anyone have a chronograph I could use/borrow/buy? would like to meet up at elk neck or freestate sometime to see how fast my 77 and 75gr loads are moving.
I have a few questions about moving to md with an ar15:
I have owned my ar for 5 years is it grandfathered in?
It does not have collapsable buttstock does that matter?
It has permanently pinned flash hider
are both uppers allowed? 556/300blk
magazines? i have many 20-30rd mags
any...
