"I bought this gun 2 years ago with amazing expectations. Before I was using a stock g&g combat machine on an 11.1 lipo and I was really just looking for a more reliable gun that I could upgrade later. Probably 6 months after buying the gun I began my extensive internal upgrades. I built an insanely fast gun that used a massive brick battery. From there I switched the internals to a new gearbox and new gun and threw a Polarstar jack and just recently put in a protech. I've now added an R-hop and a 6.03 tightbore. Although I only used this gun "stock" for 6 months or so but I was more than happy with it. The FPS and rare of fire were great with an 11.1. I never worried about anything breaking or anything of that sort. My only con with this gun is the 2 piece hop up. I really wish I could use a prowin or a retro arms hop up.

"This gun is amazing. I am kinda new to airsoft ( played for 2 years and plan on playing forever lol). This was my starter gun and at the time I didn't know much about airsoft guns and was kinda let down cuz I wanted an m249 but I took this gun anyway. Once I started to use it on the field and got to know more about airsoft guns internal wise I learned that an m249 is nothing compared to this sr7. Everything about this gun is perfect and worth it.


Amazing stock internals

I think it's made of steel

Pretty light weight for a steel gun

Comes with mag (kwa 120)

Too accurate to be true. Even with the fairly short inner barrel. I was able to be shot at multiple times then just turn around and shoot once and the other team would get mad cuz they thought I was cheating but the sr7 is just too accurate for CQB lol.


I couldn't buy 10 at once

The front sling mount makes a lot of noise but you can just tape it down and there will be no noise

2 piece hop up unit (this can be a pro or a con, personally I see this as a con cuz I can't put another hop up in it unless it's another kwa)

Doesn't come with battery or charger (most guns don't anyway)
