G&G M4 SD Complete Conversion Set
The G&G CQB-S has a very unique look to it, it features a free floating rail system with a short outer barrel and a long barrel extension that is recessed inside the RIS. You too can have that look on your M4/M16 since G&G is making the CQB-S Front End available separate from the gun.
Includes: barrel extension, outer barrel, RIS.
