    "I have had this rifle for 3 years. Yes I've replaced parts, but such is the life of an air softer.

    I HIGHLY recommend the Co2 mags. I use them and this rifle is still serving me well. I've replaced the hop up rubber, inner barrel and some furniture. This rifle is absolutely amazing, and makes one heck of a gnarly sound when it shoots. During the local fields days of indoor, this rifle was the bane and fear of everyone's existence.

    Unfortunately the bolt carrier eventually wears out, and will need replaced. But it's been 3 years and I still haven't replaced it. The bolt on mine no longer stays open on the last round.

    Pros: Good weight
    Solid construction
    Awesome sound
    Reliable with Co2 mags

    Cons: Parts wear out the more you use it
    Parts are weird, so you have to substitute or special order sometimes(Evike now carries all parts for this replica).

    "Looks great
    Feels great
    Pretty much the way to go if you want to have a realistic operating and realistic look & feel

    That's about all I got out of it at least. First off, I barely used this. It broke in under 2 weeks (Less then 2000 shots fired.. still almost a full bag of bb's) after buying it, At most I would fire 200 rounds out of it (which was rare normally I only shot 2 mags in my backyard) every few days. No constant use for over 30 minutes basically and even after I lubed it, cleaned it every time and put it right back in the case and treated this gun like a god, the bolt has worn down after so little round that if I try to pull the charging handle back the bolt will not return and it will just get stuck. No, the bolt catch does not release it, in fact it doesn't even trigger it. After inspecting, it was quite obvious. The bottom of the bolt that is supposed to be smooth pretty much looks like you hit the bottom of it with a hammer a couple hundred times, it's completely worn away. I have heard negative reviews about WE products and I really wanted this to be a very good performing rifle (which for the price it should be) but if it stops working what good is it then? Not gonna lie, after saving for this I was super disappointed to see it break after such little use. Wouldn't recommend buying it obviously but it's your money so feel free.

    "this weapon system stock shoots about twice as far as my double eagle UMG with upgraded barrel and hop-up but is less accurate because I'm shooting at 150 to 200 feet.
    i use .3 gram BB's because i live and play in windy areas with tons of brush.
    evike has the LOWEST prices on the market
