SIG MPX Goliath +20 PCC Basepad by Taylor Freelance
TF went back to the drawing board and redesigned their SIG +20 using the successful "Goliath" concept (see our Goliath +20 and +30 for Glock-mag-fed carbines). To get there, we had to re-think everything, and added a custom follower!
I have to say works as advertised no problems!!!
