I've got QD on my AR slings and wanted to keep things uniform across platforms (as opposed to having a dedicated HK-style snap hook sling just for the MP5).

Plus, I like the clean, classic look of the wide (tropical) handguard for the MP5, so I resisted adding a QD mount via an aftermarket Picatinny rail. Similarly, there are numerous M-LOK and KeyMod handguards to which QD mounts can be attached, but again, I like the old-school polymer handguard.

As such, I've been looking for this QD sling pin for the past 1.5+ years with no luck:

Quick Detach Sling Pin for HK, Small, HK91, G3, PTR91, HK33, MP5, HKK-4818, RTG Parts

I'm not even sure if it is being manufactured anymore.

With that in mind, I decided to add a QD mount to the polymer handguard on my own. I considered these possibilities:

QD Micro Flush QD Sling Mount | IWC
Flush QD Sling Mount | NOVESKE

In the AR world, they both work very well when attached through polymer, but the minimal clearance room inside the MP5 handguard towards the muzzle could pose a problem. Between the barrel and cocking tube support assembly, it is VERY crowded, and I was worried that the hidden mounting hardware of these two options would ram into the barrel or cocking tube support (or both).

Meanwhile, I have had great success with this on my USC to UMP conversion:

PMM HK Universal QD Sling Mount (UMP/USC,G36,MP5k)

So I decided to see if it could be added as a modification to the MP5 wide handguard. Quite simply put, YES! It is a very simple modification, and there is barely any hidden hardware, so there is ZERO contact with the barrel or cocking tube support.

And for me, there is ZERO interference working the charging handle with or without the QD sling attached.

I tested both German-made (not shown) and USA-made handguards, and it works equally well in both. Just make an initial indentation with a sharp point so that the first drill bit won't drift on you. Stepwise increase the diameter of your drill bits from 5/64" to 7/64" to 9/64" to 11/64" to 13/64" to 15/64" so that each subsequent hole is concentric. The final 1/4" drill bit is perfect for the PMM QD mount as the mount has a neck that fits into the polymer that is slightly larger than 15/64" in diameter. Final fit is snug, and once assembled, the QD mount is very strong. An added benefit is that the final hole is 1/4" as opposed to 1/2" as in the first two options.

Yup, my rear QD is on the buttstock as well as on an AR-15 end plate. In Maryland, post-2013 SBRs have a 29" minimal OAL (with buttstock fully extended). As such, I had to use an AR-15 adapter (HKParts) with a BCM intermediate receiver extension (longer VLTOR A5 length buffer tube) and a MFT Battlelink Minimalist buttstock to get to 29+ inches. BLASPHEMY!! Yeah, but it's the best I could come up with.
