Worth it?

I've been looking at the STAG-15 M8A3. It's basically everything I want/need, but I've been looking for full-metal guns around the same price.

If you would like to suggest one, here's the criteria:
- 390-410FPS << Important
- Scope rail, iron sights, and at LEAST a bottom RIS handguard rail (important)
- Less than $300
- Full metal is nice, but not req'd
- AR15, SCAR, G36, anything that is NOT a CQB-purpose weapon, and I don't want an AK

I don't want anything less than the above standards. Here's what I don't care about:
- ROF
- Magazine capacity
- Manufacturer (as long as you don't suggest a notoriously faulty brand)


Thanks
EDIT: Nevermind about the SIG, I edited it out of my post.

I'd get the m8 more upgrades possible

I just found another.

I have heard mixed reviews on the A&K SR25 + it is out of stock, and it has been like that for nearly a year. D;

Now I actually have the Stag 15 and it is your usual Echo 1. One con I must point out, is the stock barrel length goes to the end of the RIS, not to the flashider. Replacing the barrel is a upgrade I recommend out of the box.

Alrighty then, I guess I'll just stick with the STAG.
