Hey guys, I got my XLR chassis for my T/C Venture in .308 a few months ago and haven't been able to shoot it because of shoulder surgery. Anyhow, I finally got everything put together the last couple of weeks and was going to go to the range today and discovered that both my 5 and 10 round AI mags will not lock up with the mag catch. I have e-mailed Kyle but just wondering if anyone else has had this happen.
