Heya gents. 

After a full set of PTS EPMS, so the N-Types have to go. 

These are Variable Midcaps with very good springs out of the box. I bought these 2 years ago brand new from the now defunct Pro Airsoft. I only ever used them testing at home, two skirmishes and only when my High Caps ran out. So almost no use, Some minor marks on the mags where they have been inserted into the magwell, but otherwise very very clean. 

I used these in my TM KSG with M4 Adapter as they have the power in the springs to keep it feeding unlike many other midcaps. 

You can change the capacity from 125rds to 30rds with no tools. Slide the bottom plate off and adjust. Springs are easy to access and replace, again with no tools. 

Patrol base have these for £11 a mag. Buy these practically unused ones at the equivalent of £6 each, pickup in London preferred, postage will cost extra. 

Cheers!
