no weight is given on the site, guessing it is aluminum though. personally I think it's not worth the $150, the "impact cap" I see no real need for since if this is all I got, I have bigger problem than smashing someone in the face with it.

the warp core, well, I can't reall tell how big the comparments are, but they look damn small in the photos. the (what I assume) tritium looks cool, but is rather pointless in something that is geared toward minimal weight.

could use some brighter color anodizing since if you drop it somewhere, it's mighty hard to find with the tactical black color. although i don't know if HA3 comes in anycolor other than black and natural gray.

all in all, I feel it's more geared toward the "commando" mentality. I liked the previous version a little better, this is a tactical version of it, not really an improvement as such.

having said that, if it's 1/3 of the price, you bet I'll be picking up a few, as it stands now, that money I can better spend elsewhere.
