Re: Scope Height AR-10T

The tricky part about scoping the AR platform is the straight comb height of the stocks relationship to the reciever, I just don't know what height rings would give me the lowest comfortable cheek weld. </div></div>
I have scoped plenty of ARs in my time...trust me when I tell you that you want the scope as low as you can get it on an AR-10 with the bell clearing the handguard (or top rail of the handguard).
Your scope has an approx. OD at the bell of 2.4" (61mm) if you assume you'll be running lens covers (you can assume a little small without them). SO...
[(61mm OD - 30mm Scope Tube)]/2= 15.5mm OR 0.6102"
The minimum ring height, base to bottom of the ring, is 0.61". Or...depending on the mfg of the rings, you'll need 1.201" rings from the base to the center of the ring.
Those measurements also assume that you are running a railed handguard. If you are running the newer, aluminum AR-10T FF handguard, you can actually go a hair lower than that because the top of the HG is lower than the top of the receiver rail.
