OK, I wasnt going to say anything here primarily because those para things with AR butts are....aaa.... nothing I would own. BUT, this last picture, Now that is a stock I'v not seen before and the shape of it has me thinking who ever designed it had their collective sheet together. The bell grip and deep over cut for the thumb would put this stock to as close a REAL Rifle stock as you can get in a synthetic. I won a bunch of SKS stocks in an auction this past year along with 3 mint Russian stripped receivers. One of the stocks is an Advanced Technologies heavy black thing thats an atrocity to hold. Its at the bottom. Incidentally, at the top is a real fiberglass matt thin walled stock. I'v never seen one of those before. Anyone familiar with when those were made? A real odd duck.
So you say that nice one is a K-sport? I assume its cut for Chinese only?

Hi x, it's a Butler Creek stock with "K-Sport" logo on the wrist base medallion, originally on a KSI Parka-Para. It's one of the best SKS poly stocks I've used, and I've tried most. I think I still have a couple in black. The Butler Creek hand guards are quite unique as well. On the ATI monstrosity I have, I cut finger grooves in it to help "neaten" it up a bit and fit my hand better, but they're boat anchor heavy. They did come as an option from someone once.
I have one of those thin wall fiberglass units. It's here at the top rifle I built. It's mostly scrubbed, and I put a black Alby bayo on it to go along with the black bolt carrier and sling. The rifle below it is cut to 17.5" so I could use a neutered FSB without turning down the barrel OD. It's in a Black Butler Creek with a Choate no-vent HG and 5 round mag. Turned out pretty clean. Both those rifles were built on SARCO receivers with the last of my scrubbed parts.
BTW, I took that Para out of the T6 and found some nice wood for it

. The one on the bottom with a French tickler HG and a little different sling keepers. PAX
