Rock River 350 Legend Upper For Sale. This item has a 16.5” barrel with a threaded muzzle and a synthetic stock. The 350 legend also uses the same.346” bore and.355” groove dimensions as 357 mag and 357 max.
All uppers factory built by rra, with rra's superior factory fit and finish. I'm thinking a single 147gr bullet could work for my 9mm handguns, 9mm carbine, and the 350 legend. Similar bullet tolerances also exist for 357 magnum and 357 maximum.
Find gray, black, tan, alpine and other finishes on these.223 rem / 5.56mm,.450 bushmaster or 6.8 spc chambered rifles.
If you want a similar upper but with some changes you will have to purchase a custom upper that will be assembled to your specifications.
