I have put a Green River octagonal barrel on my Ruger 96/22 Mag. rifle and the accuracy has become better at 3/4" at 50 yards. Green River's .22 mag octagonal barrel was WAY too long for the 96/22 Mag. rifle so I sent it back and got the shorter .22 LR barrel. I had a gunsmith re-chamber it and add a 2nd extractor slot. Also I hated Ruger's lawyer-inspired magazine release "protocol". You had to have the lever partially open to release the magazine. So I filed down the "magazine catch" plug so the lever would stay closed and still permit the release of the magazine. Problem solved! I did this on a plug that Ruger sent me so I still have the original "legal" magazine catch plug for any collector, just like I saved the barrel, natch. Finally, I requested Boyd's Gunstocks to make a laminated stock for this rifle without the barrel band inletting. I just want a plain stock. Maybe they could offer checkering options but it's not necessary for this rifle. I doubt anyone else has modded their 96/22 as much as I have. But if so let's hear about it. Eric B.
