    There are three different types of buffer tubes. The standard, Mil-spec or Commercial

    .....And the proprietary or what ever some call them which are not manufactured to any spec. These appear to be the third rate OEM Chinese made units that are flooding the market.

    If you stick to the real or quality brand mil-spec you will never have any issues.

    I tested those exact mags with multiple mag catches and had no issues in the Sporter. Oddly enough my stag 10 has that issue with the 308 version.
    Try a different mag catch of you can

    Stay away from buffer tubes with the little pin notch and the problem won't happen.

    I did run I to an issue with my BCM tube only making it a couple of threads into the receiver. I had a spare Vltor tube that was fine.

    Buffer tube threads can get dingned up at the factory from bumping into other tubes and what not, and prevent smooth insertion. Are the threads nice and sharp/clean all around?

    I had two tubes I tried. 1 went in with basically size on size fit. It was really tight. I ended up having the chase the thread on the CCS tube I settled on using.
    The thread seems needlessly tight.

    Both BCM tubes I have fit no problem. Check your threads, I’ve had new tubes show up dinged like Dietz said. A couple minutes with a file and they were good to go.

    The actual threads were oversized vs the dd and vltor tube I measured. Plus the bcm tube wasnt machines right in the inside. There was a step about 3/4" from the end that was about an 1/4" smaller inside. Could not use a jp scs in that tube. It's in the parts bin labeled NFG
