Gas Piston System Kit for AR standard carbine length
Discontinued - No Longer Available
Finally an affordable Gas Piston retro-fit for your AR15. Our Gas Piston System is easy to install, reliable and performs as well if not better than other, more costly systems on the market. At nearly half the price of other systems our TNW GPS is not only a wise investment but also an investment in time savings.
With the system design you will have less carbon build up on your bolt carrier assembly and internal moving parts. Most of the gases never make it to the chamber area to foul your AR15.
For use with standard carbine 16" barrel lengths.
