A fantastic SR-25. It has fantastic potential. The body is wonderful with no wobble a great feel and is just robust. Internally it is no slouch it has held up to plenty of abuse and the parts comparability is pretty good. I look forward to upgrading it to see how far I can push it.
Pros:
Upgradeable
Fantastic body
Cons:

Solid gun.
Huge battery compartment and it's easy to access too. Battery compartment on this gun takes Small Tamiya plug-type batteries. If you're trying to run a battery of a different plug type (including Big Tamiya), you'll need an adapter.
This SR-25 comes with a high cap mag, a Picatinny rail compatible vertical grip, and a compatible suppressor.
Mine clocked in at 385 FPS with .20 gram BBs so I'd say the FPS listed in this gun's description is either incorrect or outdated.
Anyway, most players' rifles at my field do 330 to 350, so with this being above that but below 400, the field I play at allowed me to use this SR-25 at all distances (CQB, mid, and long).
Fire mode selector and safety are on the left side. Mag release is on the right. This is not an ambidextrous weapon platform. This SR-25 is for right-handed shooters like myself who select the fire mode with their right thumb, look down the scope with their right eye, and release magazines with their right trigger finger.
This gun has a full auto option but your field will likely require you to "semi lock" your SR-25. There are MOSFETs that can help you do this as well as other methods (YouTube helps).
To get this thing at or above 400 FPS, you'll need a more powerful spring. Good news is, that'll only cost you like $10.
You'll need a good hunting scope with a variety of zoom settings to bring out the full potential of this DMR.
The SR-25, in general, is not designed for CQB. You will need a sidearm while using this. Ideally.
This thing is roughly 15 to 20 pounds once you have it kitted out and have a full mag inserted. You will need to (1) get yourself in shape enough to carry/maneuver this thing for hours at a time and (2) get a sling so you can conserve energy while using this rifle.
Pros:
Full metal
High cap mag included
Vertical grip and mock suppressor included
Lots of rail space (can comfortably fit a grip and a bipod on the lower rail).
Great performance right out of the box.
Already wired to Small Tamiya.
Has plenty of room in the battery compartment.
Battery compartment is easily accessible.
A&K high cap SR-25 mags fit securely and feed well.
Cons:
Stock has a tiny bit of flexibility. It's not loose or wobbly. It doesn't wobble down and up, but it does allow a few inches of left or right give which is somewhat useful if you need to change your position slightly in a bi-pod mounted position. To others, this detail may be a problem.
Not sure if that's intentional by ACW, but just wanted to share what I found.
-Very challenging to aim down a scope on this gun while wearing an airsoft mask/helmet. You'll need to buy a riser which allows you to have your scope attached at a raised position.
