| can anyone tell me how long a mid length gas system is? i am looking at a rock river arms elite operator 2,http://www.rockriverarms.com/images/products/bb2522.gifand i really like it, the only thing i would do is switch out the hand guard for something like the troy trx extreme battle rail but not sure what length, i am guessing 9 or 10 inch. |
