B5 Systems SOPMOD Bravo Mil-Spec Stock - Coyote Brown
Note: these stocks are designed for true military spec receiver extension tubes, and fit tightly to eliminate wobble or pinching. On tubes that have been cerakoted or painted, fitment will be even tighter and some break-in time is needed before the stock will adjust more easily.

Ratings & Reviews

I purchased this item, but when it arrived it was practically useless. It barely fit onto a mil-spec stock and was so tight that it was impossible to adjust. It literally took myself and another man to get it off of the buffer tube. Just to make sure it wasn't the tube, I tried mil-spec BCM, Magpul, and Daniel Defense stocks, all of which fit perfectly fine.
A Top Shelf Stock from B5
Great stock. Mine installed easily on my Danial Defense MS buffer tube. It is a really tight fit at first but after using it for a week or so it broke right in and functions perfectly. There is little to no wiggle in this stock thanks to it precise tolerances. The cheek weld on this stock is feels so good as well. I feel this stock is a great choice for CQB applications, as you can really rest your cheek and keep it locked in during constant movements. The water proof storage tubes are a nice touch as well however I have not used them for storage thus far. The rubber pad on the back keeps the stock glued to your shoulder and what I really like about the most is that being so tacky, it acts as a anti-slip rest when the rifle is leaned up against a wall ensuring it will not fall or slip onto the floor. This is a nice stock packed with useful features. I for sure give it five stars.
Way too tight
by Chang -
Really wanted to love this stock, but it's got some issues.
The good: it's solid and no wobble and I like the lifted cheek rest.
The bad: It's stuck on my buffer tube.
This thing is super tight and I was hoping it would break in after a while but it's not going anywhere without the assistance from another person with gorilla strength.
At least this thing is now kind of like a fixed stock. A permanently fixed stock...
I have a black colored version and it doesn't have any fitment issues.
Does stock things.
No issues with fitment on my mil receiver extension. A bit snug, but I'd prefer that over loose. Added a little Rem Dri-lube. It's a stock, it does stock things. QD inserts work well and stock is easy to remove.

I was looking for a true coyote colored stock, and B5 seems like one of the few that have it. I have used the BCM stocks in the past and this seemed pretty similar dimensionally. I was however pretty worried based on the reviews that it would be too tight, but it went on easily. Literally no issue at all. The fit is great with no rattle. Great stock at a reasonable price.
It's a quality stock. Run it
by Jonathan M.
I've heard about this particular stock being super tight from a couple of sources. But I, personally, have not had that issue. I'm using an Aero Precision buffer tube, and it slides easily but it does wobble just a hair. But, in my opinion, it doesn't matter. There's seemingly tons of different stocks out there. Pick one, and run it.
Perfectly Rock solid
I started with a Magpul SL then the SL-K then back to the SL for the absent of the SL’s friction locking system. Why Magpul steered away from this is beyond me. Enter the B5 Sopmod. Smaller profile then the SL which is why I went with the SL-K. As rock solid as the SL, but superior. Why those are complaining for a stock that is “too tight” is beyond me. Isn’t that what you look for when installing a stock? Rigidity, size/weight, shouldering, cheek weld, anti rotational sling mounts, beats LMT’s price too by FAR. What con is there? Thanks PA!
