Installed my Magguts system yesterday, took only a few minutes then went to my sons to put a few mags through it. I put the following:
7+1 Federal Hydra Shok
7+1 Blazer Brass FMJ's
7+1 Hornady CD
Ran them as fast as I could run them through and reload. All 100% no hiccups just like it was suppose to. I did notice the very first time I put a full mag in it did seem a little hard to lock. I popped it right back out and in and it seem real good nothing like the first time, went in with very little pressure. Maybe the springs just needed seeded just right. I am very happy with the system and will keep it. I really didn't feel a need to run anymore as a test as it ran so smooth and natural plus it was raining some but plan on running a box of Blazer Brass FMJ's through real soon .
