bushmaster
i bought a bushmaster 97s when they came out. i sold it yesterday because the gun is hard to hold onto. if you want to put a forward grip on it you have to register it with atf. i didn't want to wait 6 months for the paperwork to come back. when i shot it it was really loud and had a 1-2 foot flame that came out the barrell. it was a real attention getter at the range. i put a single point sling on the back and used it to steady the gun when i pushed it out. i sold it and bought something more practical. still it was pretty cool.
also the bushmaster i had did not like wolf 55 gr ammo. the case got stuck in the chamber a few times. my bushmaster m-4 loves it though.
good luck
