I have an “old” Colt 6920 that is a 16” carbine from approximately 2013.   It was my first AR that really got me into the hobby.   I now have a bunch of other more “modern” rifles that have midlength gas systems, etc, that I enjoy shooting much more.

I really have no use for a 16” carbine anymore.   What would you guys recommend doing with it? Chopping it to 14.5? Selling it?

I live in a ban state, so no sbr option.

Thanks in advance.

If you have others that you like shooting more, then I guess sell it?  Doesn't seem you have any emotional attachment. There's usually a number of people looking for a Colt.

Keep it, there's nothing wrong with that setup at all, put it in the back of the safe

I don't know your state regs, but can you legally have a pin & weld?

If so I'd go for a 14.5" or 14.7" pin & weld with a suppressor host of some type.

Sell it and get a can/ mags/ammo/optic so you can enjoy the stuff you like shooting even more.

No sense in keeping something you don’t shoot when you have other stuff you do.

I had my 6920 upper chopped to 14.5 by ADCO. 16” with carbine gas just makes no sense and it also looks off, proportionally.

I had to sell mine during the government shut down to make my car payment so you can send it to me and I will put it to good use.

My 6920 from 2008 now hangs on my wall as my 20th century US Military "M4" example.  I know it's not select fire and has a 16" barrel instead of 14.5", but everything else is the same and it came off the same line as the contract M4s were at the time.  I say keep it.

keep it so you can give it to a friend when the zombies appear.

I also have an old 16" carbine.  Okay gun but it'll never get used.  isnt worth shit so it just sites in my safe.

Keep it.  

It’s gassed properly and I’d wager money that it shoots softer than all your midlengths.

Keep it (especially if you live in a ban state) and put it back into its original config if you changed it at all. Nostalgic reasons.

A .22 conversion FRT is the most fun AR to me. I’d do that with a HighViz front post. They can be a challenge to get running.

I agree. The 16” Colt carbine barrel is gassed really well and they are surprisingly accurate. Put a Geissele mk16 15” rail on it and a LPVO.

If it has a high shelf/web in the lower and an open C shaped carrier, it may be better to just sell it.  I SBR'd mine years ago, but would not do that today.  Mine also has a large pin trigger group, which is quite limiting.

2013 had a milspec M16 bolt group and lower with the web of aluminum intact in the area of the autosear pocket. The lower is also (in my opinion) the most desirable that Colt ever produced. Fully roll marked “M4 CARBINE”, 0.155” FCG pin holes, with no QR code. That rifle is a keeper.

I don’t know if you had it for what is now 16 years I would just keep it. You’ll regret selling your first ar. I had ARs that I paid 2-3k for that I sold that I never regretted once selling. But want to know what AR I regret selling the most? A 900 bucks Bushmaster Modular Carbine that was my first AR. In some ways I’m still looking for it but I doubt I’d ever find one again.

I wouldn't sell it right now. Market is horrible and psa had used colts for 699 today although they did sell out.  I'd wait for the elections or parting it out might fetch the most money. Colt parts are easy to move if priced just about right.

Having a spare plain old carbine is always nice to have and it's battle proven. Do you have another place you visit often like a GF or family members house you could stash a spare rifle at. Plenty of useful reasons to keep it.

Or trade fodder if you ever want to buy or have another gun you come across that the colt could knock a chunk off.

I wouldn’t sell it. Having a spare rifle is never an issue.

I picked up one of the “Carbine” when they lost the M4. Got an older one from AIM, trade in that was in just as good condition. Even better, it was an NJ agency gun… where I lived for quite some time. Sold the newer one to a newer officer.

Have multiple ARs, to include SBRs and all other setups. The Colt stays, being I know it is good to go. If I do a class, it’s my backup rifle. If, for whatever reason, I can’t bring an SBR… that’s in my truck locker. Doesn’t owe me anything.

Update it. I put a MI extended carbine MLOK FSB rail on my old 16" PD trade-in and breathed new life into it and gave myself lots more real-estate for accessories. There's nothing wrong with a 16" Colt. It's a solid foundation for a fighting rifle.

I just sold a 2013 colt m4.  It was my first carbine.  Not my first AR.  I needed to shrink my firearm size .  It was solid and never gave any issues.  I have  a Colt SoCom to pick up its duties.

This. My Carbine shoots much softer than my over gassed mid-length.

I put a 6920 with a 13.5” handguard on the same lower as a KAC SR15mod2 intermediate upper on the same lower and the 6920 was softer shooting with Carbine, H, and H2 buffers.
