I see that xn has updated their website. Looks like the collapsable stock is now standard. I wonder if these are shipping yet. http://www.mkaarms.com

Good deal, i'm definately upgrading. Thank you guys for the the information!

Hello to all! I'm a new owner of a mka1919-xn. I just had a quick question for those who have upgraded to the S6 foregrip. The website says to install a shorter guide rod. Does that affect the operation of the firearm at all or is it business as usual once it is installed? Thanks!
