Yea, I noticed that on a couple of mag changes I ended up hitting the foregrip with the mag (I'm new to AKs and Rommys, but used to run a Mini-14 back in the day ). I realized that the mag only needs 1/2" or so of pivioting to allow it to be pulled down and out of the receiver.
I am moving the forearm (in the above picture) to build number two, a copy of a AIMS-47 (WillysWagon is partly to blame for that :mrgreen: ). Since this picture was taken I have replaced it with a Rommy G handguard that I cut down to a AKM profile. Not much wood there, and I tell you she gets hot fast.
