The review below is made by EL GUAPO from
www.bbsdepot.com. Ill try to make my own review soon. I'll add up my own GR25 pictures as well.
EL GUAPO's Review:
Alright, I have been away from the Airsoft GI Forums for some time now and I thought that a good way to jump back in would be to write a review on a gun I purchased quite some time ago, yet seems to be lacking any reviews. This gun is the G&G GR-25 Sniper Rifle.
The G&G GR-25 sniper rifle is a replica of the Stoner Knights Armament SR-25 sniper rifle primarily employed by Special Force units it fires a 7.62 round and is one of the most accurate semi-automatic sniper rifles on the market. Not to mention, it looks AWESOME!
Real Steel SR-25
That is about as much as I am going to talk about for the real steel version.
The Airsoft version made by G&G is incredibly faithfully reproduced is similar engravings, same body shape, and receiver size. Let me first start off by explaining what makes this rifle different from other adapted M16's or M4's to act as a Sniper Weapon System. The SR-25 is chambered for a 7.62 round in real life as opposed to the 5.56 of normal M16's, and this is true in the shape of the GR-25. The GR-25's receiver is an expanded version of an M16 receiver giving it a much longer magazine well, slightly larger trigger guard, and a generally bigger feel. Unfortunately, this is a problem when you are out in the field and run out of ammo in it's shrunken magazine, you magazine well is too large for normal M16 magazines. That isn't saying you can't still use them, you will just have to hold them in with your hand as the magazine catch will not hold them in place. Otherwise, the larger receiver is a plus in my opinion, allowing the manufacture to really put in a much detail and attention to the rifle as possible, and G&G sure didn't dissapoint. The only other downside on the receiver is that G&G didn't use the authentic Stoner logo (which is not a surprise at all, but would have been an amazing touch). The gun is laser etched so the durability is fantastic on all of the engravings. There are two modes the selector switch can fall on: Safe or Fire. Yep, thats right, this M16 Frankenstein behemoth can only fire in semi-auto. Which, when you think about it, really isn't too much of a draw back for be a sniper rifle, semi-automatic is an awesome ability to have. It comes with a standard M16 grip which is textured nicely for a good hold and feel (I replaced mine with a SPR heatsink grip, which is a GREAT addition). It also comes with a 50 round standard magazine (imagine a Vietnam style magazine for an M16, 3 inches shorter). The charging handle is well made and unlike some TM and CA guns, the spring inside is a completely separate part of the gun with its own spring guide, making jamming or tangling of the spring a thing of the past. Probably my favorite feature of the G&G GR-25 is the charging handle and the dust cover. When you pull the charging handle back on the rifle, not only does it open the dust cover allowing easy access to the hop-up unit, but it also goes back to the full length that a rifle's charging handle should! Also, when the charging handle is pull back, the bolt catch works exactly as it should, locking the door to the hop-up open, allowing the charging handle to be returned and still maintain access to the hop-up. The magazine release is just like that of a normal M16 and works flawlessly, never had I had a problem with it keeping magazines seated properly in place causing mis-feeding of BB's. The last part of the receiver I'll talk about is the RIS rail which will also lead us into the next portion of the review. The RIS rail that graces the top of the rifle is sturdy and is part of the upper receiver itself which means no flexes or chances of falling off (like a buddy of mine's TM M4A1 RIS, the top RIS just fell right as he was holding onto the charging handle making the gun fall to the ground, conveniently hard concrete, causing it shatter into about 300 different pieces. Yay horror stories). The RIS allows the attachment of any normal 20mm scope mounts or rail accessory. As I said, this will lead us into the next portion of the gun's review: the RIS rail system, forward sight, and barrel assembly.

The RIS rail is an amazingly well built free-floating RIS system (which means it only connects at the receiver in order to reduce effects of human interference when holding onto the rifle). It is laser engraved with measurements and is your standard 20mm RIS system. It comes with 3 black rail covers which make holding the rifle much more comfortable when roughin' it through the terrain. I have been using and abusing this rifle (in the field only , I always take good care of her when I am home) for almost 6 months now and I have never detected a single flex or unnatural movement of the RIS. The gun also comes with an RIS bi-pod mount adapter allowing the easy installation of Harris bi-pods or anything of the like. The GR-25 also comes with a handy little flip up front sight which is made of all metal (like EVERY other piece of this gun ). The one piece outer barrel extends a few inches past the RIS with a gas block RIS holding it steady. Also, pre-attached to the barrel at the gas block is a QD silencer mount. Which leads us to the silencer itself. The Silencer is made of all metal with real foam inside to help dampen the sound. The silencer extends the length of the gun by about 12 inches and gives it an amazing tactical look. It has built-in quick detach module to attach it to the barrel in a snap (literally).

That about sums it up for the front end of the gun, and now to move onto the stock assembly.
The stock on the GR-25 is a standard M16 length stock allowing the storing of an ample size battery (9.6v3300mAh battery fits with easy). The wiring is very sturdy and contains a surge-protector right next to the contacts allowing for easy access or removal. The stock itself is the sturdies ABS plastic stock I have ever felt giving no warping, flexing, or twisting when shouldered and hauled around. The metal end is nicely textured in a similar fashion to the grip of the rifle and assists in rapid aiming (it makes sure it doesn't slip around on your shoulder), comfortable hold, and a good feeling when brought the bear in a rapid fire situation. The stock also has a sling ring for help in mounting a sling (although I would recommend a Special Forces sling which uses Velcro to attach to the rifle itself do to the sheer size of the rifle). The stock and grip are the only plastic parts of the entire gun externally. The gun is packaged very nicely in a foam protected box and comes with:
-Gun
-Silencer w/ QD Mount
-3 Black Rail Covers
-50 Round Standard Magazine
-Bi-pod RIS Adapter
-Loading Tool
-General Maintenance and Disassembly Manual

On the topic of disassembly, the GR-25 is one of the easiest rifle to disassemble, only requiring something to push the front pin out. It then locks in place, out of the way, allowing the user to slide the upper part of the receiver forward revealing the mechbox neatly tucked inside. This method allows INCREDIBLY access to the barrel, hop-up assembly, and charging handle. Now, lets move onto the parts that everyone really came here to read, how this behemoth of a rifle performs.
The GR-25 comes out-of-box firing at an awesome 380 feet per second. This give it an amazing potential as a DM or sniper weapon (especially for the fact that the durability of the internals are very high grade seeing as how I have had the gun for around 6 months and NEVER had to send it into the shop to get it repaired). The manufacturers at G&G are really determined to make this into an excellent gun and as a result of that determination, they send it with a tightbore barrel already installed and firing with incredibly good stock accuracy. After the proper modification to my scope and hop-up were performed I was able to hit a grapefruit sized target (about 8 inches in diameter, smaller than the size of a human head) at 125 feet with relative easy hitting it 9/10 times. But, some more detailed tests are in store: Accuracy at 50'and 100' (no where for me to test ranges farther than that without driving for... 3 hours).
In all of these tests I will fire 10 rounds at a standard sheet of printer paper and record the results. All shots were taken from a prone position with the assistance of a bipod. The BBs I used were KSC Perfect .25g.
50 Feet
-All shots hit
-4"x3" grouping

100 Feet
-All shots hit
-6"x8" grouping

One definitive thing I learned from this test is that I need new BB's
That is about all I have on the G&G GR-25 for now, so I'll finish up with a Pro and Con list and come pictures
Pros:
-Full metal
-Hefty
-Strong (no flexing anywhere)
-RIS for attaching accessories
-Comes with silencer and bipod mount
-Has G&G tightbore pre-installed
-Shoots 380 out of box
-Long gun allowing great accuracy
-Easy to maintain
-Full stock for the use of a large battery
Cons (not too many):
-Very pricing coming in at around $400-500
-Huge rifle to have to carry around, especially if things get unexpectedly tight
-Not compatible with M16 magazines
If you are looking for a semi-automatic sniper rifle or a DM weapon, this is an excellent choice since it allows the use of 90% of M16 parts and uses the same gearbox yet is unique enough to definitely drawn second looks from other players. This gun is easy to maintain and in the right hands is an excellent platform to work from. And now, just a few more pictures


Hope you enjoyed
