Looking at replacing the stock on my 10.5”. Doing some shuffling and the current one will go elsewhere

I’m deciding between (possibly) the Magpul SL or the SL-K PDW.

Leaning toward the SL-K PDW just due to the size. It’s my smallest rifle and keeping it small with the same features sounds pretty cool and my son (8) uses the rifle a lot with me and the smaller size would help him

Anyone use this before? Any pros/cons, loves/hates? Only thing it looks like instead of an integrated QD socket, you’ve got to use an MLOK detachable socket on the K for a sling
