Installation took a while - UTG Pro AR15 Carbine Length Drop-in Quad Rail with Extension

Bought this to replace the clam shell on my Bear Creek Arsenal. It took me about an hour to finally get it put on though. The bottom piece was NOT fitting. We had two people try to install it and finally I had to hit it with a hammer to get it to fit in place. That seemed to do the trick. I haven’t shot with it yet so I can’t say how well it will hold up but it looks nice, it has some weight to it. I’ve added some rail panels and a foregrip to it with no issues. Time will tell how it holds up.
