Good with some defectsReview by Lincoln Meissner

The tolerances are phenomenal and this is a very well machined piece of metal. That being said, the detent for the rear takedown pin is too big to fit in the threaded hole. I don't know if this is from the threads or the hole is too small, but the detent I have is now stuck. The front detent hole is perfect and I had no problems installing.

Secondly, the rod for the ejection port cover is too long and prevents the barrel nut from screwing down flush. It had to be trimmed.

If they notated that a smaller rear takedown detent would have been required, and trimming would be required on the ejection port cover rod it would have been a higher rating. (Posted on 7/22/2016)

This is a great looking lower/upper receiver! Tremendous and beautiful craftsmanship. Having that said it was a pain to install the lower parts. Installing the mag catch was a bit tricky with the detail of the lower but nothing more difficult like installing the rear take down pin. It was very difficult, I lost 2 springs and when I finally got the screw to go in and screwed all the way down the take down pin wouldn't move if my life depended on it. I had to trim down the spring for it to fit with the set screw installed (Called Rainier Arms for this). Honestly I think the take down/pivot pins should come included with the lower/upper due to this difficulty like the Mega Maten does. Once I was done though, it looks great!! I am probably not going to build another AR-10 but if I was I would get another one! (Posted on 7/5/2016)

Fantastic base for your heavy metal gunReview by Jason

Built a 3 gun 308 with this and the fit was perfect. The tolerances are spot on and it has functioned flawlessly with no special fitting required. In the AR308 market it is always more difficult to find parts you can fully expect to fit and function the first time, this set is a part you can count on.

One note - the dust cover door is not included as shown in picture (not a big deal) (Posted on 6/29/2015)
