Home Forums Hunting & Shooting AR and Tactical Rifles 6.5 Grendel upper

This is strictly my one and only experience with AR Stoner 6.5 Grendel complete upper. This was an unfired upper I bought from a friend. My experience was terrible from start to finish as far as accuracy. No matter what I shot through it for the first 100-150 rounds was all over a 12" square target @ 100 yards. The more I shot it the better it got but reached a point where it wouldn't get any better for me. After 200+ rounds I couldn't get any better than 4-6" groups @ 100 yards with multiple different ammo manufacturers. I gave up and sold it for about what it was worth. This is the only and last one I will own, but again this was only 1 of 1. Just my 2 cents. Good luck with whatever you choose.
