Amazing
Finally went to the range , the temp was 102 degrees with a 12 mph gusts , full value ,barrel is made by DEL-TON , possibly SHAW. Using 9 year old reloads with pulled 55 gr FMJ's and IMR 3031 powder , right out of the chute , a 4 round 1 inch group at 100 yards , grouped at 10 o'clock. Had not adjusted front sight , only rear sight with a laser. Using a mid 60's upper by colt/alcoa , and here where it stops , I forgot to file the M4 feed ramp guides into the upper , totally my fault , as for the barrel , fit and finish were spot on perfect , front sight was installed perfectly when it arrived. As for my screwup , it was the most I needed 3 hands 2 round chamber/ feed jam I have ever seen. Don't be afraid or hesitate to buy , its worth a look. Contour was USGI A1 , as chrome lining , I dont see it. Used a A2 flashier , new crush washer. All in all , a 100 % product. This puts my faith in the AR platform back to 100% , even after the H-BAR by COLT disaster back in the 80's. Well done AR15 discounts , well done !
