DodgeNerd Posted March 27, 2022 Share Posted March 27, 2022 Quoting; "CHA-LEE Posted November 14, 2018 File the bottom of the barrel feed ramp flat so its even with the frame when the barrel is in the "Down & Back" position sitting in the frame. Doing this will also minimize the chance of the bottom edge of the ramp gouging into the tip of the next bullet in the magazine. To me this is barrel fitting 101 that a competent gunsmith should already know and setup properly from the start." So I'm a victim of the mbx mag being dented by my barrel. Does anyone have a picture of a "fixed" barrel fitting as an example so i can compare (before I possibly ruin my barrel)? TIA Link to comment Share on other sites More sharing options...
donnyglock Posted March 27, 2022 Share Posted March 27, 2022 Man that’s not even close. Your gunsmith definitely should’ve done a better job as everyone is using MBX mags. I can machine the barrel ramp for you if you want. Link to comment Share on other sites More sharing options...
Bravo_Victor Posted March 28, 2022 Share Posted March 28, 2022 I had to reshape my MBX magazines bc both my guns would hit that same spot. Link to comment Share on other sites More sharing options...

Is it possible the mag catch shelf on your mag release is too high. Some shelves are .020" higher than mil spec. All of mine are .010" higher and work with MBX mags.

ltdmstr Posted March 29, 2022 Share Posted March 29, 2022 Here you go. Doesn't have to look exactly like this. Just move the vertical flat surface at the bottom forward (toward the muzzle end) so it doesn't overhang the inside of the grip. If you look where the bullets are hitting, it's probably 1/2 inch above the area he needs to move forward. So removing .050" is not going to make any difference in terms of feeding etc. Link to comment Share on other sites More sharing options...
Brazos Custom Posted March 29, 2022 Share Posted March 29, 2022 Chamfer the bottom edge of the barrel ramp a little and roll the right edge a little and then take a little off the high spot on the magazine. I like having the ramp as far to thee rear as possible so that the nose of the bullet contacts the ramp as soon as possible. Link to comment Share on other sites More sharing options...
texasdawg Posted March 30, 2022 Share Posted March 30, 2022 I have three 170s, two 140s, and a 155 MBX's. Two of the mags were showing a little ding on the front edge where they were hitting the barrel feed ramp. I took a cratex tool and knocked the dinged spots off the two mags and touched up the bottom front edge like described above. Haven't seen any more dinged up mags,,, Link to comment Share on other sites More sharing options...
