B5 Systems SOPMOD AR-15 Polymer Stock with Quick Detach Mount MIL-SPEC - Black

I've had no issues with two of these stocks. They are very solid and have a great cheek weld. I was very impressed to see the storage tubes utilize two separate o-rings to seal. It's also nice to see the tubes can't come off without dismounting the stock from the buffer tube. It ensures you won't lose your tubes or batteries in the field.

This stock came highly regarded, ive read all the great reviews and i have been waiting to order this stock for a few months. Im glad everybody is happy with their nice tight stocks, however my stock was a huge disappointment. My stock is very loose, even when its collapsed all the way. It is just in general terrible quality feeling when your holding it in your hand, i honestly think it is an airsoft knockoff. The stock came in retail packaging. I also purchased a vltor modstock for around the same price $100. Now THIS is what a premium stock should look like, and feel like. Locks up nice and tight, fit and finish is what i expected in the b5 systems stock. I have never written a review before, but i figured i needed to share my experience. I would NOT buy this stock again, nor would i reccoment it to anyone, certainly not for $100, it just feels like a $40 stock.

Picked this up on sale and couldn't be any more satisfied. I own the Bravo and Enhanced versions and they are quality products. I have an LMT sopmod and really can't tell the difference between the enhanced and the LMT. It's just as good and priced right. I like tight fitting stocks. It's really snug the way I prefer.Also, I'm also always surprised how fast PA ships. Like all other owners we don't like waiting for parts. PA ships quick and they package items well. Thank you!

This is an awesome stock if you like the cheekweld and cargo carrying capacity. Only drawback is you have to take the stock off the buffer tube to access the storage compartment

Nice, fits tight, like the battery compartments... it is a little heavy.

This stock is awesome. Unfortunately when I first recieved it I was only able to just barely get it on my buffer tube, and it required the use of a hammer to remove it. I contacted PA support and they quickly sent me a return label and RMA number. I returned it and a few days later I had recieved confirmation of my RMA and a new stock was sent out and arrived at my door just a few short days later. Everyone at Primary Arms was on point helping me out. This wasn't my first purchase and will not be my last. I have told co-workers about my experiences and super fast ordered-shipped times (less than an hour) and they all want to order from Primary Arms for their next purchases. Stay classy Primary Arms.

Great stock! the only down side is that it is a little on the heavier side (thats why i give 4 stars). with that said... Very sterdy, no movement, allows for a comfortable and nice check weld. Other then the weight, I love this stock and PA.com sent this out super fast!!! Great company to deal with...

Prompt service and easy to deal with customer service. Will continue to buy from Primary Arms.

I haven't finished building the whole rifle yet but I am impressed with the B5 stock and I am very anxious to take it to the range.

Great feel and easy to get a consistent check weld on.

Love this butt stock

Great stock, whole order shipped the same day it was ordered. Had the stuff I needed in less than 2 days, couldn't ask for better service.

Love it!

Great stock. I've always loved these type of crane stocks, as they provide a great cheek wield. It's solid and battle proven. I currently have it on a Block II clone and will not be taking it off. Only complaint is that it does slightly (and I mean very subtly) moves when pushed against. However, it stays rock solid when shouldered and runs like a champ. Also, its a great deal for what you get.

Very nice slim line look with added storage compartments. Comparable to a Magpul STR but cheaper and lighter.This stock is a STR and CTR hybrid

This is my 3rd build using the B5 systems SOPMOD stock. Fits nice on the buffer tube and more positive feel when shouldering my rifle to my cheek.This was my 1st time having to buy from Primary Arms and I couldn't have been more pleased with their service and fast shipping. Items ordered were exactly as described.

PA had the best price on the Enhanced SOPMOD stock. It was exactly as described! The last place I tried to order an Enhanced SOPMOD stock from, sent me the Bravo instead. PA shipped the very next day and I had it 2 days later. Thanks!

If you plan on using optics on your AR, then stop and buy this stock now. The best stocks for this purpose are the SOPMOD and the VLTOR. But unlike the VLTOR stocks the B5 SOPMOD does not rip out your facial hair. And if you are a manly man, you definitely have facial hair.

This stock came highly rated so I figured I woudl give it a try, I am used to the Vltor Emod but it is over priced so when I saw the price of the SOPMOD I had to order. The only issues I have with the stock are that the stock is wayy too snug on the buffer tube to be effective. I have to take the rifle out of my shoulder to be able to adjust the length and the battery compartments on the sides which i will most likely never use are basically usless. You have to remove the stock off of your rifle to access them.

Got my items extremely quickly and everything was exactly the way it was presented online! Awesome prices too.

I own an LMT SOPMOD Stock, and can not tell the difference between the LMT and this stock that is priced at about 1/2 to 2/3 (I got this stock on sale) cheaper. Great value and the B5 stock holds a tight tolerance. Don't waste your money purchasing more expensive stocks.

Very rugged & the real deal at the best price around.

Shipping was fast as always. I received this stock and immediately put it on my mil spec reciever tube and noticed it was one of the toughest stocks to get on. The fit is so tight that I'm not able to adjust it without struggling! To some this may be a negative but to me I loved it! I don't plan on adjusting it all the time so it's not a big deal. I will be purchasing another one of these for my next build thanks primary arms for always taking care of your customers!
