Tm Hicapa Mags

[isaacgowling1721]

So i own a TM Hicapa and i brought a bunch of TM Hicapa 5.1 mags. Since ive had them they've never feeded properly to the point where BBs get jammes before the reach the lip of the mags leading to dry firing and inconsistencies in the field, which as you can imagine is pretty frustrating. Ive tried cycling gas through them and lubing the mags with Silicone lube and ive tried stretching out feeding strings slightly nothing works

ive seen this be a fairly common issue with many mags but none of there solutions have worked for me so far so taking any advice i can

If it's stopping at the start of the bottom of the lips sounds similar to a common clone mk23 mag issue. Check the transition between the feed to the lips. Sometimes the slightest step between can mess it up. Careful reshaping shaving with a sharp blade will fix it if it's that.
