2 magazines SPF, 1 AR and the M249 are available. Shoot me an email if interested. Yes, I do take PayPal but I ask that you cover the fee.
3 M16 Beta CMags in new condition. here is the deal: they started life as M249 drums. I replaced the towers with new M16 kits. One has had the LEO markings removed and painted black, another had the same done but only the covers painted black while another is untouched. NO accessories but they have a dust cover and graphite lube (2 tubes each). $175 each. I have another that is a M249 drum. The only difference is the tower. Same drill (no accessories), body untouched, $150 so you can afford to come out after buying the $25 tower. You can modify this tower to work (just like the Izzy mags in your BM) but it will hang low as the 249 tower is longer than a 16. Buy all 4 and I'll go $600 on them and cover shipping (you save about $90).
