I'm not trying to monopolize everyone's time. Just trying to line up my ducks with as much forethought as possible. If I wind up building my upper from discreet components, one item that represents a tough decision is the receiver. Obviously there is the conventional A3 flat-top and then there is the ever-growing popular lo-pro. The inherent strength in the 7075-T6 lo-pro is appealing, but I wonder about the loss of the Forward Assist. When I built the two 5.56 ARs I owned in the past, chambering was reliable enough that I never had to rely upon my FA to provide that extra umph to get a stubborn cartridge to seat. I know the 450 is a lot different physically than the 5.56 and wanted to hear from those of you with trigger time whether you find you need the FA from time to time? At the range, it's no big deal, but should I need a fast follow-up shot hunting, I assume that with the lo-pro, your only recourse is removing one of your two hands from the shooting position and cycling the charging handle to clear a problematic round as opposed to just thumbing the FA.What has been your personal experience with the 450B?
Thanks again,
Hoot
