Quality & The Vibe.
I’ve bought not one but three of these uppers. Redoing my arsenal with more of a general purpose rifle goal. I bought a carry handle to go in my bag by I run ACOGs with a piggyback RMR. The visual is perfect - I was Immediately satisfied. Definitely worth the money and week wait. For us cheese grater, GWOT, SHTF folks - this is it.

Great product
Very happy with this receiver for the money. Took a little while for the product to ship due to the virus and politics affecting the flow of parts but thats no fault of TNTE. Overall very pleased and will be buying more products in the future.
