decent iTrader feedback, will accept Money Order or FTF in Los Angeles Area (Marina del Rey). Thank you!!

This is the best mag block for a AR 9mm setup that you can buy.
Selling one brand new, never used, bought it then changed my mind about completing a 9mm project due to financial matters. Please buy mine, also I will soon be posting a 9mm CMMG BCG, 9mm spikes upper, 9mm 5" heavy barrel



Designed for quick caliber change between 5.56mm and 9mm with minimal effort. Adapter loads in from the bottom of the magazine well and secures with a tension device. Ideal for users using Colt magazines and frequently changing between calibers that desire the bolt hold open feature. Holds the bolt open on the last round with Colt magazines.
