Gun Name and maker: A&K SR-25 (Stoner Rifle-25) [Match]
Info about the real thing on wikipedia.org
FPS: 440
Hop up: Yes, adjustable
Mag Capacity: 450
Battery: Ni-MH 9,6 1100
Plastic/Metal/Both: Both.
Opinion and overall comments:
Not a sniper rifle exactly, more like a sharpshooting rifle (or para-sniper, if you prefer) because of the full-auto option.
NOTE: Be aware, the real gun operates only in semi-automatic mode.
OUTSIDE: First looks - well, I've seen better. But they cost much more. The gun's well built, the whole body being made of metal (ZnAl), just as the outer barrel, mech sights and RIS rails (and the silencer). The butt and grip are of course made of ABS, as well as RIS covers. Everything fits tight, but the gun is also easy to disassemble in the same time.
The silencer is a QD type, fully functional.
INSIDE: Chinese 'M140' spring SHOULD give the gun 440 FPS. New models measured on Guarder Speeder 2000 had 438 FPS (worst score) to 456 FPS (best score), with variations of +/- 5 FPS in one model. So - pretty stable. Tests made of 5 guns, each giving 20 shots, with Xtreme 0,20 BBs. Results (rounded to 1 FPS):
GUN 1: worst 442; best 448 = 445 +/- 3 FPS
GUN 2: worst 440; best 449 = 445 +/- 5 FPS
GUN 3: worst 438; best 446 = 442 +/- 4 FPS
GUN 4: worst 450; best 452 = 451 +/- 1 FPS (!)
GUN 5: worst 455; best 456 = STABLE 455,5 FPS (!!!) <= Hell yeah!
The gun holds a v 2 long GB, pretty standard, though real tough. More details lower. The spring guide is metal, with bearings. All bearings are made of steel, and the gears are improved and 'toughened'.
Overall rating: 9/10
Why 9, not 10?
1. It's not as pretty on the outside as the CA...
2. The mags are a problem - hard to get.
BUT THE STORY CONTINUES...
OPTION 1:
Forget the M140 spring. Get a M150. Effect? 412 FPS (+/- 2) on... 0,28 BBs
Or about 495 on 0,20 if you prefer. What's funny, adjusting the hop-up decreases that amount for no more than 5 FPS for the 0,28 (Xtreme) while highly improving the gun's range.
Get rid of the stock battery. Get a 2000 mAh 9,6 V, cover it with NRC to reduce power losses. It'll fit into the stock without any problems.
You can still shoot on auto. Effects in this configuration:
FPS: ca. 495-500
ROF: about 850 (!)
That's a sharpshooting rifle.
OPTION 2:
Forget the M140, M150 or even the M160. Get a M170. No, wait... hell yeah, let's ride a M180!
Forget the full-auto option. Cut it off, just to be sure no-one gets hurt. REALLY, DON'T USE IT.
Forget the 9,6 battery. Get a 11,1 LiPo.
Get a tough (i.e. Guarder) non-silicone bucking.
Chrono it. Go for a beer. Then chrono it again. Drink more beer. Sober. Chrono it again... believe it. Buy some 0,36...
Measured FPS on 0,20 Xtreme BBs with a GFC M180 spring and 11,1 Lipo: 620 FPS [+/- 7 FPS].
That's a sniper.
NO ADDITIONAL MODIFICATIONS NEEDED - the gearbox can take it!
[bTW - with OPTION 2 and a BSA Deer Hunter 3-9x50 scope, a matchbox goes down from a measured distance of 80 meters (ca. 265 ft.) - call that accuracy]
Good place to get your own...
