instead of costly replacements.
