I ordered the Strike Industries Modular Fixed Stock Extended Rubber Butt Pad so I could use it on my Strike Industries Modular Fixed Stock that I ordered at the same time from Wing Tactical. Shipping time and delivery were great. Both items arrived as ordered. Love the fixed stock! Installation was easy. When I tried to install the extended rubber butt pad, I noticed it was warped top to bottom. Not flat like it should be... Just a gradual warp. I noticed it was warped when I took it out of the package, but it's really noticeable when you go to install it. A clip is molded into the top portion. You insert the clip into the top of the fixed stock and install a screw into the bottom portion of the fixed stock. When I screwed the bottom of the butt pad flush to the fixed stock, the upper portion of the butt pad bowed out and left a sizeable gap. Definitely a beard grabber if you have one. It was also putting enough pressure on the clip to bend it. I was afraid it might snap off at some time. The screw was only snug to the bottom. Not over tightened. If I backed out the screw so the top portion would be flush, the the gap appeared at the bottom and the butt pad wobbled badly. I removed the rubber but pad and put the thin butt pad that came with the fixed stock back on. Other than the warp, the extended rubber butt pad is well made and there is no over hang anywhere when lined up with the fixed stock. I really wanted to use the extended rubber butt pad because it made the LOP just right for me. At the price of $13.95, it's not worth the hassel of sending it back. I will probably just order another one and hope it's straighter. This is not the fault of Wing Tactical. They had no way of knowing the rubber butt pad was warped. I will continue to purchase from Wing Tactical and I like Strike Industries products as well. This particular extended rubber butt pad must have slipped past QC. Disappointed that I coulden't use the extended rubber butt pad, but I'm happy with fixed stock. Wing tactical has many great products to offer with good prices, and shipping was spot on considering the state of things with Covid and high demand for products.
