 mounting a light without rails

Hey guys I'm going to ask a question that is probably a thursday question but what do you think is the best way to mount a light without having a set of railed handguards? This will be on a gun with mid length handguards and I think I would prefer a tape switch but I've never tried it in that configuration to know how well it works. Advice?

Lots of devices out there to circumvent a railed handguard setup. There are some that mount to the front sight post, such as one from Midwest Industries, and others that are bolted onto your exisiting plastic handguards, such as the rails from Streamlight. Still others mount onto the bayonet lug, and provide a railed surface such as the Cletus from Crosstac, or cheaper models from Mako or UTG.

I'm inclined to think that anything that mounts to the fsb wouldn't be all that helpful for accuracy and maybe a length of rail that attaches under the handguards would be best. I'd like to see if people running that setup agree or if it falls off, gets in the way, breaks when bumped against something, etc.

I've owned a MI FSB mount, and it held on fine, and can't affect accuracy, since it clamps to the sides of the FSB.

GG&G makes a rail which fits under your existing handguard, or you can buy First Samco plastic handguards which have rails built in.

And as far as your question about a tape switch, you really won't have room for one on a midlength after you get the rail and light mounted up. Most often tape switches are for use with a vertical fore grip.

Thats sort of what I was afraid of. I'm used to my surefire foreend with its tape switch on my shotgun and was hoping to sort of duplicate that setup.

Does the elzetta work on a light barrel with a .625 fsb? I thought I read somewhere it didnt but can't find that now.

Read the last two posts on this thread: www.ar15.com/forums/topic.html?b=3&f=20&t=354907

The Elzetta mounts should work on your lightweight barrel IFF you get a newer one. You may want to contact the company directly to make sure that you get a new one: www.Elzetta.com

You're awesome, thanks! So what do you guys say then about the practicality of something like elzetta which gets the flashlight forward and out of the way and a tape switch on the handguard? Maybe a little forward of the usual grip position to be sure you want to use it...

just the question I was going to ask.

I have Elzetta mounts on carbines, not midlengths, so I do not use tape switches (on carbines, the Elzetta mount puts the flashlight in a perfect location to just slide my hand forward into the sling swivel to operate the light and there is not much extra room on the handguard to mount a tape switch).

On a midlength setup, however, your idea sounds like a good one. With the longer handguards, you have many locations where you could mount a tape switch.

First off, what kind of light? I have my M5 mounted on with an $10 CTD item made by CAA. It has not gone through "riggerous military beatings" (but no gun here on ARFCOM has or will, so don't let them give you the "durable" BS!), but it has been bumped, knocked & abused with no problems... It mounts to either the CAR or M4 style furniture. Locking on tight enough that it is damn near part of the furniture itself.. Hell you could even weld (fuze the two pieces of plastic together) to make it one solid piece. It is the "poor mans Surefire 500 series"- LMAO!!

Ok, link no work... Go to www.cheaperthandirt.com & search for item #ARR-106

First off, as long as you don't get an excessively heavy light setup (M95x, M96x, etc.) to mount off the barrel or FSB there will be minimal affect on accuracy. You can go with a dual rail FSB mount, the Elzetta mount or a good barrel mount if you'll choose a 6v or 9v light setup that is in the 3-8oz. range.

Second, the CAA TRM-2 mount that is shown/linked above is a pretty good piece of gear and inexpensive but it may not sit flush on the mid-length handguards as the taper is a bit different than with std. carbine handguards.

Third, the Elzetta mount does work well on mid' & rifle length uppers in conjuction with a tapeswitch. You don't have to use a t.switch but it does keep you from having to change your normal hold.

I have a short rail under my AR that I mount a light onto. I have a 45 degree mount (leaning to the right of the gun) to which I attach the light. This puts the switch conveniently near my off-side fingers.

There are also mounts which clamp to the barrel, but I don't care for them. If I didn't have a rail to mount to, I'd at least consider the mount that attaches to the front sight system. Put it on the right side so you're less likely to be blinded.

Call me old fashion, I like things simple. Leaves me with plenty of handguard space for prone shooting when I have to qualify. I can hit the tape switch with my thumb when needed.

I have the MI FSB mount and a Surefire 6P in Weaver ring mount on my duty carbine. Works great, solid and in a great position. Haven't noticed an effect on accuracy.
