The Karta accepts:
WGP Autococker compatable barrels
WDP Angel compatable feednecks
WDP Angel compatable ball detents.
Any AGD trigger frame
Any AGD valve except the RT-Classic and Sydarm
The Karta body kit includes the Karta aluminum mainbody, Karta sculptured Emag or RTPro rail, and dual AGD (WDP Angel style) ball detents.
For $20.00 extra, the rail can be ULE ("Ultra Light Engineering") milled to shed another 2.4oz, bringing the Karta's rail weight from 5.5oz down to 3.1oz! The Karta body alone weighs 4.1oz.
All ULE rails now have the foregrip slot standard.
We give discounts for Slug and rail "trade-ins". Please see below.

It took some bribing(yes, $$$) to get Colin to go back to the drawing board and recreate his machining code so that these could be done. The Chord v2's have been in the works since the summer! Anybody that has sent Colin a Slug knows that these things take time. 
For those who arent familiar with the Chord, they are the ORIGINAL mag Ripper style body, and arguably the best. Machined from an authen...
Thanks
