welp i thought i would post this..jus FYI..i replaced my 18" butler creek carbon barrel with an 18" heavy match Adams and Bennet flutted barrel..well i must say right out of the box, it was extreme tight fit to my reciever. Once at the range the gun shot very well. At 50yards i was gettin consistant nickle size groups (couple were out, but that was me) it was so consistant i thought i was missing cause i could only see 1 hole on the target, found out it was jus that accurate, the barrel never got warm, even with rapid fire..other than being heavy (what ya expect with heavy match). it was very good barrel. the only odd thing that was goin on was , i tried shootin sum Clear Butler creek 30 round mags. it didnt like those too much..i was gettin serious "Stove piping" . dunno why..but the factory 10 rounders went flawless, even during rapid fire..i shoot all kinds of rounds out of this barrel, Standard VEl, HI-VEl, SS, the SS werent that OFF at 50 yards by bout 1/2" , i was surprised, i had major drop when i had carbon barrel..next time ill post pics of my groups,,i was very happy with the barrel,, ALso when i came home to clean 10/22, i ran a patch with bore solvent and a couple patches with CLP and a couple that were dry and it came clean pretty easily. welp that is my story and im sticking to it..lol. peace. *edit* to add, also , the price of the barrel was super cheap as far as i was concerned, i got it for like 110bux..
