Extremely well built, this is a piece of art! Lighter than expected. This will be an excellent piece of a tool to add to the tool shed

Absolutely love the quality. The LRBHO feature is a very nice touch. Very lightweight as well!

I would have given it 5 stars but it came in an unmarked box with a packing slip. For the price I paid I expected at lease a decent box with protective foam. Not that the other plain box was not packed well. Just expected something a little nicer. Lower looks good. Trigger has a bit of creap/ mushy feel but breaks clean with a short reset. Very happy with the product. Runs without issue with my upper.

Extremely well built and works flawlessly with the Angstadt 6” upper I had previously purchased and used with a Colt lower. I like that I can now use Glock magazines.
