WE Desert Eagle (Licensed by Cybergun)

Got some chrono readings for ya'll!

 

Did two chrono sessions with two full magazines worth of gas. Let the magazine go back to ambient room temp (2-3 hours) between tests.

Shot count and high FPS differences are probably due to magazine being in different places in my apartment when going to ambient temp between tests and not filling the magazine with the same amount of gas between tests, and it being a brand new can of gas.

 

Pretty impressive consistency and average both within each session and between the two sessions.

WE exploded view image is now working and higher resolution than KY Airsoft.

BTW I recorded my slide disassembly and reassembly video today and I could not get the front sight off. Tried some different tehcniques but decided to leave it be.

I did, and I tried, and it would not come out. I pushed it down all the way flush, pushed both ways. Pushed it down on one side, tried driving it out the other, and then to the other side, and I pushed it down and applied force with a punch, pushed it down and wiggled it while trying to move side to side, etc... And it did not come out.

 

Even if I did get it out, I am worried about getting it back on again :P

 

Also FYI I fixed the loose rear sight fit with a couple of layers of aluminum tape on the BBU nub that seats in the bottom of the rear sight.

It's really tough to push out. But it's important that you keep it pushed down completely otherwise that bearing wedges itself between the two making it impossible to drift out. Pushed mine from right to left if it helps but looking at it closely it appeared to be symmetrical.

I took the liberty of enhancing the WE exploded view image a little bit. Removed the WE logo from the background, added some thicker and sharper lines.

Ha. I had a feeling that was a silly question and that you just free handed it with something requiring considerably more skill.

Just a small update. While I widened the hop window right after I got it to provide more hop (as I do to all new WE guns), I found accuracy to be lacking. Grouping roughly 8" at 20m my Makarov does better even with the suppressor off. I was examining the barrel and noticed the roughly machined crown so stuck it on my ghetto lathe (power drill) and proceeded to clean it up: refaced the front edge with a file (was kinda bumpy originally), sanded and polished the deep chamfer to a mirror polish (had a ridged pattern presumably from being turned). Surprisingly enough, it shrunk groups in half! Will do some more extended testing as this now appears to have the potential to be a viable sniping handgun.

I remember rebuilding a really ancient TM M4a1 for a friend on a budget which effectively only covered a metal receiver, rail and outer barrel with minimal amounts left over for internals. I ended up cutting down the stock TM inner on a lathe before recrowning it and giving it a quick polish and it's pretty much on par with the Madbul black 6.03mm tightbores everyone used to rave about a few years back.
