"It's a great sniper for what you pay for! I'm a beginner at airsoft sniping and this does the job. With .28's it goes around 150 feet with the right hopup. Taking it to the field soon and gonna see how it goes with other people.

"If you're looking for a bad, unreliable, inaccurate, cheap, fragile, piece of garbage, you've come to the WRONG gun. This Rifle is great for starters looking to snipe, most airsoft snipers require upgrades and mods for them to out perform AEGs, but with this I can out shoot my friends G&G Combat Raider with ease. It aint no Novritsch SSG24 but god damn will it try to be.

-Light (If inner weights are removed)
-Adjustable rear plate and cheek riser

-lacks threads (not big deal)
-Sling mounts are on left side

"Great beginners sniper and very upgrade friendly. Its weight can be reduced by removing 3 metal cylinders, 2 in the stock and one near the mag well once the gun is opened. Overall it's a great rifle and I would highly recommend this to anyone who wants to start airsoft sniping, it can easily reach 100ft with .32s.
