B5 SOPMOD stock,coyote


Bought this because i wanted a SOPMOD stock with the anti rotation QD swivel mount and in coyote color to match the KNIGHTS ARMAMENT taupe color panels that i have( URX 3.1),color is more orange or red( like clay) ,does not quite match.stock fits fine on a BRAVO CO. buffer tube,not tight but not loose either.the stock is perfectly fine except color,for me.

Great stock even better customer service!


I already had a couple of these stock and if you are buying one you probably already know what it is and why you want one. My review if not for the stock itself, but the customer service. WOW! These guys process and ship orders FAST. I've placed several orders with them and I've gotten everything I've ever ordered on the 3rd day after placing my order. Order on a weekend or Monday, get it on a Wednesday. Order on a Wednesday and it will show up before your weekend shooting trip. Very impressed! Also I find that most of the prices beat other dealers. If they don't (EOTECH's for example) they throw something in for free.I always check PA first now. I do hope they keep expanding their parts inventory though. Would love to see more KAC, Noveske, BCM parts etc.

Great item and fast service.


I got my stock rather quickly and with no issues. It is a very good quality stock and is much better than the regular one. My only issue is that it is a very tight fit on my buffer tube, most likely the size of the tube is a bit off. I can get it to adjust but, it is a lot harder to move than it should be. Once I slide it back I have to smack it forward to lock it in position.



What more can I say, I love these stocks and the cheek weld they provide. Nice and tight, no wobble fitment also a plus.

nice stock


worth every penny

Check weld for days.

I really like this stock. The cheek weld is amazing. It really allows you lock into the stock and is super comfy against the cheeks and more importantly does not pull out beard hairs! It is a really tight fit at first but after 50 to 100 manipulations it loosens up and settles in just fine. It is not a loose fit at all even after the break in. The storage tubes provided are excellent. They are o ring sealed making them water proof and I keep a bore snake, q-tips, a small vial of oil, and 5 Remington gun wipes in mine. The storage and fit are great but what I appreciate the most about this stock is the check weld, you have to experience to really know just how awesome it is. Negatives? Nope.
