Airlines finished, now testing the magazine feeder setup, some issues but nothing I can't fix. Test firing at 90psi went straight through 1/2" plywood :shock: was not expecting that :D

more spring tension on the loader arm then had to add extra spring to close the 'bolt', a small profile change to the ammo pusher edge and the bolt tube edge as well and it seems to work smooth now. Only a 2 second video so you might want to play it in slomo.

Almost finished now, need to make a catch to hold open the spring loaded arm on the magazine so I can load it easier, move air inlet to side as it gets in the way on the bottom when you put it down, and make a stand to rest it on and hold it upright when shooting, sort of a bipod/monopod thingy, it is shootable from the shoulder but it's pretty heavy.

Made and added a forward assist lever for chambering first round, works really nicely :lol:

Lazer pointer and 1913 rail on sight

Time so far I would guess at 200 hrs, cost $10 for the 1913 rail and the laser pointer, the rest was free :D

Used that piece of 1/2" MDF to shoot at and it goes straight through at 100psi. :bounce: now I need to build a target that can safely catch the BBs :idea:

Once again, fantastic job! Are you thinking of painting a uniform color? Seems almost a shame...

No,I'll just let it shine 8)

Might try some open sights on it instead of the sight thingy, it really has no function :?

I'll post it in the showcase when I'm happy with it, with dimensions and weight etc.

Side entry air

Au naturel is best :)

The problem with the sight is the tiny radius, front and rear sights are too close together for meaningful accuracy.

Pretty sure you can fit a little cheapo Chinese holographic sight in that shroud...

It's pretty good how it is now, moved the pointer to below the barrel where I originally intended it and set the sights and pointer up, fired 3 shots at 14' and wondered where 2 & 3 went until I realized they went through the same hole. I think it's time to call it finished and move on to the next one, single shot 6mm airsoft with 3/8" QEV, 400mm barrel. Going for simple and light weight. MP5 sort of scale.
