Good lower. Only slight issue I had was the trigger guard install. Used a FCD winter trigger guard, and I had to tap it in with a soft faced hammer, pretty hard actually. Anodizing on the lower or trigger guard may have been a little too thick, but it’s not like I’m ever going to take it off. Non issue for me.

I could have purchased this lower from three different vendors. The reason I chose Rooftop Defense for the lower wasn’t because they had the best price online, it wasn’t because their staff were very professional and polite, it wasn’t because they shipped my lower the moment they recieved my FFL’s information while I was literally still standing in the gun shop. It was because the Ramen.

Sol & Co. are the best in the business, hands down. Better than competitive prices, fast shipping, the occasional call to ensure your purchase is on the way, and the RAMEN!
As for the lower, I cant begin to say how nice it is. Yes, I could have got tje MARS-L, but this is perfect for a lightweight CQB/Pistol duty build.

Great lower. No WC concerns as other reviews have noted. Excellent shipping times from the rooftop team!
