I have two uppers that I am trying to choose between for an SPRish build. I am going to use a PRI handguard that I recently got from ADCO, a Larue SPR scope mount and a Nikon scope. Both uppers are shooting 5 shot groups of an inch or slightly less at 100 yards with two generic handloads, one 55 grain and 1 69 grain. Upper #1 20 inch Colt 1/7 chrome lined government profile barrel. This upper is not currently free floated. It seems to shoot either of the above loads about the same. I bought this barrel used, but it gauges as almost new. Upper #2 16 inch Sabre chrome lined government profile MID-Length barrel that is currently free floated. This upper has maybe 200 rounds through it. I shot both of them yesterday hoping one would outperform the other enough to help me choose, but as stated, they shot about the same. I plan to shoot the assembled rifle out to 500 yards. Thank you for your input. |
