Rendered the gun inoperable, but it's nicely finished - Texas Weapon Systems Century Arms C39/RAS-47 Gen-3 Dog Leg Scope Rail Top Cover

I recently purchased this to put on my psa AK-101. On the TWS website, this specific part number is meant for PSA, VSAK, and C39 AK's. I even contacted TWS customer service prior to purchasing to make sure this would be the correct model. Sadly, I never got a response. However upon installation, it drags severely on the bolt carrier rendering the gun inoperable. I can look at the bolt carrier and the dust cover and see where it's rubbing in two spots (one on each side). Aside from that, the machining looks nice and the finish is good. The instructions are simple and easy to follow. It's just a shame it doesn't work.
