Plus, turns it into a tubular handguard like JP ones, comfortable to handle. I liked a lot that the upper rail can be detached. Allowing us to place only a small section for a flashlight or an An/Peq to reduce weight even more. They’re not designed to be quick-attachment. This handguard arrives with 4 picatinny rails already installed, fixed by Torz screws to metal plates on the inside of the handguard. It features mounting points a 2, 3, 6, 9, 10 and 12 o’clock orientations. First thing we noticed is the lightness, weighting only 288 grams. We move on to the carbon fiber rail, which is truly manufactured on said material, not an imitation water transfer. It’s like they doesn’t have the proper size, or maybe because they’re flexible. I also ordered some AABB textured panels to improve the grip, but I’m not able to properly install them. I’ve chosen a Big Dragon QD sling attachment replica of Knight’s Armament because handguard lacks one. The latter being most common one to take advantage of all accessories we already have.

Speaking of KeyMod accesories, everything on the military world that is expensive delicate will be placed on the upper rail (An/Peq, NVG or thermal scopes) and the accessories using KeyMod system will be cheaper ones like vertical grips, rail sections or flashlight mounts. The slimier profile feels comfortable while grabbing the rifle. This is the KeyMod handguard on a WE M4 CQBr. While I was installing it, I though it lacks something that keeps it on place (other than the gas block and tube) instead of only relying on how strong we tighten it. Barrel nut has multiple screw holes so we can tighten it and still be able to align the handguard with the upper receiver without trouble. The the handguard is attached to the barrel nut by 6 Allen screws. It isn’t essential but provides more stability. Now we’ll install the gas tube and gas block. Like I said in the beginning it’s a firearm accessory and therefore barrel nut can only be installed on brands with real steel threading like WE, Systema, Celcius, maybe Inokatsu and Western Arms. It would be nice that all Vector Optics rails included some washers as the 12 inch model does. First insert the barrel nut and fully tighten it. Low-cost option will be to knot some paracord. Vector Optics chose not to include any attachment for QD sling swivels, nor the keyholes admit them. Handguard is made of mechanized aluminum and its finish seems to be paint instead of anodizing. While picatinny sections can be attached, they’re so close to the upper rail there’s no room for mounting anything on the section. Because of that picatinny top rail on the 2 o’clock and 11 o’clock positions we’ll only be able to mount KeyMod accessories.
WHICH WAY TO INSTALL KEYMOD ACCESSORIES FULL
Vector Optics KeyMod handguard has an octagonal shape, featuring a full picatinny top rail and KeyMod holes on the remaining 7 faces. Then we just fully tighten the allen to lock it in position. Tighten enough so the indent doesn’t rotate freely, but loosen enough that we can insert the accessory into the keyholes and slide forward. How does KeyMod system work?Īll KeyMod accessories include at least one attachment which can only be mounted one way only, with indent facing forward.

Vector Optics specifies a 395 grams weight for this 10″ length. It’s goal is to reduce handguard weight and profile by eliminating all picatinny (except the top rail) and placing rail sections only where we need them. It’s one of the two main modular standards (the other one being M-Lock) and named after the keyhole shaped attachment points. The KeyMod system is a public domain patent designed by VLTOR as a replacement for the picatinny standard. Vector Optics Slim Keymod rail What’s the KeyMod system? KeyMod handguard comes with two small and detached picatinny sections, and we’ll start our review with this one. Carbon fiber harndguard is very lightweight (obviously way more than the KeyMod) even with all rail sections attached. As it was said multiple times, Vector Optics is a Chinese manufacturer with a good quality because their products are designed to be used on real firearms.īoth handguards arrive inside a cardboard box, wrapped on plastic bags and with all required tools to mount them (Allen or Torx wrenches). Previously I reviewed the Vector Optics Mustang shortdot scope(spanish), and on this occasion the items will be two handguards. On this new review we’ll see two of the handguard models Vector Optics offers for M4 type rifles: KeyMod and carbon fiber.
