this is my first post here so i hope this helps and if you want i'll try to get pics up to show you what i did . i got the new grip today and after like an hour (had trouble disconnecting the gas line from the old grip an putting it on the new grip)i finally put the handle on the marker and no, it does not accept the lapco air through mag but with some minor modificationing i got it to accept the mag (i just ground down the sides inside that fits next to the trigger guard) works like a dream (now i just gotta find a way to make it left handed safety with the safety switch on the right side of the marker an me being a lefty it really cuts into my trigger finger when its on full auto so warning the other lefties) and yes the Rhythm Innovations x7 trigger does work with it now just waiting for that A.P.E. board
