Does not fit a ruger 10/22 carbine receiver - TRYBE Defense Ruger 10/22 .22 LR Threaded Rifle Barrel

I tried 2 of these. The finish is fine, but the 'butt' of the barrel that inserts into the receiver is too large in diameter. The OEM is 17.45mm and this item is 17.60mm. I tried to reach the company but their website says 'contact the seller' - couldn't find any support email or phone number. I did buy the other model of this that says 'heavy', this one is pencil, and the heavy fit my Ruger 10/22 Target well. I was shooting MOA groups at 100 yrds with it. I cannot recommend this barrel due to poor QA I assume.
