Re: KAC- sr 15's worth the money ?
it's easy to explain, it just takes forever because there are so many features that distinguish it
lower features:
ambi selector
ambi bolt release
ambi mag release
(the latter two of which are slightly better imho than the POF/magpul versions)
built-in flush cups for slings
2-stage trigger
kinda cool, comfortable trigger guard, looks a little goofy though
the rest of the gun is equally cool though. i wouldn't get the lower by itself.
the bolt has rounded lugs and the extractor has two springs and inserts in the rear, and the extractor is wider so it engages more of the case rim
the quad rail has front BUIS built into the rail to save weight and space
etc, etc
