I bought the complete LMT SOPMOD from
Quantico Arms at the Fort Lewis, WA store. They rock!
Their cost is $236.00 for the complete stock kit.
I bought the Choate 16-01-04 mail order from Choate. Excellent service, shipped
to my door in 4 UPS days. Their cost is $135.00 for the complete stock kit.
And now on with the show....
Both laid out side by side disassembled.

Both are well made, a bit of overmold
plastic on both. No big deal.
The Choate buffer tube is longer, but the inner length is the same.
The differences between the battery storage compartments is obvious (or it
should be).
The LMT butt stock is made of plastic while the Choate butt stock is made from
both metal and plastic.
On the "bottom" piece where the slide release is the Choate is made of metal
that's been put into the injection mold (near as I can tell) and the plastic was
injection molded around it.
This has resulted in the Choate stock weighing (calibrated elbow) about 1/3 more
than the LMT butt stock.
I am keeping the Choate, and if I were building another AR15 I would not
hesitate to buy the Choate stock kit and use it.
Buffer tube follies....
