LT Mac of the HMSG has written a review of the Viper Xm-177:
Hey Troops, LT MAC here. As you know I just got my Viper Xm-177 review up on our Historical Military Simulations blog.
Check out these new reliability videos!
I stand by my review:
“The Viper XM-177 is the best air soft gun I have ever held. The workmanship is better than the Inokatsu guns in my opinion. As soon as I get my hands on the M16A1 version I will have my 2 primary combat weapons. In combination with the ProWin 20rd magazine they are a very realistic and satisfying combination for Vietnam operations.”
