20” 6.5 Creedmoor complete Upper Review by Jason
I purchased this for X-mas, 6.5 Creedmoor 20”
Always been a DIEHARD AERO PRECISION MAN!this is an addition to a M5E1 enhanced
.308. Aero quality is Second to NO ONE!Aero makes it possible for a middle class man, enjoy serious quality, art,and performance and this 6.5 Creedmoor DID NOT DISAPPOINT,
Speachless. Simply amazing the accuracy of this 20”Upper after breakin of 70 rds down range it’s gettin SUB yes I said SUB MIN,Accuracy. It’s quite obvious that if I’m not splitting holes EVERY SHOT! Is I’m the only WEAK LINK IN THIS PROGRAM! U know ther once was a time I DREAMED of making shots like this. So thank all u at AERO PRECISION FOR your dedication to a Flawless work of art.
And making a man as myself able to afford such work of art. Aero for life!! Once again thank you ALL. JASON M. PHX AZ. (Posted on 1/14/2018)
Great quality, accurate upper Review by AARON
I picked this up for some long-distance shooting, and was not disappointed. I've only had it to 600m, but was getting tight groups at all distances. Have it mated to a CMMG lower, with an adjustable gas block for suppressed shooting and a Vortex Viper HS-LR scope. Very impressed (And not the only AP upper I own). (Posted on 5/29/2017)
AWESOME............... Review by Jimmy
Mounted the 20 inch 6.5 upper on dpms lower. Aero Precision upper fit perfect and snug , no rattle or play at all. Fit was much better than dpms .308 upper. Mounted SWFA 12 power scope on top...got sighted in, 5 shot group could cover with a quarter.......I am happy camper... (Posted on 1/15/2017)
