I have a used 20" green Mountain blued bull barrel. which is a tack driver. 1.00 groups at 75 years with cheap ammo.
I have had it for a few months and have 100 rounds threw it. going to a diffrent twist to run subsonic ammo.
20 overall length. 19" from receiver, will require a bull barrel stock or standing to original stock.
picture it to show barrel mounted on gun, gun or optics are not included just the barrel is for sale.
