I can't be the first to do this. Honestly this was the easiest build I've ever done. I happen to win an auction on Ebay for a cheap 90* 05/06 Angel frame w/ trigger. A quick drill for a new front hole and a trimming of sear and here we are:
Only shot it a few times with the little air I had left in my scuba tank. I just got it refilled so I'm going to try some paint through it to see if I need to adjust anything, but so far it was almost drop-in ready. The only problem is that after I took the photos I decided to tighten the grip scews a little more and cracked the top right of the left grip. Doesn't look too bad, but it was a stupid mistake. Thanks again to Runamok for the killer deal on the grips. Now I just have to find a 45* Angel trigger frame to do the same mod. I think I like the look of the 05 Angel Gat trigger frame better then the 90*.
So I messed around with the sear, on/off and vert trigger frame and I think it's where I want it to be. I might go back to my ULT cause I never really liked super RT-ing mags, but the bounce from this trigger frame really is awesome and controllable compared to an I-Frame. I had to drill out the trigger some more to make the sear rod hit in the right spot. I'm going to pick up an extra Angel trigger as a back up.
The next "upgrade" I did to the mag was put an Angel 05' reg forgrip on the Shadow rail. I've always loved the simple look of the Angle reg so I picked one up for cheap on Ebay and gutted it. Matched up pretty well except it's dust black instead of gloss black. To top it all off I put a newer Angel clamping feedneck on the ULE and now it's fully a 50/50 Angel Mag. 3x AGD parts and 3X WDP (Angel) Products.
Might called this one done unless I can find an Angel barrel that is cocker threaded. lol
