    If you own a SCAR 16s and run Magpul PMAGs, please watch this video.

    Have you emailed Magpul regarding this issue?

    No. But the guy that originally found the issue has contacted both Magpul and FN about it I believe.

    There are so many PMAGs in circulation that I wanted to let people know that the problem exists and that if they're running PMAGs in their SCARs, they need to make this modification.

    For those of us who can\'t view the video, what is your issue?


    Having problems getting them to drop free/hard to get in? or is this some other issue?


    If its the mags are hard to seat/don\'t drop free, try E-mags, they\'re designed for guns with the slightly smaller mag wells found in many STANAG weapons.

    The issue is that with PMAG's the magazines cause the bolt hold-open device to stick up partially which in turn causes the bolt to whack it (but not lock back) going forward with each round fired. It causes damage to the bolt hold open device and it has caused damage to at least one users bolt.

    Here's what the bolt hold looks like with a standard NATO M16 mag inserted.

    Here's what the PMAG looks like in relation to the bolt hold. You can also see a slight impact mark on the back of my bolt hold where my bolt/carrier has been hitting it. I did fire the rifle with unmodified magazines a few times, but not many. Maybe 100 rounds.

    The solution is to use a Dremel (or file) to remove material from the back of the PMAG that's causing the bolt hold to stick up. Here's a shot of a modified mag and a non-modified mag.

    Which is great, except for those of us that have a stock of PMAG's already. I'm not going to run out and buy a bunch of EMAGs to go with my PMAGs and try to keep them separate.

    That's why God gave us the Dremel.

    true, that's very legitimate use of the Dremel, as opposed to Glock frame mods

    edit: I wasn't trying to be critical, I was just pointing out that it shouldn't be a surprise that the pmags would have trouble with a rifle that is in the euro style, which the emags are made for

    Oh yeah... :supergrin: You won't catch me going anywhere near my Glocks with a Dremel. I like them too much.

    +1, the Scar is supposed to work with AR mags (Pmags). It would not even be worth owning if it was not AR mag compatable.

    More like STANAG exists for a reason.

    thanks for the heads up. if you have access to an emag will you check to see if they do the same thing?

    Good thread but before I took the Dremel to my $18 windowed Pmag I would just run the $8 metal mag and not have to worry about this. Not that I will probably ever own a SCAR. But at least I know now.
