Brownells USA Excellent Product 08/11/2016

Purchased this item for use with a dedicated .22lr build. The extra large ejection port increased reliability. On the occasional jam, I was easily able to get my fingers inside to clear a spent .22lr casing. Fit and finish are good, and this product was exactly as expected.

Brownells USA Solid 09/06/2016

I bought this for my latest AR build. I have an Anderson mil-spec lower. The biggest moment of satisfaction or disappointment in my mind is when you slide the upper into the lower and bolt it down and give it a good jiggle.







When I put it in, it gave that nice, slow slide, where both receivers are making contact and it makes that ever so subtle "shish" sound as you slide it in. PERFECT! Pushed the pins in, give it a good rattle and no clanking or anything. No light shining between the receivers. So happy I got this.







Plus, the billet build and slick side configuration gives it a real nice look and feel to it. Very happy with my purchase.
