Aero Precision gets high points for this Bolt Carrier Group. BOTH function and finish were flawless...!!! The action moves without any points of hesitation and the ejection is positive. I will buy this again for my next build.
Great purchase of a great product. Packaged and shipped appropriately and the product arrived undamaged. Also, great prices and customer service. This is one of the few places where you can use multiple gift cards for the same transaction.
Fast shipping, great service. bcg seems top notch quality. Haven’t used it yet but will be perfect when my build is finished. Thanks AR15 discounts!!
