The Guntec rail is very high quality and comparable to many other higher end rails that cost 2x or 3x as much. Handguard is lightweight, made from high quality 6061 aluminum and mounting system is rock solid.

Gas Block diameter is 0.750 and is made out of steel (not aluminum).

*Optional* - Upgrade to an Adjustable Gas Block. Great option if you are using a suppressor or just want to fine tune your system.

*Optional* - Upgrade to a Black or Stainless Competition Muzzle Brake. This is an enhanced version of the popular style muzzle brakes. The baffles and ports are milled larger to drive pressure up and to keep the muzzle down more effectively.
