View Full Version : Install USGI M16A1 Buttstock on Colt 6920

I have the Colt LE6920 with the Rogers adjustable stock. I am wanting to install a Buttstock from here:

http://www.uscoreplicas.net/

Just click on "Early M16 Handguards, buttstocks, etc." over on the left and it will take you directly to the page with the stocks on them. The ones I am intereted are the two at the very top. This place is somewhat local to me.

This is my first AR style firearm and am more familiar with AK's. Haven't even fired my 6920 yet, but have disassembled and reassembled as much of it as possible a couple times just to clean & lube it. Much different than the AK's.

My question would be: What do I need to order to install the M16A1 stock? Will it mate up with my rifle? I assume I will need a different buffer tube, but can I use my existing spring, buffer and nut, etc?

I went to WM to buy some windshield wipers and left with the 6920. They had four to choose from. I got the one that had the best finish and least play between the upper & lower. I checked a bunch of them out and the slight amount of play does seem normal. The only other comment I can make is the handguard does rotate slightly along with the delta ring around the barrel. The delta ring is tight but I think the cause of the play is the hole around the gas tube. The rifle is staked properly.

Thanks,

Jon

A standard A2 tube, buffer and spring should work. I believe the only thing you will need is the shorter stock screw that the A1's use.

Unless you plan to do this often, you might be better off finding somebody locally that has the tools already to help you do it. Buying an AR15 Armorers tool, a lower vice block, bench vise and assorted drivers, might not be cost effective for just one job.

But anyway, you would need:

Just want to add that the Magpul fixed MOE stock is out and it is in between A1 and A2 lengths.

I have the vice and other small assorted screwdrivers, etc. The stock I am looking at is $29-$39.00, at that price it gives me some wiggle room with the tools. I notice the price of the lower vice block is all over the place, anywhere from 10-60 dollars. About the same with the wrench, I notice Rock River has one for 6 bucks. I don't mind paying for a quality tool, but I don't mind paying less for a lesser quality tool that won't be used very often.

I will say this, if I really do like this Colt, I may attemp to build another rifle in the future but my guess would be that it would be already partially assembled; I would like the ability to put the stock on at the minimum. I do like retro stuff.

Can you give me an idea on which lower vice block and wrench would work for my needs?

Thanks,
Jon

I have the vise block set from Model 1 Sales, DPMS Armorers Wrench and a Craftsman torque wrench. I do a lot of Armorers work on my AR's though. May be overkill for one or two jobs, but having the right tools to do it the right way is worth the price.

Sharp looing 20" build you have there. Very nice job.

I agree, find someone with tools and experience to do this if you're not familiar with the rifle.

I have to ask...why do you want the change? The Rogers stock is very nice and locks up very solid. I don't see much difference between it locked and a fixed stock.

Why the fixed stock??

I like that old school look, I guess!! I do understand how to change the stocks and understand the rifle buffers and carbine buffers, etc. But for now I have changed my mind as the Rogers/Colt stock will do...it is lightweight which is one of my goals. I notice removing the sling mount beneath the front sight base and the carry handle while adding a flip up rear sight knocks a little over a half pound off the rifle.

Thanks for all the help.
