Running comparisons between the G3's and G4's and the G3 definitely have more power being closer to the chamber. This allows us to de-tune when running soft loads which I think is a big deal. Putting different hand guard options together and seeing how things look. I'm going to try a hybrid G4r2 in the G3 position, again. It didn't work the first time but it has to work now with the other advances we have made. If that gives us the room I need along with the power, it will be the best of both worlds and will be the one we run with.

Ran a few hundred rounds of the light loads through G3 last week without issue and tried again today. Got some nose up jams and some short strokes so time to pull things apart and see whats what.

Assembled and tested G4r2 with success. This is the version we are going with. There are going to be two of them we'll do, G3r2 and G4r2. We are going over design for mfg today and will get a block of them on the machine for initial production. At some point we just have to do it, right? I'll work on pricing to get these first ones out and start taking pre orders.

This project always is the one that gets put on the back burner........ But..... working on a different upper that needed some more hand guard room I finally just said "screw it, just build the dang thing!" Now that Big Ugly is done, we'll get to the refining stage.

Been tuning on the piston set up ans its running factory UMC 115gr just fine. I swapped out lowers this morning and set it up on the New Frontier polymer lowerand its running ok on it. Ive got two coffee cans of reloads bro did for me but they are too light to run on this G4 set up. G3 runs them a bit better so we should be able to duplicate that performance. The factory loads clocked out at 1340 where the reloads only hit 1250. the new 9 blowback dropped 30 fps over the piston, but eats anything you feed it. Maybe ill bring the carbine out tomorrow...

Back at the shop and have my real 9mm loading set up so going to knock out a bunch of "factory" loads. I tried last week with my .38 Super dies, but it didn't work with the 9mm brass. The piston has been kind of the orphan child since I've been on the road so we'll see if being back gives it some more attention...... got to have ammo first....
