I would however say a 20" rifle length barrel (M16A3/A4 copy) or the 16" free float mid length (LMT or LMT clone) will ultimately be better for SR Service class in the long run...

We used R5 rifles in the South Africa Police, they had 13 inch barrels in comparison to the Armies R4 rifle with 18 inch barrel.
Penetration and range was seriously compromised with the 13'' barrel in 5.56 x 45.
