Knights armament Stock differences

[Mj30wilson900]

So I have noticed some differences in the complete lowers put out by knights and i was wondering if it is just a supply chain thing or different models.
The buttstocks have switched from lmt sopmod to the magpul moe sl-k. Can I buy a milspec moe sl and have it fit as tight as a factory installed one or does magpul mag a tighter toleranced sl-k specifically for knights?

Put any stock you want on it.

Yea I was just wondering if knights got any special spec stocks from lmt/magpul

No. The lmt buffer tubes are dry film coated but that rubs off quick.
