Be aware!!! - Leapers UTG Flip-up Tactical Front Sight MNT-751

PLEASE BE AWARE that the MNT-751 is intended for Gas Block rails and is .28" taller than a rail mount front sight. This is clear if you visit the Leapers website but (as of 11-4-13) was NOT mentioned on the Optics Planet product page. The correct UTG sight for co-witness with the standard height MNT-951 Tactical Rear Sight is the MNT-751L Low Profile Flip-up Front Sight. I ordered the MNT-751 and had to file a return. Fortunately, Optics Planet made the exchange process super easy, however, I still had to deal with the general hassle and waiting.
Pros: Heavy Duty construction
Cons: Not listed as Gas Block Height
