I've collect all these in the 4 years I'm playing airsoft, things are becoming tough economically so I won't be able to buy like I used to...
I'm using all (except th SP M40XB and the SG Barrett cause they're not ready yet!) but for target shooting, I've played with most of them.
I've used the Asahi WA2000 but since it's stock the range was pretty bad ( max 60m effective ~40m), it doesn't have a hop up installed yet. I've ordered an SCS barrel for it made by SniperX but USPS lost it!!! I'm waiting a new one but it's not ready yet! I intent to use it in some short and special games!
I WON'T USE the Asahii M40 at all.... This is for target shooting only, I can't say more cause I haven't been able to test it yet due to pretty bad weather, more for that at an up comming review!
I bought the Sun Project M40XB used and broken! I managed to find the spare parts for it after a lot of effort, the gun is ready but I can't find magazines for it! So I'll modify it to accept properly APS2 mags!
The SG Barrett has been completely stripped from ALL internals I'll use a 800mm 6.02 Deep Fire barrel with Systema bucking in a Promytheus Strike NEO hop up. I'll use the PolarStar Fusion engine with it but due the bad SG design I can't mount the engine properly!
This is the gun with the engine installed..
I'm waiting P* to find a way to install the bolt handle/hop up cover.
The base for the bolt handle was attached using the 4 screws at the top of the stock GB, Fusion engine doesn't have the screws simply because it doesn't need it!
P* told me they will find a way to fix this!! I'm waiting an answer from them!
This is athred about it:
