Great product
Just as advertised. Arrived in two days and assembled in just over an hour. Matched with an Aero Precision lower... nitride finish was a perfect match. Assembly required no special tools (allen wrench, drift pin punch) and was easy (except for that forward hinge pin knife to hold it in was the trick). Groups are 1-2 inches at 50 yards with a EOTech red dot sight.

My First AR Build - Looks Super and Shipped FAST
I was excited to find this perfect solution to my interest in building an AR Pistol in .300 AAC Blackout. I was told the perfect barrel length for this cartridge is 9” and this will meet that nearly perfectly with the flash hider in place.
I was prepared to wait the 5 or more business days for shipping, only to discover that it would be only 6 calendar days for delivery. Ordered on Wednesday, arrived on Tuesday, as Monday was a holiday.
Packaging is superb...well padded and double boxed. The lower build kit is also well packaged, with each component in a separate zip-loc bag, and everything packed in an oversized zip-loc. All packaging is clear, making easy identification of items. I also look forward to testing the Enhanced Polished armorer told me that this is a great upgrade for my build, and I likely saved myself from upgrading to a drop in trigger right away.
I’ll be completing my build and initial test firing tomorrow, and will be back with an update based on my firing impressions.
