My research on them
Masterpiece arms makes a good semiauto mac varient.Dealer price on them is much much lower than 310 bucks.Some ffl holders will order it 10 bucks plus shipping over cost.
the 45 acp version resembles an original ingram mac externally,its bigger,fatter and significantly heavier than the 9mm m11 version.It also uses unmodified ww2 greasegun smg mags.
The 9mm varient is exactly as pictured in the above post.These use unmodified ww2 sten smg mags.
Both versions have either a top cocking knob or a side cocking knob.Theres even a mini version out thats half the size of the m11.The main difference between the MPA copy and others is a redesigned bolt and everything is cnc machined and heat treated plus the cost is significantly lower.
rats! I almost talked myself into getting one and at this point, I cant afford another toy.
