Questions & Answers
What is the length the .625 sight takes along the barrel?

Measuring from the handguard cap, the base which clamps around the barrel is about 1 13/16 inches (about 46mm). The sight itself curves up and forward from the base and takes up about 2 1/4 inches overall (about 57mm).

Does this front sight interfere with the Magpul MOE SL Handguard?

While Magpul says that the MOE SL is only usable with an A2 fixed front sight, they must be saying that for liability reasons. I have used the MOE SL handguard successfully with flip-up front sights from PRI, YHM and GG&G. Only the YHM required the end of the handguard to be filed (very slightly) for clearance. All three brands have worked FLAWLESSLY for me with the MOE SL.

Product Info for Precision Reflex PRI Flip Up Front Sights w/ .625 Crossbolt

The Precision Reflex PRi Flip-Up Front Sight with .625-inch Crossbolt stands out among other AR 15 Iron Sights. Precision Reflex makes AR 15 Parts with the front sight attached, allowing the front blades to go directly above the barrel where the gas block connects the barrel and gas tube. This gives the sight impressive stability and durability, which means it is much less likely to move or loosen after regular use. This Precision Reflex Front Sight weighs only 4.9 ounces, so it doesn't add too much weight to your weapon, letting you aim and fire for even longer without fatigue. Pick one up today to take your weapon to the next level!image
