    This product is awesome on my M4 Gives me great control. Highly recommend it! After all the stocks I have played with, this one certainly takes the cake. It's very rugged and the recoil pad has superior surface area as compared to the Magpul STR. I won't ever put another stock on my rifles unless it is one of these.

    My first one, but more to follow. It's just a simple good design. Cheek weld is awesome and feels like a pillow. Better lock up than many other stocks. Back to back with my friends lmt, this is a far better value. Save the 100 bucks and get a second b5.

    sopmod b5 fde stock

    Best bang for your buck!!!!! Best stock I ever held on my hands! The feel on it is very sturdy, strong Polymer, and no wobbles on your buffer tub either. The fde is a bit lighter shade of color compare to magpul fde. But overall very satisfied with the purchase and highly recommend it if you want to build any BLOCK 1.5 / block 2 / mk18 / mk12 / MK18 mod 0 and etc.

    I'd been on the search for one of these in FDE for quite some time. Nobody had them.. ever. Finally the other day received the "In stock" email. I couldn't be happier. Amazing quality. The most PERFECT match to my FDE ERGO grip and FDE Magpul furniture. BCM service and shipping were incredible. Class act BCM! Thank you!

    Magpul/LMT killer

    Extremely comfortable cheek weld, with no seams to snag the whiskers. Butt pad is just right.
    Tight, smooth fit. Was planning to add weight in the storage tubes just like the other review, to improve balance.
    This FDE is somewhat lighter in color to Magpul and others, so if you have to have a Garanimals Rifle, just oil and grime it up and it will darken over time. Cant beat BCM's price and shipping speed! Got it in 3 days.

    Nice Extra-Comfort/Weight Option

    With my carbine's Socom barrel, and MOE stock, the extra weight forward of the magwell was a bit too pronounced. So I decided to replace the MOE with the B5 because it's about 3.5oz heavier & it provides a nice beard-friendly cheek-weld at half the cost of LMT's.

    The stock is VERY tight on the buffer tube, but AR stocks here in CT have to be pinned anyway. Problem is, pinning it onto a buffer tube permanently seals the storage tubes. Not wanting the storage to go to waste, I decided to add just a tiny bit more weight in the form of two 5/8" delrin/acetal rods. I measured the tubes, cut the rods & flanked them with felt AR chamber stars to prevent them from rattling. It was a bit of extra work figuring all of this out, but in the end Im happy with the results. The weight of the stock now is near 15oz which gives it 1oz over Magpul's ACS (PRS is 27oz). The rifles balance point is now at the center of the magwell & not at the delta ring, which is in fact a perceivable difference.
