G&P High RPS Polymer Training Magazine w/ EV Texturing for M4 Airsoft AEG Rifles (Type: 130rd Mid-Cap / Black / Single)

"I can only get about 60 rounds in mine and they don't AT ALL feed. I silicone sprayed and tried to break them in but no difference. They even jam on the last 5 rounds where the spring is bearly compressed. I have the high capacity versions and I love them. They are light weight and don't wobble in the mag well like most Stan mags. But the mid cap versions I received are an absolute waste of money.

"I used these mags only twice so far, and they already broke down. They wont feed at all anymore, or just barely. I did do maintenance and even opened them up to see what could be the issue, I cleaned out everything. Even lubed one up with a little bit of silicon oil. And they just wont feed anymore, Also the quality inside these mags are terrible. Would not recommend.
