During a match in june, I was finally able to figure out why I couldn't load a round in when I had forward pressure on a barricade, in that my magazine was moving around in the magwell and causing rounds to bind when feeding. I looked up how to adjust the magwell but the adjustements that are in the instructions and on the website didnt really allow for anything on my chassis. I ended up using the tolerances of the plastic modled pieces between the magwell to tighten it up a littl bit, but no where near as much as the instructions say one could. I ended up using a MariTool Conversion card thats .0225 thick and cutting a small section to make a shim for it. Tested my MDT Steel 10 round mags and they were pefect. Here's where my problem starts. I just asssumed my 12rd magazine would fit just fine. but come to find out I have to press it in crazy hard, and to pull it out is just as hard, if not more. Any suggestions as to a resolve that doesnt include removing material from plastic parts? I have kind of conceided and bought a +2 extension, but it would be nice to have a 12rd magazine that fits.
