Let's take a quick look at the 3 AM/XL dart clip (mag).
Like with the UT blasters, the clip (mag) release is a cylindrical button behind the magwell that is pushed up to release.
For me the slide is quite comfortable to grip. It's sufficiently long and tall, and quite wide making for a good amount of grip area.
Ranges are reasonable, about 11m flat extremely consistently using the flat tipped AM darts. Switch to Nerf's Megas gives a significant range improvement, comparable to a Magnus, though consistency goes out the window, since some will drop short and some will soar really far.
Accuracy is pretty impressive, the flat tipped AM darts fly extremely straight. Even with bouncing I was having all the darts I fired land within a circle about 0.5m wide.
Rate of fire is decent, though not fantastic. The AM3/Boss is quite easy to prime, but without slam-fire and with such a long priming stroke it certainly won't be winning any ROF contests. About 2 darts per second is about what I can get.
The Air Max 3 is not currently widely available in Australia yet, but is available at Mr Toys Toyworld for 25AUD (for the purpose of rating I will be ignoring that price, as it's an independent smaller retailer). The RRP in the US is 10USD, which is absolute bargain, considering that's about the same as a Strongarm. Nerf's competitor, the Magnus, retails for about 15USD (though naturally on sale it'll drop down). While twice the price compared to the smaller Air Max/Baron, the AM3/Boss performs similarly well, is much more comfortable overall and as a general use blaster is much more practical due to its clip (mag) system.
If you're at all into the Mega line, the AM3/Boss is highly recommended. It's a cheap, effective and reliable clip (mag) system Mega blaster, something Nerf has failed thus far to do.
If you're purely into practical use, then the AM3/Boss is possibly a decent sidearm, though I'd personally only use it for such if Megas are treated specially (e.g. instant-eliminate a double-tap zombie) as for sidearm duty I personally would prefer the one-handability, greater capacity and smaller size of the Sweet Revenge. While the clip (mag) allows for easy reloading provided you have more preloaded clips (mags), reloading on the run is not as easy and so for scavenging/reloading on the run the Magnus is superior.
For just having fun, the AM3/Boss is a pretty good choice. It's very cheap, performs well and is really fun to use. An advantage it has over regular blasters like the Strongarm is that it fires Mega sized darts, which add a novelty factor not present with regular dart blasters. If you get yours from North America you also get the suction tipped XL dart, and sticking suction darts to flat surfaces is always fun.
I'd certainly recommend picking it up if you have a little spare cash and space.
Pros: compact mega clip (mag) system blaster, very cheap, performs quite well
Cons: poor for scavenging/reloading on the move without spare clips (mags), included clip (mag) is very low capacity
Rate of Fire: 3/5
Value for Money: 5/5
Personal Rating: 4.5/5 - it performs pretty well and feels awesome to use. I also find it quite comfortable (besides the trigger finger issue), and the low price of 10USD doesn't hurt either.
Again thanks to Buzz Bee for sending the Air Max 3 for review, it's another great blaster.
