I purchased this magazine for use in my Daniel Defense DDM4V7 in order to gain a little more room under my rifle while bench resting at the range and for use with my "grip pod" bi-pod which doesn't have enough height to clear a 30 rd mag when just setting the rifle down to rest on the bi-pod. So far I am really impressed with the robust construction and performance of these mags. I have over two hundred rounds through these mags so far with zero issues. I also like the fact that these mags seem to jump out of the gun when ejecting. Even with the rifle in a horizontal position the mags fall free of the magwell nicely. I purchased the FDE version and they are slightly darker than the Magpul furniture on my rifle but its not enough to notice. All in all Im very satisfied with the product and with the sevice from Tacticallink!
