I have been searching for a bolt hold open device to hold the chamber open apon firing the last fired round from a magazine to no luch for quite some time now. I have posted in several forums including AR15.COM regarding finding this device and no one seemed to know of a source to purchase one from.
Well last night on SAIGA12.COM in the forums section theres a gentleman thats an engineer that sat down on the CAD and designed such a device and has made several prototypes including the one he has on his AK now and claims it works perfectly. He wont post pictures of the device as he has a patend pending but explains the design in detail.
Hes talking about selling the device for around $100 and gave a description of the contents to the kit as he expects to ship it out, but isnt excepting orders as hes still looking to perfect the design a bit more... damn engineers, cant fix what aint broken, just let us get it if it does in fact wok lol
