Magpul MOE lower kit
Great product for the price. Assembly was painless. Only request would be to add a spare detent and detent spring (you know you lost some before). I will definitely be looking to this company for other parts.

Lower build kit
The lower build kit was exactly what I wanted! A great price for what you get! The reason for 4 stars was the fact it was ten days for them to box it up and then five more for shipping and then blame it on corona! I ordered two lowers on the same day and received them in 4 days from another company!
