Last night I got this trigger group sorted. This is a direct full-size micro, it travels about 1/8", feels like an arcade button, and is by far the best trigger I have ever done. I used the stock Rayven trigger and cut nothing, and the switch body is backed against the inside of the grip. Trigger travel is restrained by a piece of PVC in front, since this was a semi-auto the stock travel was too far forward.
Begin day 2 of the build, January 1, 2015. I picked off most of the plastics fabrication chores. Here's what it looked like before, notice the carry handle went missing.
Cheek rest area had a large hole to patch.
The removed carry handle piece with rail:
And the plan:
This shroud rail is superfluous. Well, I'm not just going to leave the damn thing there.
Perhaps I will leave this hole, though. Barrel shroud ventilation hole under the carry handle?
Base of the new front carry handle standoff:
Blurry image, but that follows the receiver angles
Devcon carry handle to old front standoff, now new rear standoff and rear sight mount:
Mock up new standoff pieces
Finished carry handle/top rail install
Needs some trimming and sanding of those rough standoff pieces
Result
Started dealing with old grip situation
Fabricated stock/buttplate. 2" Schedule 40 pipe into sheet. Thick and solid. Grooves freehand with grinder
Replaced that missing side cover with a PVC one
Side view of all that.
Mocked up battery position. I considered locating the pack above the pusher box as well as under the stock area, but that was all wrong for weight distribution, not to mention tight, and in a way, this is not a "clean" build. It's a quick and dirty secondary rig. It's not a Tacmod and it will never have perfect balance and handling like a Tacmod and I didn't want to build it a custom pack or deal with charge connectors. And I had this 2S 1600mAh pack already, so done.
I will be getting nowhere on this for at least a week while I am away from Site B, so here it stands.
To do:
Motor endbell covers
Front grip addition (to hook the support hand like a P90 to avoid getting it in front of the muzzle)
Muzzle device - suppressor?
Mount and time cycle control switch
Install screw and shape front of magwell
Fence magwell
Patch hole in heel of grip
Bondo/Sand/Paint
Install FKs
Wire
Wreck Rayvens!
