I have a complete brand new never shot bear creek arsenal 450 bushmaster side charging upper for sale. The upper has an 18 inch stainless steel barrel with 1:24 twist. The upper will come with one D&H 4 round mag. I ended up with two of the exact same uppers so I'm selling this one as I only need one. The other upper is very accurate and functions as it should. Can meet within a reasonable distance. $270 reduced to $250 View attachment 290723View attachment 290724
