I've got a couple of these coming in for my Glock and my M14, once I get them installed I'll offer my impressions, although they won't be nearly as in-depth as Illusion's research.

Kurgan, the easiest way to get them is to get in on a group order to WGC or UNCo. I ordered mine in a WGC order with Raygis LasVegas.

So...

How much and when can you ship to me? (TM M4 Length) :D

Have no range time booked. Been pretty busy with work.


They've all been sold since then. :D

The range test will actually take a fair bit of time. Each added variable multiplies the number of trials to be run. We also want to do a fair bit of other research if we're going to go through the trouble of setup:

for example:

-ten shots per unique setup
-4x AEG spring setups (~stock, ~330fps, ~380fps, ~420fps)
-11x total barrels: 4x M4 barrels (stock, TK, PDI 6.50, PDI 6.01), 3x M16 (stock, TK, PDI 6.01), 4x P90 (stock, TK, PDI 6.05, PDI 6.01)
-5x/7x total bb types: Maruzen 0.29g Grand Master, 3x Guarder (0.2, 0.25, 0.28), Excel 0.2g, for only one B/A setup: Straight (0.36, 0.43)

That limited but generally comprehensive results in 220 unique setups (the b/a tests on heavy pellets is not to be done with AEGs). Those 220 setups will require 44 gun unique gun configurations (swapping barrels + springs).

I'd also like to do some tests with a very high energy setup to measure actual pellet velocity at different ranges so we could finally come up with a well informed decision on safe sniping ranges and acceptable mercy range. Truth is that if we're willing to accept a closed ranged hit from say a 300fps AEG firing 0.2g pellets and said pellet decellerates to 280fps in 10', then we should be willing to accept no mercy rules with a stock gun game where only 280fps guns are in play. We can also use the range-speed data to determine practical safe sniping ranges for high energy rifles.

220 unique setups require 2200 carefully aimed pellets on paper. That works out to a heck of a lot of time changing gun configurations and targets. A useful range test is going to take a lot of time.

When these tests are done, I’m going to have to look into this.

My WA Beretta’s got great range on it, but it could perhaps use more, so could the FA-MAS if there’s a particularly long barrel available.

my current setup curves a bit to the right. Would this fix it?

Doing tests with a ba and straight pellets isn't the best. Yes they are heavier but for a loss in quality. The straight pellets are the pits. I had a bag and at 500 fps my ksc .3's and guarder .28's faired better then them. Consistency goes out the window with the straight pellets washed or not.

No, unless your current barrel is warped or carries some kind of burr that imparts the hook on your BB.

Dunno how safe the following advice is. When my G36 shoots a bit to one side after reassembling, I just grab it by the inner barrel and give it a firm but really minimal twist in the opposite direction. Fixes it right up.

update: I dropped my rifle. I had in on my shoulder and the top sling hook came off and the gun rotated down and hit on the muzzel.

Gun shoots better now.
I invested in a better sling since then and have ordered a twist barrel to see what it does myself.

Where'd you order it from?

I ordered mine from WGC through one of Raygis LasVegas's group orders.

I've got them now, just waiting on a chrono.

what he said

K, ILLusion is getting one for me now.

ill be reciving a 509 mm tanio koba barrel, and putting it in my M170 tuned rifle on FA, with around 24 RPS. then we will see if they are truly unsuited for high fps upgrades. som guys in denmark thinks they are fine for fps over 400 also, thats why i want to try this, to see if they are right since mine are around 578 fps. i will be reciving it around the 14th, and trying it out in a game the 28th, i wont do any target shooting only real testing. to see if the bullet trajectory is screwed or if it is level.
