Colt 6720 upgrade suggestions

[MacFord125]

I've got a Colt 6720 inbound, should be in my hands Tuesday or Wednesday. I want to do a few upgrades/modifications and I could use some help with that. I want to keep this rifle as light as possible, but need it to fit my requirements. It's purpose will be home defense, general range shooting out to 300 yards, and a woods type walk-about gun.

A new stock is an easy one: the BCM Gunfighter stock. I have these on 3 BCM rifles and it fits my needs. In the meantime, I have a spare Aimpoint Patrol that I will put on it. The Patrol is a bit heaver and bulkier than I want for this rifle. So at some point I will replace it with an Aimpoint H-2 in a Bobro mount.

Now here is where I could use a little help. I want to replace the handguards but not sure what to get. To keep costs down I would prefer to get drop-in handguards. I am not married to any type of handguard, i.e. M-LOK, KMR, etc.. My other rifles are a mixture of handguard designs and have not settled on what I like best. Due to my age and a long ago injury to my left wrist, the use of a vertical grip works best for me. The thumbs over/c-clamp method just does not work for me. I usually run a light at 11:00, activating it with my off hand thumb.

With the above said, what handguard would you suggest?

[MistWolf]

I have no experience running a vertical foregrip other than to know I find them uncomfortable. That said, of the drop in handguards I've tried, triangular, round, MagPul MOE and MagPul Slimline, my favorite is the Slimline first and the MOE second. I don't know how difficult it is to install a VFG on either because if I wanted to, I'd figure out a way to do it. I will point out that the Slimline uses M-Lok slots and I believe there is a VFG that's made to for the M-Lok. Why I'd suggest the Slimline is because it's longer than all the other drop-ins, has a slender profile, protects the hand from barrel heat, fits the rifle tightly to eliminate most if not all rattling and is affordable.

I run an H1 Micro and I think it's a great sight. I think an AR should also have a sling. The Vickers padded Blue Force sling is a good one and weighs about a half pound. I run a weapon light on the FSB at the 12 o'clock position, but with your injury, that probably wouldn't work unless you were to set it up with a remote switch

Midwest industries has drop in hand guards for key mod, M-lock and 1913.

I had the Midwest Industries Gen2 G2 Drop-in (http://www.midwestindustriesinc.com/index.cfm?fuseaction=category.display&category_ID=64) on my Colt 6920 up until I switched it out for a free-float rail.
It was by far the best way to add an AFG or stubby along with lights and switches.

[henschman]

The easiest/cheapest way would be a Magpul MOE slimline and their Mlok VFG that attaches to it. For a light, I'd probably mount one to the front sight base.

Great choice with the 6720.

BCM Gunfighter Grip.
The grip is not the sexist thing to upgrade, but it's the thing you're touching virtually 100% of the time.
I hate the A2/whatever grip with a passion.

[ace4059]

Op,
Don't forget the sling and a QD mount setup. I prefer the HK hook because in the field the push button QD has come loose dropping the rifle.

I also prefer an ambidextrous 45° safety lever. Place the gun on fire with my thumb and on safe with my trigger finger.

Hand grip, rail, and vertical grip is all user preferences.

Sounds like you are set on the optic. Just setup your WML and you will be good to go.
What more can you ask for?

Thanks for the reminder, I have a spare BCM Gunfighter grip that I had forgotten about.

What rear sight is that? Thanks

Basically a DD style rear sight with a QD lever

I suppose I'll be that guy...

Why not shoot the piss out of it first and then decide what you actually want to change?

Thank you for your thoughts. I have been looking at the Vickers padded Blue Force Sling, but will now go ahead and order one. And I too really like the Aimpoint Micros. I currently have a T1 and T2, and really, really like them. I just ordered a Steiner 1-4 for another rifle so I will need to postpone the H2 until next month. Heh, and I thought the 1911 was addictive.

I understand where you are coming from, and good advice too. Normally I do not make any modifications until I give a new gun a good workout. But I have some other AR's, and due to my wrist problems I have already discovered that the use of a vertical grip is the best way for me to hold/control the AR type weapon. The Gunfighter stock was easy because I already have 3 of them in use, just like how they feel. But for some reason the handguard was throwing me for a loop.

Thanks for the info and link. This might be just the ticket for another rifle that I'm playing with.

I'm not quite sold on the QD sling setup either. I will definitely checkout the HK hook. I have an ambidextrous safety on my SR 15 Mod2 (because it came with it), but have not yet tried one on my other rifles. Is there a particular brand that you would recommend?

[ace4059]

I love the BAD ASS 45° safety selector with a short and long lever. Short on trigger finger side long on thumb side.
I've also have the noveske/magpul on one rifle but it just feels cheap.
Out of all the slings I prefer the padded blue force VTAC. I've tried several and I switched them all to the VTAC.

I know I made links to other threads here Ambi safety (https://www.m4carbine.net/showthread.php?179077-Ambi-safety&highlight=threads)

As far a handguard goes: MOE SL Hand Guard (https://www.magpul.com/products/moe-sl-hand-guard-carbine-length)

For other suggestion, I want three things on my carbines:
1. Optics (sounds like you go that covered)
2. Sling (Can't recommend the VCAS enough, I'd go with a QD version. Your BCM stock is all ready set up for it just get a QD socket for the MOE SL handguard either from Magpul (https://www.magpul.com/products/m-lok-qd-sling-mount) or what I like is the flush mount from IWC (http://www.impactweaponscomponents.com/product/qd-micro-mount/))
3. A powerful light (some type of Surefire, I like the X300 at 12 o'clock on a Mossie Midnight rail (https://www.m4carbine.net/showthread.php?174277-Need-extended-rail-options-for-a-6920&p=2186543#post2186543), but there are a ton of other option including a 1" mounts for handhelds or mounts for Scout Lights from IWC (http://www.impactweaponscomponents.com/category/mount-n-slot/light-mount/), check out this thread for options: Light mount help on my sbr (https://www.m4carbine.net/showthread.php?179787-Light-mount-help-on-my-sbr), Arson Machine (https://www.arsonmachine.com/) and Arisaka Defense (http://arisakadefense.com/))

[MistWolf]

I really like the Mossie Mount & Surefire light. I modified mine along with the FSB to get it to sit a bit closer to the barrel

Here's a shot of my shorty (I call it the Wolf Pup) with the Slimline handguard

Place the gun on fire with my thumb and on safe with my trigger finger? Is this common?

[ace4059]

Probably not. As soon as my finger comes off the trigger and I bring it out of the trigger well, the first joint on my finger (where the index finger connects to your hand) pushes it on safe. It's just becomes a habit and a quick and fluid motion.
As soon as I have the target in my site and as my finger goes in the trigger well my thumb disengages the safety. It's quicker than the traditional safety.

It only works smoothly with the 45 degree safety. The 90 degree safety rubs a blister on the side of my index finger joint.

[TMS951]

I recently went through this.

Difference was I had some spare parts around. Big one being a Daniel Defense RIS II, and Geissele G2S trigger. Those and a B5 SOPMOD stock made an awesome little rifle.


Now if I had to buy parts I'd buy a Troy Industries 13" M-Lo rail. They are 200$ or less depending on seller price.

This rail can be installed one of two ways. One is totally take it apart, to include the barrel nut, this will allow you to easily remove the delta ring and hand guard cap, and grind down the gas block off the barrel.

Now you can also grind the gas block and cut/removes the delta ring and hand guard cap assembled. IDK if one way is easier than the other, the later probably requires less real tools, but more of the bubba gunsmith mentality.


Either way good buy, imo the 6720 is the best value on the market.

This.

And after said piss is shot out of it, I think you would find value in any of BCMs offerings of charging handles.

[WillBrink]

I'm not sure how many rnds constitutes "the piss" but I did find shooting my 6940 stock for a year or so a valuable approach coming from a clunky BM that had a bunch of junk on it (in my defense it was all given to me) and unwise to the ways of the AR. Time spent on M4C is what really helped straighten my major malfunctions. I wanted to at least put a decent RDS on it, but held off, and when I did add the RDS, it was that much better in terms impact on my shooting it and appreciation for what an RDS can do. The BCM GF charge handle seems one of the best values out there in terms of $ spent to benefits had from my minimal AR experience and minimalist approach

Can't change the rails on the 6940, but for my needs, that's fine.

Pretty much what I've done with my 6920. The only thing I did right away was add an Aimpoint Patrol as iron sights and I just don't get along much anymore. I used the 6920 to "reintroduce" myself to the AR design. Shot it a bunch and then started adding more rifles and trying out different sight/scope combinations, stocks, handguards, etc..

That's what I do.
