Things I liked: Not overly expensive, hold pretty many BBs, easy to reload and wind up.
Things I would have changed: Make it fit in the gun more snuggly.
What others should know: I got a gun that used this kind of clip. The clip fell out during a battle and I lost it forever. The clip design is great.  Anybody using the TSD SP5 will want to buy an extra one of these, since the low capacity mag that comes alongside the hi-cap is worthless, and without a hi-cap mag you might as well not even play.
Things I liked: It's decently accurate, and it just has a nice "feel" when you pull the trigger. It also has very high FPS for a cheapo stock-less shotty. I use it for mid-range shooting, but it works just as well in CQB. Sling-mounts are nice and sturdy, handle feels good, grip is good, and the heatshield just looks cool!
Things I would have changed: Bigger magazine! This gun loses a lot of charm because of the tiny mag, if it had a larger mag, or the option to buy a high cap mag like the Everblast guns, it would be perfect! Also, for some reason it's pretty heavy, even though there isn't a huge amount of metal on it.
What others should know: It can slamfire, but I don't recommend it. It's extremely powerful for a shotgun, it's pretty accurate, and if you have a speedloader handy the magazine size isn't a huge problem. For the price, I'd say this is the best shotgun available for CQB. Anybody who feels its sting at close range will think twice before tangling with you again!!!
