Great Value


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.

A must have stock for proper cheek weld


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.

Gotta try it!


Love it!

Love this butt stock

Its good


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

Great stock, awesome service from PA


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!

Happy Customer


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!

Great and excellent customer service.


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

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!

Awesome SOPMOD Stock


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
