As an owner of a T68 Gen6 marker, Im always visiting the rap4 site an rap4's forum ... must say these D-mags are a WELCOMED addition to the rap4 product line as $5 ea mag for the D-mag is far better then the $37 ea rap4 T68 mags currently available. As far as these conversion kits go ... a LOT of the questions being asked here are answered on the rap4 forum ...
where does the airline go, is it behind the magazine or at the base of the Stock (there is mixed info on the web)? ... There is a flexi-air buttstock kit for your gun ... found here http://www.rap4.com/paintball/store/...-air-buttstock
Does it support all rap4 Magazines as well as all RAP4 magazines (are there any magazine i should not purchase)? ... Yes, the mag conversion kit accept ALL rap4 68 cal magazines, in regards to what to stay away from, that would be the older styled feedneck on the mags .... but I dont think u can buy them anymore so u should be good. HIGHLY RECOMMEND the new D-mags as u can now shoot first strike with these mags
what is the thing (all the pictures but the grayed out one - http://www.rap4.com/paintball/store/...-paintball-gun
) that is between the trigger and magazine and is this not included in the Kit? From what I can tell, you are referring to a part of the kit that covers where your air intake used to be ... if it wasnt included there would be a gap between mag well an trigger guard throwing off the overall appearance ... yes, it IS included
to best of my knowledge
is the hopper breach designed for First Strike (so i could manually feed single rounds)
a picture of the other side would great to see (all the pictures i have seen where shooter's left, no right sides)
I dont believe you would be able to load rounds one at a time through the breach ... the mags them selves hold the rounds and 20 of them ... be it regular 68 cal paintballs or first strike rounds. You can load one clip with first strike rounds and other clips with normal rounds and dont forget about the ammo box mag that loads like a mag ( from under the gun ) but holds 250 rounds ( of normal 68 cal paintballs .. not FS compatible ).
I answered the questions I knew the answers too, and double checked my answers on rap4's forum before answering ... hope this information helps you guys out. As for me .. I bought a mag kit for my tippy 98 and soooo cant wait to get it
