Question: Is it blowback
Document: I ordered the Walther CP99 blowback the next day because I read it feels pretty real (UPS is delivering it tomorrow, oh ya! ).
Who cares? Go buy a blowback gun and stop dissing this one.6) Too much plastic, too lightweight, etc. See #5.You want a useful negative comment? Here you are:  The CO2 door (the sliding handle) is too easy to come off and difficult to get back on.
ok first its a co2 Non Blowback. Which sucks. Now First Flaw is the structure. the Top came off after the second day. and the Co2 cartrige last 30 Minutes. IT HAS LEAKS ON EVERY ROUND. ITS NOT WORTH 46 BUCKS
So when i got the product, i put a new cartridge of Co2 in. i loaded the magazine with some bbs. so when i inserted it. i noticed after every shot the mag came out a little bit which i had to hold the magazine and push up on the bottom of it.Pros:Semi-auto19 round magazinebottom raildrop free magazineshoots as fast as you can pull the triggerMetal MagazineCons:LightweightPlasticNon-blowback actionsometimes jams
Pretty doggon' nice for the money, in my book.There is a guy on YouTube who does great reviews on replica airguns. I'm not going to plug his site directly, but if you can google, you can find it. In my opinion, he puts too much emphasis on moving parts, blowback, and other features which would make the guns more realistic, but he still does a very thorough review, and they are worth watching.Good luck.
Im not going to lie when i first got this gun i was a little disappointed but it was so lightweight and plasticy but after i loaded it and shot it i was relieved, i have to say if this gun lacked anything it would be metal and a blowback feature but besides that, this gun isnt too bad. if your looking for the best type of bb gun i would choose sig sauer, but i still have to tip my hat to smith and wesson.
This gun is POWERFUL. It shatters glass bottles from 40 feet, possibly further but I hadn't tried. This shoots STEEL pellets. Do not shoot this at people. You will unquestionably hurt them badly.That being said, on to some real specs.The gun is non-blowback. So all the co2 from each release is devoted to shooting the bb. More power. Also less moving parts.the gun is very well made. It's weight is average for a co2 gun.
The look and feel is surprisingly realistic. Some might want a blowback feature but, to me, that is just a waste of good co2.One thing to keep in mind. When I say it looks real, I mean it. If you are dumb enough to pull this on someone, you will wind up in jail or the morgue. Be warned.UPDATE JUNEAfter having had this gun for a couple of months, I'm even more surprised. As far as I can tell, it just does not leak.
)Features - 5.0 -  (witty placement of buttons, clip, safety switch, etc)Performance..Accuracy - 4.5 -  (simply above average)Blowback - 2.0 -  (almost non-existent)Sighting - 4.5 -  (cool neon-green coloring)I would note you can buy this at Academy for $39 and not worry about shipping (same with BB's and co2 cartridges) I was genuinely surprised with their selection! !
I was not sure whether or not to get this bb gun or a different one but I went with this one because its a replica of the M&P 40. For the price you cant beat it. Its got pretty good velocity and the  CO2 cartridges last for a while, first 2 magazines are really high velocity, 3-4 magazines are a little lower, and it drops off steadily. Can get several hundred shots per cartridge, much better than a blowback bb gun.
Answer: yes
