Product Info for Brenton USA Guide 18in .300 AAC Blackout Upper Receiver

Limited Series rifles are Brenton's specialty rifle family and are more purpose driven in their design. Limited rifles are available in Midnight, adjustable stock configuration only and include Black Nitride carrier and bolt components as well as a 4.5 lbs single stage mil-style trigger. Limited series rifles are for the rough use, bounce around in the back of the 4x4 kind of hunter.

With its .30 caliber diameter, the blackout has captured the hearts of many hog hunters. The 110 gr. Barnes and Hornady copper bullets perform very well in this platform.

The 300 BLK was approved by SAAMI in January of 2011 after living another life in the wildcat community as the 300 Whisper. The shooting public in general, picked up on it almost immediately as an inexpensive way to put big holes in paper. Only later would it turn into the fine hog hunting round it is today.
