Sun Project XM177?

[Raptor]

So hence the name of the thread, someone is offering me a Sun Project XM177 and really never heard of Sun Project. After doing a little research on the interwebz and not coming up with much of anything im wondering if any of you could give me some info on these things like realiabilty, can I use HPA, should I even use it, and anything else thats important.

Admins if in the wrong spot please move it to the correct.

Sun Project rifles are classic airsoft, made in the 1990s. You can probably find more information on Classic Airsoft Dot Org. Here's a video from Redwolf on a Sun Project XM. Here's a review of a Sun Project AR on Airsoft Canada.

It's be a while since I looked into Classic Airsoft rifles, but my understanding is that you can run HPA using an air-rig designed for a Polarstar.

From what I recall some Sun Project guns had fixed hop-up while others were modded to have adjustable hop up.

Good luck with your research.
