Adams Arms .625 Lite Piston Conversion Kit - Carbine Length Review

Weighing approximately ¼ less than our current retro-fit gas block, this new lightweight gas block will make a noticeable difference on your AR upper.
If you are trying to accomplish some weight reduction on your current set up, combining this system with a lighter rail/handguard will definitely be the way to go.
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.
