I have for sale (or interesting trade) a 'Lightning Bolt II' (2nd generation) tactical ambidextous charging bolt carrier with piston attatched (bolt assembly not included). It slides directly into almost every AK-47 variant. It was developed in Colorado by a company wishing to make mag changes more fluid, shaving time off of the reloads and eliminating some of the awkward movements changing magazines. It sells for $275.00 and comes with an attached piston and modified dust cover. I have 2 of them and would like to get rid of 1. Please educate yourself as to its positive addition to your AK platform (type 'AK Lightning Bolt II' into YouTube and watch the vids). I would love to trade for some nice 7.62x39 ammo or a used $200ish tactical 12g pump...or if you have something interesting in the same realm to barter, let me know. Trades? Ideas?
