The Lo-Pro Slope Nose Free Float Quad Rail from Phase 5 gives your AR-15 a radical, futuristic look - but the looks are its least unique feature. The Lo-Pro is all about maximizing accessory mounting real estate, while minimizing weight and bulk. Hence, the front end that extends the top Picatinny rail well forward but slopes backward to the underside of the handguard to keep the "Slope Nose" as trim and maneuverable as possible. The Lo-Pro Slope Nose handguard comes in a Picatinny configuration with a full-length top Picatinny rail, plus partial Picatinny rail segments up front at the 3, 6 and 9 o'clock positions. The M-LOKA(R) model has short Picatinny rail segments Mfg: Phase 5 Tactical
