Colt Bipod / Handguard

Posit · July 30, 2013, 03:50 PM

I have a Colt Mdl 6920 (M4 / Carbine); I want to be able to use a Harris bipod on occasion. I'm not an AR enthusiast, which will become immediately obvious; bought this one "just because", and for old time's sake.

I first thought a bipod adapter would be sufficient, so bought this one: http://www.midwayusa.com/product/404...-5-ar-15-black

However - the adapter requires a 5/8"wide by about 1 3/4" long (don't have it handy to measure) flat space inside the lower handguard to mount. The Colt handguard has a round heat shield inside the handguard, which prohibits mounting unless I modify it by cutting/bending - and I'm not certain that will work, and I don't want to do that anyway.

I'm thinking different handguards will be necessary, but have no idea what to get (remember, I'm not really an AR guy). Because my use is limited, I want to keep cost down to a minimal, but functional, solution. But, I must be able to mount the above dimensioned adapter inside the bottom handguard. Not looking to mount anything else, so rails are not essential.

I realize many people think a bipod is an unnecessary addition, detracting from the purpose, concept, etc, or the AR so don't need to know more about that. Also, I have several Harris bipods, so I'm really looking for a solution that will let me use them, not a different one.

While I don't believe they would work with the adaptor mentioned above, Magpul's MOE handguards are a relatively simple and cost effective yet highly adaptable handguard option.

You can find the carbine length handguards for around $30, and they are a simple drop in part that requires no fitting or special tools. You can also buy a number of accesories such as pics tinny rail sections, flashlight mounts, forward grips, and sling attachment points to help configure it the way you want. A short rail section mounted at the 6 o'clock position on the MOE handguard would allow you to mount most bipods.

FYI if the screw on that adapter will reach and can be tightened that adapter will work it's not a big deal if it flattens the metal a bit inside the hand guard if I remember correctly mine was like that also when I used that same adapter.

I'mnot adverse to buying different handrails - even drilling a hole so the adapter mounting screw will go thru- but I hesitate to buy without being able to see them, or knowing for certain they will work. Can't envision how a Harris bipod would mount on a rail?

It looks like, if I drilled a hole thru the heat shield, tightening the adapter mounting screw would distort the heat shield a lot before it was tight enough... might work - I just don't see how.

I used one a few years ago on an Armalite.. Worked very well. It should have instructions with it that tell how to secure it.
