What is the difference between buying the stock alone and purchasing a separate, mil-spec, mounting kit (like at Bravo Co. USA) and buying it as a set, i.e., stock with mounting kit (From LMT)?
Thanks.
a little dry film finish, and cost (possibly?)
You pretty much answered your own question.
You either get it as a kit, or you get it separately. If all parts are from reputable vendors, there really isn’t a difference.
That’s what I figured. But, you never know. Blindly assuming can be expensive.
Thanks.
There is a HUGE difference and for many including myself, the Sopmod stock isn’t nearly the world beater it currently is w/o that paired LMT RE…I cannot stress how much of a difference it makes in terms of the pull or feel of the stock, as well as completely reducing all movement when shouldered, and in general has far less “slop” on the tube.
Bottom line is that the kit yields not just the awesome sopmod but the true “hydraulic” effect that is referred to by many of the folks who love these stocks.
Its honestly “hydraulic” when adjusting on the LMT RE that it was originally designed to run on. It’s also worth noting that the LMT RE is clearly the best RE made to date as a stand alone component. I welcome a challenger on that rather bold statement I made since I believe it’s that much more well designed and built. Normally I wouldn’t make a bold, and rather unsubstantiated claim but I’m supremely confident in that statement 
Besides LMT obviously putting the “kit” or total package on their rifles, KAC runs it as well on all their SR15 IWS’s. The sopmod is a great stock on it’s own…it’s one of kind, and truly an awesome piece of kit when run how it was designed to be run with the associated RE.
+1 on all accounts.
There is absolutely no play in my SOPMOD with my BCM RE.
I can understand wanting to get the stock with the kit thats made to run flawless with the stock and have a real good fit and finish made to be paried up with that stock. It’s like I wouldn’t want a Mopar Hemi engine and then put on chevy heads …LOL just some early morning humor. If you need to get everything thers really no point not getting the kit…
Normally I would agree with you dude. But the KAC/LMT extension I had measured EXACTLY the same diameter wise as a Colt one I had on hand, and a friend’s BCM one.
Also… my A5 extension just came in. There isn’t any play on that either. It’s fucking solid.
Other than that. Bravo. Totally correct. If the A5 works well, I’ll say you’re wrong about LMTs RE being the best.
But yeah, SOPMODS are the end all-be all stock for me.
I have Stag mil-spec RE on my rifle and installed a LMT RE on my Dad’s rifle and feel no noticeable difference in how my LMT SOPMOD stock fits on either. The amount of play is exactly the same and they do not lock up any different. My SOPMOD fits them both like a glove. I originally purchased the LMT SOPMOD kit but ended up putting the LMT RE on the other rifle. The only real difference i could see was the dry film coating.
I purchased just the LMT SOPMOD stock (not the complete kit) and regardless of where I position it on the receiver extension it rocks like it has a hinge on every gun I own.
I guess it’s the luck of the draw as some have had good luck with just buying the stock but buying just the stock didn’t work out too well for me. If I could do it over I would buy the complete kit. For half the price I have had great luck with Vltor IMod’s.
There is no play whatsoever on my Colt LE6940 using the SOPMOD. The only downside is there are only 4 positions on the stock Colt receiver extension versus 6 with the LMT (or KAC) version.
All that said, I’m less sold on the necessity of a $175 stock than I was at one time. I swapped the SOPMOD out on my SR15 and have been using a CTR and am equally pleased with it.
Disagree.
The aboslute ultimate would be the SOPMOD on the A5 RE.
I’d run that on every slider I owned if the SOPMOD wasn’t so absurdly overpriced.
and so it begins…
I have one of mine set up that way and the others with the CTR. Both fit as expected and I don’t see changing this any time soon.
I have the black KAC (Made by KAC or LMT?) and LMT RE’s and both are equally smooth inside, though there’s nothing hydraulic about it. 
The inside of the Vltors seem to be a little less fluid, but they work great, actually better for me on every gun I own.
Generally cheaper.

What you said WAS utter nonsense.
