I'm looking for two uppers. One for target and one for HD/plinking. I'm leaning towards the RRA Varmint 20 inch with 1:8 twist for the target. The other I'm looking at is the Sabre Defence Custom 16 inch mid-length with 1:7 twist. This one has a YHM free float installed already. Both are from PK firearms. Just above $600 each. Anyone know of any better deals? I'm building the lowers but don't wanna do the uppers. I really want the HD upper to have a free float quad rail and the target to have a free float tube with swivel stud for a bipod. Is this a little high or a lot high, price wise? And is Sabre Defence good quality?
