Perfect - rugged, reliable, strong - Leapers AR-15 Deluxe Riser Mount with Picatinny and STANAG Dimension -Not See-thru MNT-A95

Got this for my AR-15. I put a fairly heavy scope on top of it, sighted it in, then checked my rifle and scope (still on the rail) on an American Airlines Flight that stopped in Dallas, TX.

TSA, in their amazing stupidity, searched my bag and moved the scope from the protected insides of clothes to the very outside, where it took the brunt of the forces of being dropped and thrown around by the baggage people.

Upon getting home, I went out shooting, reattached the scope rise, and shot a 1" shot group at 200 yards with cheap .223 ammunition without really trying.

This left no doubt in my mind that this is very durable and reliable - especially since it has the long attachment rail that helps put it on the rifle in the exact same orientation every time without effort.
