Here is a little Tactical Handyman project for your weekend courtesy of Echo Nine Three. If you have a spare AR-15 receiver end plate laying around (who doesn’t?), you can turn it into a sling adaptor. Gentlemen, start your Dremels!
Don’t forget to stake everything in place when you are done!
When I showed the prototypes of the V4-QD sling mount from Echo Nine Three, several of the under folder AK owners out there blew up my inbox asking when it would be available. I have good news… It’s available!
I haven’t put hands on one of these yet but I wouldn’t be surprised if it turns out to the best rear sling mount available for AKs with under folding stocks. It gives the shooter a centrally placed QD sling swivel socket in a stationary location that should stay out of the way of the stock fairly well.
Check out the V4-QD on Echo93.com.
If you own an AK with an underfolding stock, get a box of tissues because tears of joy are about to flow down your face and I don’t think I am overstating this (maybe a little). Underfolder stocked AKs are notoriously hard to sling. Well, that is about to change when the Echo Nine Three V4/QD Sling plates are released.
The picture shown above is a prototype mounted on an AK with an underfolder. We have talked about the V4/QD before but only in the context of use on AK pistols. Now that I have seen this, I think these are going to jump the head of a very short line of sling mounting options for underfolders. It positions the sling at the rear of the receiver where it can be used for single and two point sling applications and is tucked nicely out of the way. It uses standard push button QD swivels and is fully ambidextrous.
Installation is just as simple as the other Echo Nine Three Sling Plates. Just remove your grip, drop on the Sling Plate, and re-install the grip.
That sound that you hear is the joyful exclamations of AK underfolder shooters everywhere. These should be available in the next few weeks. Check out Echo93.com.
Echo Nine Three (E93) has a couple of new items in the works. The first should make Yugo M92 PAP AK Pistol enthusiasts pretty happy. The V4/YP/QD Sling Plate is going into production and should be available soon. It is a new version of the V4/YP which is compatible with QD sling swivels.
E93 is also working on a new sling. It is sewn from 2″ seat belt webbing so is is comfortable and bears weight well. Each end has an ITW Clash Hook (HK style snap hook) sewn in and there may be a QD variant eventually. This sling is designed to be extremely simple. It doesn’t have a name yet but you can suggest one on the E93 Facebook Page.

I’ll start this review with a bit of a history lesson. Joe Elledge of EchoNineThree (E93) was one of the few factory trained armorers qualified to work on the CAV-15 MKII lower receivers back in the days when they were still being made by Cavalry Arms. Apart from his standard armorer work on the lowers, he developed a set of modifications for the lowers that dealt with some of the perceived shortcomings and adapted it to more modern techniques.
Before you say anything… yes, I know the front sight is backwards. It works better as a thumb stop this way.
The modifications included shortening the buttstock, stippling the grip, and undercutting the trigger guard as well as adding a sling mount of his own design. The modifications were so well executed and well-liked by Cavalry Arms that they allowed the mods to be completed under warranty! Many of these features were to be included on the MKIII version of the CAV-15. However, setting up production of new receivers is expensive and the well-publicized drama between Cavalry Arms and the BATFE took place before the MKIII receivers could become a reality.
Now that GWACS Armory has taken over production of the CAV-15 MKII receivers, E93 is once again accepting lowers for modifications. I recently had the chance to review a GWACS Armory CAV-15 MKII and came away surprised at how much I liked it. I probably wouldn’t have considered using an all polymer lower receiver before, but these are a very viable option, especially for specific applications. I was especially intrigued to see if E93’s mods would bring any additional functionality to the table.
E93 completed separate modifications to my receiver: the stock was shortened to approximate length of a collapsible stock in the second position out from the receiver (this includes fitting a new buttplate), the trigger guard was undercut to allow higher hand placement, the grip was stippled to offer a more aggressive grip, and a sling mount was added toward the front of the stock in the typical single-point sling mounting location.
My sling mount is a prototype and I do not have pricing information at this time but the rest of the package runs only $125 from E93 (or $85 to shorten the stock and fit the new buttplate). I think that is extremely reasonable given the quality of the work and when you consider what a new grip and stock might cost with a standard receiver.
I looked over the work when I first received the lower back from E93. The stock is cut cleanly and evenly. The new Pachmayr buttplate was fit well to the receiver. The undercut is executed very cleanly and evenly as well. The stippling is well executed with no voids or gouges. The stippled areas did show some slight discoloration but E93 told me this would happen and I know from my own stippling work that this will happen with lighter colored plastics. It was very minor and you would be hard pressed to even notice it now that the grip is dirtied from spending lots of time in my grubby mitts.
I tested the lower with a variety of different upper receivers. It spent most of its time mated with a Spike’s Tactical GMP upper. I liked this combination so much that it will likely stay this way as an iron sights only carbine. I also tested it with my lightest weight upper, a BCM 14.5” lightweight profile mid-length with a 13” Troy Alpha rail. The combination came in at just 6.65 pounds. That is impressive considering that this isn’t some stripped down lightweight build, this includes a free float rail, back up irons, Aimpoint, sling, hand stop and light! The E93 modified CAV-15 MKII lower shaved about 3/10ths of a pound versus a standard lower with collapsible stock!
The biggest and most noticeable functional change comes from the shortened stock. Joe was able to shorten the stock to the length of a collapsible stock in the second position which is where I normally keep my collapsible stocks. This shorter stock position works better for me when I square my upper body to the target and it is short enough that it works well with body armor.
The new rubber buttplate does a good job of locking the stock into my shoulder. It is still removable though not as easily as the original buttplate since the screws that fasten it to the receiver are buried in the rubber. I rarely, if ever, remove the buttplate so this is a non-issue for me.
The stippling has a fairly aggressive texture. It offers great grip without being too harsh on bare hands. It also works very well with gloves. The undercut trigger guard is a really nice touch. It makes it easier and more comfortable to get a higher grip.
The sling mount is very simple and I mean that as a compliment. Its simplicity makes it very versatile. It is a hook type sling mount that is bolted to a steel backing plate inside the stock. The mount is Melonite treated for corrosion and wear resistance. It can accept snap hooks or MASH hooks. I have a Blue Force Gear UWL attached to mine and it makes for a very nice combination. The location of the mount allows it to be used with either single or 2 point slings. This E93 sling mount is a vast improvement in both location and usefulness to the factory sling mounting point.
The undercutting of the trigger guard is well executed. The beveled edges of the undercut make the grip more comfortable.
These mods greatly improve how well the CAV-15 MKII works for me and the way I shoot. The quality of the work is great. The improvements are very functional. I am not sure what else I can say other than I consider the E93 mods to the CAV-15 MKII to be money well spent.
