Monday I stopped by a local fun store I do business with and picked up a standard S&W M&P 15-22 (Threaded barrel). I've been meaning to grab one for a while. While at the store I buy a Magpul MOE stock and a MIAD to add to the rifle. I have a MIAD AR -10 grip wedge on the way that I ordered online. No sooner do I get home, that I see a magpul version of the rifle is now available with the accessories I purchased plus MBUS sights. Well, I was a little mad at myself for not knowing this ahead of time. I could have saved a little money. No big deal, though. But what I did notice is that the Magpul version also has ambi QD sling swivel cups mounted at the back/sides of the lower receiver near the fake buffer tube. That is an add on I'd really want (for a single point sling). I called Smith, and they said they didn't install those. They thought Magpul did.
I intend to email Magpul, but if they or anyone else read this post and know the answers to the following I'd appreciate it:
Does Magpul sell the QD cups that they are installing (if they indeed are doing the installation)?
Is it as simple as drilling the correct sized holes for installation?
Will Magpul be offering installation as a service for those who send in their receivers?
Do the QD cups bolt in once the holes are drilled or are they glued?
