konkapot Posted January 10, 2021 Share Posted January 10, 2021 Anybody know firsthand if the MBX Caspian mags will work in older style/Gen 1 Caspian guns? Link to comment Share on other sites More sharing options...
tomjerry1 Posted January 11, 2021 Share Posted January 11, 2021 That's a good question, had an early Caspian frame for a short period, frame cracked above the mag release. Caspian replaced it with the newer square trigger frame. I have been using MBX since I can remember, but don't remember if I was with the older frame. Give MBX a call. Honestly don't know why they wouldn't. On their break from making Caspian Mags, I started using Meggar/EAA large frame mags w/Taylor Freelance magwells. Takes a little work, but they function great. MBX are great mags, you can sell your Dawson Precision tuning kit, I have never used it on MBX, right out of the package. I also, can not speak to the new mags MBX are producing for the Caspian, I had alreagy switched mags before MBX had them in production. Link to comment Share on other sites More sharing options...
caspian guy Posted January 11, 2021 Share Posted January 11, 2021 (edited) I had/have one of the first batch of the 170mm mbx mags for the Caspian frame. It seemed like a nice product and fit my second gen frame fine. However I was never able to get it to work in my gun... The same gun ran weldups made for me by Jim Anglin and Fred Craig with no problems. I suspect it could be tuned to work I just didn't bother at the time since I didn't need to. I have a gun built on a first gen frame (round trigger guard) if I can find the mag and remember I can at least try test fit for you if that's helpful? I use MBX mags in my STIs and they have generally been fine. One day when I get a chance I'll ping Adrian and see what his thoughts are (when he was staring out making STI mags I had one of his mags that wouldn't work, after talking to him he sent me a redesigned follower and spring which made it work like a charm so I don't doubt this can be made to work too.)

hdgun Posted January 26, 2021 Share Posted January 26, 2021 I have 2 gen 1 frames. Both needed extensive opening of the inside grip. Mags were super tight. 2nd gen no problem. Link to comment Share on other sites More sharing options...
