I want to buy any of the 3 listed above (or similar gbbr) with 5 mags if they hold 30-35 or 4 mags if they hold more.

I don't mind about upgrades, internal or external, however I currently have quite a strict budget hence a lot of the stuff on the market is too much due to their upgrades.

Please message me whatever you have and I'l consider it!

I'm from Southampton area so can collect if an hour or so away.
