Felt cute, might delete later…

I’m in love with Magpul’s MOE SL-K stock, which I picked up from Brownells UK. It could be a fleeting crush; I may go back to the Magpul CTR of V2.0 of this build (now you see why I use version control).

However, right now this just looks and feels right – so I’m just going to go with it.

We’ll come back to the stock later, but what else is new in V2.1 compared to the previous version?


I changed out the Magpul MS3 sling for TacBelts’ take on the Way of the Gun Sling. This also necessitated removing the Magpul RSA.

I’ll keep the MS3 just in case I want to go back to it, but this twist on the sling made legendary by Obi Wan Nairobi really has my interest right now. It’s also made by one of the nicest guys in bespoke nylon.

The sling utilises silent, flexible paracord loops. The muzzle loop is kept from slipping by picatinny:

The butt loop is wrapped around the existing ASAP:

I’ve also tidied the Element LA5s wiring by utilising a Manta Cross Clip on the right side, front picatinny segment:


Now, back to that stock.

The MOE SL-K isn’t very much like any stock I’ve tried before as it’s so compact and minimalist. The only thing close would be the OG CAR stock. My full review of the SL-K is here.

Here it is compared with Magpul CTR and ACS stocks:

Also note that I’m now running the stock a lot further out than in previous iterations of the blaster as seen in the blog. I actually started doing this with V2.0 of the build (CTR stock) and it works really well. I picked up the idea after reading this article by Frank Proctor on SSD.

As for my justification in pairing the SL-K with an L119A2; it’s down to my favourite process: functional personalisation.

So, there’s a lot more going on than just the look and feel – although that clearly plays a huge role:

  1. The MOE SL-K is way cheaper than standard Magpul stocks – something like half the price
  2. It’s significantly different to stocks we’ve seen in reference pics (CTR and ACS) because of its form factor
  3. Stocks are easily replaced without armourer intervention
  4. This stock can be easily bought from Brownells UK

With all that said, I also think of Magpul items as having carte blanche with UKSF – which probably trumps all other considerations.
