I got the loader on sale at PBL for about 40 bucks off. I was glad to get it, since my Halo B was breaking up.
So i have not used it much yet, but i have been test firing it and all that and found it to out do the Halo B easy.
The pulse mode is awesome, easy on brittle paint.
Only down side i have been having it is rocks in the feed neck when tight. Seems like it not getting a great fit.
I shall update my review soon with more details.
it rocks like forward and back or side to side or something else? I find that hard to believe because i can barely get mine out of the feedneck on my VS-2. Dont get me started on how hard it is to put in.
