Genuinely so happy with this lower and with Rooftop that I may have to order a 3rd one…by far my favorite website to do business with now, and I will be telling everyone I know how great they are.

Quick service, great product. No blemish found. Love the angle of the BCM grip. The stock adjustment toggle is stiffer than the Magpuls and MFTs I’ve used in the past. I feel like it has less positions too (am I imagining that?) so I had to settle for slightly lower LOP than I normally would run. My first time using the BCM gunfighter trigger. 5ish pound pull weight with very little to no wall, which will take some getting used to since I’ve spent years using the 2-stage MBT triggers. Most of all, can’t beat the price on this complete BCM lower. Super thankful for Rooftop Defense for keeping these stocked and saving me $50 compared to a standard BCM lower. It’s battle ready and “blemished” is really just a formality. So happy I can finally put together my dream AR build with this lower. My 3 year old loved the noodles.

No blem to be found. I ate the ramen.

Could not have asked for a better experience. Top Ramen was on point and communication was even better. The “blem” lower was perfect with no issues I can see. Will 10/10 always recommend Rooftop to anyone who asks!
