Thread: Ar15 Mags and Gas Block

What kind of gun did you get that has a fsb anyway?

Its a Rock River Arms - LA15 - ATH, well pretty much

16inch if I measured it right, - the hand guards match - just the FSB being odd

Like this - except for sight and maybe length - didn't get it from them though

know bugger all about them really - prob not my best decision, not the worst though ...

Was a good deal though

Like gimp, I've left my A2 sight on.
Doesn't worry me through the scope, as I'm used to it with my Vepr too.

Problem with the FSB is it can catch light and reflect it back into the scope, causing "white out". I have had this happen to me while stalking around clearings on a sunny day and it is a pain in the arse.
