Hello everyone,

Just wanted to say hello and compliment you on your great website and forums here.

For anyone that is interested there is a new new Retro-Fit Piston Driven System on the market that bolts on to your existing AR-15. Most other manufacturers are making the consumer purchase the whole rifle, but this retro fit system will fit any AR-15 and is made to order depending on your barrel diameter.

Best Regards!
