That's where free-float handguards come in.Ī: A free-float handguard quite literally "floats" over the barrel and gas block. The drawback is that such a handguard, when affixed directly to the gas block and barrel, can reduce accuracy. This handguard is considered the most "rugged." It would take an exceptional amount of force - likely enough to bend the barrel itself - to dislodge this handguard. These types of handguards typically have a quad Picatinny rail for attachments, or they'll be smooth, provided only as a place to grip with your non-firing hand, like the one below. As the name implies, a two-piece handguard comprises two halves, which meet together at the barrel nut and front sight bus / gas block, clamping together around the barrel and gas tube. Q: What is a drop-in or two-piece handguard?Ī: This is the original handguard design found on commercial AR-15s, adopted directly from service-issued M4s and M16s.
Is M-LOK better than KeyMod? Does a Picatinny rail still have its place on a modern AR-15? What's the difference between a drop-in handguard and a free-float unit? Let's clear it all up. With so many handguards available on the AR parts market, picking the right one can get a little confusing.
