 6920 sling mount

I was just curious about a 6920 I ordered last week from DSG. It came with the front sling side mount attached to the barrel as usual, but the sling swivel is riveted to the the FSB in the 6 o'clock position like the Magpul version has, instead of the side mount in the 9 o'clock. It's marked JUN 12 on the bag and was wondering if anyone had seen them like this before. The rest of the rifle looks great, and it wasn't a big enough deal to refuse the transfer or anything like that. Just seems kinda odd.

Figured I'd add a few pics


With Rogers stock


With BCM gen II


Can't decide which stock I like better.

I like the BCM stock for the classic looks.

Mine also came with the Rogers stock and funny sling mount. I only had a few minutes to look it over before we put it back in the box (layaway) but I was hoping that sling mount switched over for lefty use or is at least removable.

There was a QD swivel in the pack. I actually have it plugged into the Rogers stock in the 2nd pic. I figure I'll just order a new rivet and move the swivel from the FSB to the barrel mount.

That's the way I feel too. Rogers was higher quality than I was expecting and comfy, but BCM just seems right.

The sling swivel should be riveted to the front sling side mount like my 6920 shown here (made in 2011), I also have another 6920 same as this made early this year with the Rogers SuperStoc

That's obviously a factory workmanship fault, you should contact the Colt factory customer service and give them your picture and request that they send you a correct front sling side mount with the sling swivel installed.

Also check if your bolt carrier gas key are staked properly and as well as your castle nut of the receiver extension.

Then perform a function check (see link below) with your selector on safe and fire (see semi selector position in the noted instruction).

You could remove the rivet at the 6 o'clock position of your FSB by using a small 1/16" punch on the concave side of the rivet, it will not remove the finish on the inside of the FSB rivet hole.

About your stock, I have both the M4 and SuperStoc, ask yourself what is more important to you the M4 classic look but the stock will have a slight movement on the buffer tube, or do you want a stock without movement and don't care about how it looks.

Thank you for your reply Alpha. I'll send the pic to Colt. Being that the rivet is $4 + about $6 shipping, they should be the ones to make it right. It passed function test and staking looks good. Good info on removing the current swivel, thank you. I'll put some round through it with the Rogers and decide. Gotta a lot of rounds on the BCM through the years and like it. Looks like a no lose situation

I bought a colt 6920 from DSG earlier this year, I still havent put the sling on. I guess I should look and see if mine is like your when I get home.

Just an update if anyone was curious. I e-mailed Colt right after my last post here with pictures of the problem and asked for any assistance they could offer. They never contacted me back. I figure calling them would be the only way to reach them. My work hours make it difficult to call during their service hours, so I just bit the bullet and ordered a rivet and clinched them with a ATS W404 brake rivet tool.



I'm pleased with the result. Actually looks nicer than the factory job in my opinion. I can put my OCD to rest and pick out a sling now

Glad that it worked out for you.
Good call on the buttstock too.

Looking at a Colt with a super stock is like watching a Thruroughbred Horse pull a plow.

Lol, thank you wes.
I do prefer the looks of the gen 2, but there's more to it than just looks. The overall length of the gen 2 is about 6 3/8". The overall length of the Rogers is about 7". On top of that, the gen 2 actually collapses further on the RE than the Rogers, making the LOP even shorter. Hard to tell from my pics, but the Rogers doesn't cover all the threads on the RE, fully collapsed, where the gen 2 comes about 1/16" from touching the castle nut. This has just been my long-winded way of saying that the LOP with the gen2 is about 3/4" shorter than the Rogers.
I like the Rogers and will keep it maybe for a future build. I'm just used to the gen2. I know some people like the Rogers and vice versa, I don't blame anyone either way. And the popularity with friction locks doesn't mean much to me. Once you pull the rifle into your shoulder, it's solid. Just my current opinion on the stocks, YMMV

Would you please provide some information on the tool you used for the rivet and where I can get one?

Thanks!

Sure. It's a tool in the aircraft industry used for relining brakes that use 1/8" semi tubular rivets. I'm not familiar with aircraft, but if you've ever worked on drum brakes, you might have seen the linings riveted to the shoes. It's the same size and style of rivet used on the sling swivel. The tool comes with a press to push the old rivet out, and a press to form the new rivet. The part that screws down goes into the hollow end of the rivet, while the bottom part of the tool acts like an anvil to hold the rivet head. It just barely cleared the swivel. I just put a drop of oil in the hollow end of the rivet to make a smooth, clean roll. It's really simple.

I got it HERE

And wouldn't you know they just put it on sale and offer free shipping right after I buy it Lol!
Hope that helps

Would that tool work to stake a receiver extension nut?

Unfortunately, no. The end plate receives the staking, and getting the tool around that would be quite a feat. I'm a tool freak. I always want the best tool for the job. I haven't found anything better than a center punch for a circular stake, or a ground screwdriver for a square stake job. It's really easy using either one of those.

I was playing with a 6920 at WM tonight.

Question on the Rogers stock, is yours tight, I mean REALLY tight? This one was a bear to pull out and push in. Yes, the friction lock was off.

I was thinking of buying the MOE 6920 but they sold it a couple of days ago and they still have 3 "standard" ones left. I may hold out for a couple of weeks to see if they get another MOE Colt in.

Hey Greg. The Rogers on mine moved easily on mine. Even with the lock off, there's very little movement. It still slid freely though. There's a slotted screw with a nylock nut that adjusts the clamping force on the lock, but if tightened too much it would engage the clamp all the time and act like you're describing. Maybe somebody messed with that screw. Tough call on whether to wait. I had my eye on this one for months and figured if I waited too long it would be gone, so I ordered it. It was sold out the next week. Who knows if the price will go up when back in stock. You always have the option of selling the original Colt parts and buying Magpul stuff eventually. Don't know how it is now, but in years past people were always looking for Colt double shielded handguards and side mounts. Maybe even the Colt marked Rogers Just an option to consider.

Ya, same with me. So another question.. Could something like this tool be used to push taper pins out of a gas block? The last taper pins I removed ended up needing a hydraulic press...

You know, it just might work for that if you were to use a socket on the fixed part of the tool. The curvature of the FSB makes it difficult to get a tool on there, but maybe with a socket??? I've had a ton of fun trying to remove those. The socket, a punch, and carpenter's hammer...yeah, sometimes. But I kinda got my kit together that's been working so far.



The black thing is a FSB cradle from ADCO. I prefer it to the orange R-Guns cradle, just because I don't like stuff that says "R-Guns"on it, lol.
Just oil the pins overnight, take 3 shots of Jack, and whack! Took my last BCM pins out without much force. It's all about supporting that FSB.

Yeah, I have this one and it usually works pretty well. Some of the Colt pins though are really f'n in there.

I're read mixed reviews on the Brownell's one. People say it's too squared off to hold the FSB steady. I never used it, so I don't know if that's their problem. What concerns me about the rivet tool is that I don't know how it would hold up to that kinda pressure. All it took to form the rivet I did was my thumb and index finger. Taper pins, as you know, are the biggest pain in the ass.

You have a link to those bench blocks that you're using? I'll pick them up and give 'em a try.

ETA: I'm a tool whore too.

Good food for thought. I would say someone did mess with the screw, that stock was way way tight.

I am holding off on buying one because I work at WalMart and when we worked on Thanksgiving we got a voucher for 10% off on top of our 10% off discount card! The only thing is that we can only use it on Dec. 6th & 7th only. So I am buying tires for the wifes car and a Colt at the same time as we get 20% off (1) transaction and not (1) item. She needs tires and I need want the Colt.

If I do buy the "standard" Colt I will leave her as is. I have others that I can play with.

I may just buy this one and keep her un-fired.

Is that possible?

I've got a 6920 that came with the Roger's stock.
Is there supose to be a QD swivel that come with it?

I ask because mine didn't have one in the accessory pack.

I got the black cradle from ADCO
FSB Cradle

I felt dumb paying that much for a piece of plastic, but luckily it worked when nothing else did. So my regret turned to relief.

The orange blocks I got from AIM but they're sold out now.
Bench Blocks

I haven't used these for taper pins yet, but they're pretty handy for general assembly. Don't know how they'll hold up to any real pounding.

Un-possible!! Haha! This is my KISS rifle too. I'm just gonna add a sling and get back to basics. It sounds like you're getting an amazing deal! Whichever one you decide on, I gotta feeling you're gonna love it!

Yep, there was one in my pack. Maybe you could give Colt a call and see if they'll send you one.

That's interesting. I wonder why they didnt mount the sling loop onto the side mount since it came with one? I noticed that on a newer Magpul type one I handled at a store very recently. I refer mounting the sling from the side because I always thought it allowed the weapon to be carried more flush to my body when slung over my back. I never understud how when they are making an M4 rendition and changing things like this. I never see the base model at my local shops with the regular M4 handguard and M4 buttstock, its always the magpul one or some version with a bunch of aftermarket stuff on it. Changes like moving the sling loop position make even less sense to me.
