Re: Magpul PMag issues. As weird as this will sound, you need to measure the length of your recoil buffer, and the internal depth of your buffer tube and post it here in addition to the excellent info already provided. What changed? The metal Mag that came with my Stag worked fine however. Correction to original post: If the solution to the feed problem involves a modification to the upper or lower, Ill test the bolt catch and take another measurement as shown in figure 6 (not figure 5). Then collapse that spring ON the plunger, to coil bind, and measure the OAL of both (with spring in coil bind). Note: Firearm will not retain magazines until a replacement magazine catch solution is re-installed. Talyn said: Pmag VS Hexmag. Maybe after Magpul completes their move they'll address some of their mold issues, 'til then it's best to check. You must log in or register to reply here. For more information, please see our My solution is to raise the bottom rear edge of the mag well by approximately 1mm to 1.5mm. This is not the case with PMAGs in many platforms. It may not display this or other websites correctly. To clear, get the bolt to move back by removing the floor plate of the magazine, remove the spring and follower followed by the rounds in the magazine and the 2nd round should drop out. One new winner* is announced every week! Its best to identify these two common issues with your rifle, before attempting to diagnose problems with your magazines. 6: Bolt catch fully extended = 0.359, Fig. JavaScript is disabled. I thought it was a nonissue with the gen 3. So far so good. Display as a link instead, 10: Top of lower receiver to top of magazine catch = 0.696, Fig. I'll try and grab my camera. So, for people who only have AR-15s and only shoot AR-15s, its easy to get tunnel vision and just assume that PMAGs are the greatest, and the end-all, be-all answer for all shooters, while overlooking the needs of other people. The plunger and compressed spring are 0.490. Press the AR MAGLOCK magazine release button. It's a whole lot of details. Similar occurences? Open the receivers to the maximum limit of the pin capabilities. Think it could be magazine springs? It isnt that they are bad (in fact they feed and run very well in certain firearms) but in my years of shooting I have simply found that other products may better suit a myriad of shooters.
