Brownells Gun Tech™ Caleb Savant continues his survey of the B5 Systems stocks for the AR-15 platform. Today, the Collapsible Precision Stock is in the spotlight. You can easily adjust both the CPS’s cheek rest height and length-of-pull simply by turning the adjustment wheels. The wheels turn with distinct, tactile clicks, and once you get the cheek rest and recoil pad where you want them, they are reassuringly solid, with no play or wobble.
The Collapsible Precision Stock fits mil-spec (1.14″ O.D.) or A5-type AR-15 carbine receiver extensions (buffer tubes). Unlike a lot of precision stocks for the AR-15, you can extend and retract the CPS just like a standard M4 carbine stock. Move the little slider on the release lever to make the stock captive to the buffer tube, so you can’t accidentally pull it off when extending it. Don’t worry, the full extend / retract range is preserved.
More features of the CPS: QD sling swivel sockets on both sides, plus bars for simple thread-on sling mounting. M-LOK® slots on the underside are ready for a compatible M-LOK® monopod. You can get your CPS in popular AR-15 colors, including basic black, Flat Dark Earth (FDE), O.D. Green, Caleb’s favorite Wolf Gray, and a Brownells Exclusive, Multi-Cam.
B5 Systems offers the Collapsible Precision Stock with three different-sized cheek rests. The MEDIUM is for standard .223 / 5.56 AR-15s. Even with the stock fully collapsed, you’ll have enough clearance to operate the charging handle. The SHORT model provides more clearance for the longer charging handle of an AR-308. The LONG cheek rest is for AR-15s fitted with the Law Tactical Folding Stock Adapter AND/OR the longer A5 buffer tube. It gives you enough cheek rest real estate to position your head where it needs to be on the longer stock.

I have 1 on a shorty 16" .308 bolt gun chassis(long version), absolutely love it.
So, Long or Medium on an MDT Tac21 chassi, with folding adapter?
Does B5 clone everything from LMT or what?
Thank you, the medium was on sale, but I have a 308. Life saver good sir
B5 has great stuff
What abot the SFAR, would it be also the short??
holy shit thats ugly
What about an AR-10 with the law tactical folder?
Exactly the info I needed, Thank you
Where did you get that multicam medium? I want to buy it right now but I can’t find it, only the 5 solid colors. The other stocks come in multicam and the grips too.
What about medium on an A5 LR308 pattern?
Love the information on the stocks. Did you paint your ar wolf gray ? It looks awesome 😎. Thanks for the video.
Why did they get rid of the multicam and woodland camo schemes?
Expensive 😅
Everyone just trying to redesign the magpul PRS Gen 1 Stock because magpul is full of idiots
What about a AR10w/A5 system I guess your stuck between lengths
Have you tried the Magpul PRS yet?
Gosh… maybe instead of short, medium, long they should have just said 308, AR15, Folding,.. something ain’t right when you have to make a video about this.
Love B5,glad to see they’re thinking not just putting stuff out,unlike some other brands.
Good stock but it lacks shoulder purchase area and the butt plate isn't adjustable for height or cant like the Magpul PRS Gen 3. I ended up replacing the B5 CPS with a PRS Gen 3, a world of difference in terms of dialing in your fit with a rifle.
Right side charging handle is the way Togo!
Restock the multicam on brownells please my ar10 needs it
This vs the magpul lite
Question: with the Long you recommend on the A-5 tube, wouldn’t the charging handle movement be hindered by the cheek piece being moved further forward in the fully collapsed position? Right now my charging handle has only about a half inch to an inch clearance from the cheek piece on the Medium length with the stock fully collapsed. I do see what you mean about your cheek position but couldn’t this be improved by adjusting the LOP?
Yes, but is there clearance for the charging handle when using the "long" version, fully collapsed, on an AR-15 with an A5 tube that isn't using a Law folder?
I learned something, Thanks.
the magpul precision stock is nice, but it feels just a tab bit to long over all
I have collection of stocks both in Bravo and Sopmod and all of them have a side to side play on a Milspec Carbine buffer tube (both DD and Geissele). How is the side play on this one?
Damn. Multicam sold out
Wobble like hell on buffer tube
Explanation style is very clear to catch….
just my experience. I put a law folder on a 308 ar 10, and it snapped the "button" off from excessive recoil, causing it to just flop around not being able to lock. while law tactical sent me a replacement part free of charge (boss move) i would recommend using it on calibers smaller than 308 for the time being. some constructive advice id give is beef up the locking bar/latch area, once that breaks, the rifle is pretty much disabled without a quick fix. so far has been super convenient on my ar15 tho, no problems to report there. can't wait to see the law tactical folder sequel!
Will the medium fit on the POF Revolution and Ruger SFAR
I would add that if you are putting the stock on a bolt gun, like a Ruger Precision Rifle, go with the long.
The one I played with was a little rattly on the buffer tube. It seemed to me that the wobblyness of the stock kind of defeated the “precision” purpose. YMMV.
Oooohhh! I love the B5 Bravo stocks and might have to give this one a try for my more precision setups.
I see PSA is selling some on their lowers is that B5 systems any good
Thanks for the info on the differences in sizes. I checked their website and couldn't figure out why they had 3 different versions
Definitely looks like it might be a Magpul PRS Lite killer.
When is B5 gonna make a multi-cam grip ?
I love how the closed captioning opens this video with “Hi, Caleb with brown eyes here…”
Damn I need one of each in Multicam!
