Daniel Defense 15049067: The Daniel Defense M4 V7 SLW is one of the lightest, fastest-handling rifles available in the DDM4 line-up, tipping the scales at under 6 lbs. Built around a Cold Hammer Forged, 14.5\" Lightweight profile barrel, the V7 SLW has an Extended Flash Suppressor which is pinned and welded to reach the NFA required 16 minimum barrel length. A free-floating MFR 13.5 handguard offers incredible weight savings as well as superior cooling, ergonomics, and modularity while maintaining the strength and durability expected from Daniel Defense. With the M-LOK attachment points that run along 7 positions and an uninterrupted 1913 Picatinny rail on top, the V7 SLW has plenty of room for the sights, optics, and accessories the operator may require.
