The same can be said for iron sights, more length is always better. If a bipod is central for your build, they work best when mounted as far out as possible. Weapon mounted light, IR/visible laser, foregrip, and anything else you might want to attach. More length also gives you more room for stuff to hang off the rifle. Resting off of the barrel will cause POI shifts and it’s just awkward. Small and lightweight builds benefit from a shorter handguard, but having an exposed barrel at the end means it can be harder to shoot off barricades if you want.
You with a broken gas system, colorized, 2035, probably If the gas tube gets bent, broken, or cracked it can’t function.
It is also a critical part that could take a drop or hit. If you or anyone else touches it after shooting, it’s going to burn like crazy. If you have a rifle-length gas system but only a pistol-length handguard you’re exposing several inches of bare gas tube to the world. There aren’t a lot of parts on an AR-15 that require protection, but the gas tube is it. While technically not a limiting factor, I strongly recommend you consider your gas system length to be the minimum length of your handguard. Suppressors and linear comps are perfect for this but are really for niche builds. Faxon Ion Muzzle Brake, a safe distance from the handguard The exception to this rule is if you plan on running a muzzle device that extends past the end of your muzzle and does NOT have ports to redirect gasses to the side.
Secondly, there is a good chance it will damage or destroy your handguard. First off, it’s a safety hazard since you could get a blast of hot gases blown into your hand. If your handguard extends past your barrel you’re probably in for a bad time. How long your barrel is will, in most cases, give you a maximum length for your handguard. Drop-in handguards rely on the front sight block to attach to the rifle so you are limited to using the length that your FSB forces you to use.įree-floated handguards only attach at the receiver, allowing you to have an endpoint of your choosing. First off, we’re talking about free-floated handguards since these give you the freedom to choose your length.
