How to mount a Surefire M300A ?

Discussion in 'Black Rifle Forum' started by JerryinPA, Dec 8, 2011.

  1. I want to put a Surefire M300A on my AR.

    I do not have any rails on the forearm. I don't want to use a VFG. I want to leave the light off most of the time, but be able to attach it quickly. I'll just use the tailswitch... not a tape switch.

    Would I be better off to use one of the railed sections that attaches to my forearm, one of the railed sections that bolts through the front sight base, or one of the railed sections that bolts onto the bayonet lug?

    Or, am I missing an option?

    Thanks,

    Jerry.

    What kind of handguards are you using? That makes a big difference. If you have MOE handguards already, then the MOE illumination kit, or a IWC mount would work nicely.

    Edit: I would not suggest mounting a 300 scout with a bayonet lug adapter, as it will put the light in a really bad position - both for activation, and the shadow cast by the barrel will be at 12 o'clock. Ideally, that shadow is either non-existent, or is cast in a direction out of your main cone of vision.

  3. I just have the basic, basic handguards... not MOE.

    OK, I can see where the bayonet lug adapter would cast a nasty barrel shadow... I hadn't thought of that.

    Thanks,

    Jerry.

    Unless you have something against them, I'd suggest investing in MOE handguards, and either the MOE illumination kit, or an IWC cantilever mount to get your light up and running. You won't be looking at a significant investment (especially compared the cost of a M300), and the MOE handguards will give you a lot of options later on for upgrades.

    Edit: Learn something new every day. IWC is making a mount similar to the one I linked already, but it fits standard M4 type handguards. It will still get your light in the right position, but won't require a handguard change.

    What Plank said.

    I'd use a MOE, piece of rail and a LaRue mount but the IWC isn't bad.

    I used to have one of these, it's a great mount for someone in your position.

    IDK about the SF 300 situation though.

    Edit: it does come with inserts to allow you to fit lights with different size bodies.

    Nope. The body of the light has a protruding, flat section that the standard rail mount screws to. I doubt very many ring-type mounts would fit.

    If I was running standard handguards on my LE6920 I'd go with IWC and have suggested the mount to several friends/beat partners who are running standard handguards because they don't want to pay out on a rail system.

    If you decide to run a rail in the future, go with Gear Sector or Haley's new mount (which will be replacing my GS mount soon).

    I run a Gear Sector for my M300A on my DD rail. It rocks.....
