JT ER2 with spring feed

Thought I'd share what I'm working on with a JT ER2 I picked up. Nothing super special just removed the feedneck and added a rail to mount a BT spring feed. I have a nelson spring kit on the way to lighten the pump draw, and eventually I want to get and mod a smaller bore barrel to give better efficiency and a little more barrel length. I'll finish it off with an fde paint job.

No velocity adjustment except swapping springs.
Mounting the spring feed required removing the feedneck and carving out a bit of the body.
The spring feed is made by bt for the trracer, the rail from a 3 pack made for an airsoft g36. To mount the rail I drilled a couple holes for screws sized to the rail holes while the shell halves were together. There is an empty channel inside the shells in which I glued a couple hex nuts.

I can get pics tomorrow if you want, just painted it.

You can heat up that barrel and shove a freak insert into it. Worked with mine.

A heat gun, which is just a very fancy hairdryer. Could probably get away with propane torch.

This is the area of removal to fit the spring feed.
