The nitty gritty details about the PMM Sling Mount
« on: January 17, 2018, 08:36:43 PM »
Our Outlaw 3-Gun match requires our rifle to be mounted on a single point sling. This is because we transition between rifle and pistol often and the gun club wants the rifle muzzle pointed straight down when slung, not off to the side.

The PMM Sling Mount is perfect to accomplish this on the Scorpion Carbine. The sling mount comes in a left and right side version. I now own both and wanted to share the nitty gritty details about them.



This is the left side sling mount on the left side of the receiver. This was the first version that I purchased

I have two very minor issues with this setup

a. My nose sometimes touches the sling swivel because it is so close. I have the OEM folding stock and keep it in the middle position.

b. The sling mount obstructs the ability to remove the folding butt stock



This is the right side sling mount on the left side of the receiver.

This configuration places the sling swivel further from the butt stock so no more nose touching the sling swivel. The butt stock can also be removed now.

A few more nitty gritty details

The sling mount screw requires a T-10 Torx Screwdriver (not included)

If you install the right side sling mount on the right side of the receiver, the folding butt stock will not fully close by more than an inch.

If you install the left side sling mount on the right side of the receiver, the folding butt stock will not fully close by just a fraction of an inch.

The product is extremely well made. Super fast shipping. I just wished I knew the above issues before placing my two orders.

Here is another...We had a customer at my shop with the same rear mount as depicted in the original post. His factory sling attachment point cracked off the receiver! Now this sounds like it could be a CZ issue, but if the pmm sling mount was not in place then it may not have occurred. With that being said I think PMM makes very awesome products, but I am considering an alternative for QD mounts on my personal scorpion.

Oh the icing on the cake in this scenario: CZ was quick to send him a replacement left receiver half, BUT little did we know he had an earlier model gen 2 and they NO LONGER make the older style receivers (like I have on my gen 1 also). Cool usually no big deal right? You send the gun in and they replace it and you get a new gun....nope won't work because he has a pending form 1! I felt bad for the guy. Hes already been waiting months. So my gunsmith just grinded the cracked portion flat and he will live with it.

Something here to consider!

I was just starting to think about sling options and was leaning toward the PMM mounts.  I was wondering if that rear point could handle the stress. 

Anyone else have one of these break?

The mount no, the receiver yes. I haven’t done it yet but I’m going to dremel it flat and just use the QD on the tail hook now.

bleep, I never considered that the receiver might break. I love my PMM QD mount. I hope mine doesn't break.

Breaking off the plastic mount was my first thought with that PMM mount.  Same scenario with a registered receiver.

I believe you hit the nail on the head, the original receiver loop is intended for a sling hook which would exert pulling force rather than 'prying' force when this QD mount is in place with the sling in full tension.  Try break off a plastic tab of anything by pulling that would result in nothing, but if you put a screwdriver in it a leverage off, the tab would break.

An alternative solution is this QD mount that clamps onto the upper rail https://www.strikeindustries.com/shop/ambush-sling-loop.html
I have 2 on my Kriss Vector for 2-point sling.  There are 2 sides, one with QD socket and the other with a loop. The loop for hook type sling mount can be cut off if you don't want it.

Always learn something new here!  I like the looks of this design, and I thought I saw them all coming from the world of AR 3Gun.

Looks well made, but not a good idea IMHO. I see they tried to match the contojr of the reciever on either side of the mount, but the fact is tbat any side load is putting a moment arm load on the reciever stud/mount. Not surprised it could snap off easily. I wouldnt use it for anything other than carrying the weight of the gun as-is.

Uhh, yeah, I know the company is called Strike Industries. My question is are they trying to be cute and model their SI logo ofter the SS insignia, because it kind of looks like it.

Way to derail a legit thread! Ever hear of Runes??? Maybe do a little research next time before making an assumption...

Anyway...

So...concern over the PMM mount causing the receiver to crack...aren't these points that the PMM mount attaches to MEANT to be used for sling mounts???

I haven't stressed my PMM mount but I plan to do so in the very near future so we will see...will report back if I have any issues but I don't forsee that being the case.

Oh, boo hoo. I asked a question. I didn't declare them to be the 4th Reich.
