We went on a long research project on whether he could use a Galil Ace PDW in 7.62x39 to challenge the utility of a 300blk PDW like a SIG Sauer MCX Rattler.

While the 300blk is a formidable PDW that can essentially cover 0-300 with super and sub sonic loads, the 300Blk cartridges can be difficult to find outside of North America... so a 7.62x39 that can duplicate the 300blk's performance could be the ticket... but could it really?

The real question was how to adjust it's gas EXTERNALLY to accommodate super and sub sonics while also being able to to use a suppressor...
