This high quality Bear Creek Arsenal barrel goes through its entire production life in Sanford, North Carolina at Bear Creek's facilities. Drilling, reaming, rifling, and turning are all accomplished on their CNC machines under ISO-9002 Quality Systems, allowing Bear Creek to put every barrel through a 100% inspection and air gauging process, ensuring every individual barrel is flawless before it leaves their facilities.

This 18", 1:24 rifled, heavy contour barrel is machined from 416R stainless steel, heat treated to RC 28-32 hardness, and properly stress relieved. Chambered for the heavy hitting .450 Bushmaster, BCA expects that it, along with any of their barrels 16" or longer, will hold a 1 MOA group at 100 yards when used with appropriate ammo and shooting techniques.

Deer Slayer


I purchased this about a month ago and just finished the billed.
<br>This barrel is incredible, it shot 1/2 groups at 100 yard with the 250 grain ftx. At 200 yard it shot 1" groups. I am using a lead sled to get the results. So guys if you are looking for a Deer slayer this is it.
<br>Just a short note, I purchased a bushmaster upper about five years ago
<br>it does not even come close to the accuracy of the Bear creek barrel.
