M4 style open bolt mags are the same for the SCAR and the PDW. Its the same mag.

Will you be planning on getting your hands on some of those kits and/or the full thing when they will be available?

I plan on getting every product I can to improve my inventory. I can easily aquire the Scar open bolt kit, but no clue as to getting open bolt SCARs yet.

Well, update to my scar. It turns out that the open bolt kit is just as powerful as co2. After 5 mags fired through my open bolt scar, part #027 blew up and my gun fell apart into three pieces. No one makes reinforced replacements for these which is really disappointing. The only way to get a replacement part at all is to convince a retailer to order it from WE themselves. We will just ignore your emails if you ask them directly. And ra-tech won't talk to you unless there is a decent amount of money involved. thank god for amos.
