I have a fluted OD green tactical solutions barrel that is brand new and never been installed. I bought this to build a 10/22 for my girlfriend but I was able to get my hands on the pink version that she will prefer. Sorry only looking for cash unless you have a 10/22 x-ring receiver you would trade. Here is some info from manufacturer Tactical Solutions X-Ring barrels are precision machined lightweight replacement .22LR 10/22® barrels.* Machined from 6061-T6 billet aluminum, this .920 diameter barrel is essential for the shooter who demands accuracy.* For a custom fit, the X-Ring barrel has an oversized shank to fit a vast array of 10-22® receivers. The 1 in 16 twist 4140 steel button rifled barrel with 11° crown makes this an accurate and consistent choice for the 10/22® shooter Looking for $190 that is what they go for not including shipping.
