Getting My Hands on the Spikes Tactical 300 Blackout 16in Medium Profile Rifle Barrel, Stripped
The Spikes Tactical 300 Blackout 16in Medium Profile Rifle Barrel, Stripped promises a blend of durability and performance, catering to shooters who demand reliability from their AR-15 builds. Spikes Tactical has a reputation for producing solid, no-nonsense components, and this barrel appeared to be no exception. Its .300 Blackout chambering opens up a world of possibilities, from subsonic suppressed shooting to supersonic hunting rounds.
I’ve been itching to build a dedicated .300 Blackout AR for some time, primarily for hog hunting in thick brush where shorter distances and suppressed shots are paramount. I was searching for a barrel that balanced maneuverability with ballistic capability, and the 16-inch length seemed ideal. After reading about the Spikes Tactical barrel’s construction and positive reviews regarding its accuracy, I decided to give it a try.
Upon unboxing, the barrel exuded quality. The Mil-Spec phosphate coating gave it a rugged, matte finish, and the medium profile felt substantial without being overly heavy. The chrome-lined bore was clean and smooth, promising longevity and ease of cleaning.
I considered barrels from Ballistic Advantage and Faxon Firearms, both reputable brands in the AR parts market. However, Spikes Tactical won me over with their reputation for rigorous testing and the specific mention of DIN 21CrM0V511 steel, a material known for its strength and resistance to heat. My initial impression was one of excitement; this seemed like a barrel built to last and perform.
Real-World Testing: Putting Spikes Tactical 300 Blackout 16in Medium Profile Rifle Barrel, Stripped to the Test
First Use Experience
My first range trip with the Spikes Tactical 300 Blackout 16in Medium Profile Rifle Barrel, Stripped was focused on zeroing and function testing. I mounted a Sig Sauer Romeo5 red dot and started at 50 yards, using both supersonic and subsonic ammunition. The weather was mild and clear, perfect for dialing in the new build.
The barrel cycled both supersonic and subsonic rounds flawlessly. I experienced no failures to feed or extract, a testament to the correct gas port size and proper chamber dimensions. It took a few adjustments to get the red dot zeroed for both ammo types due to their differing trajectories, but once dialed in, the groupings were promising.
Extended Use & Reliability
After several months of regular use, the Spikes Tactical barrel has proven to be exceptionally reliable. I’ve put hundreds of rounds through it, from plinking at the range to hunting hogs in the Texas brush. It continues to function flawlessly, even after getting dirty and being subjected to less-than-ideal conditions.
The finish has held up remarkably well, with no significant signs of wear despite being bumped and scratched in the field. Cleaning is straightforward; the chrome-lined bore wipes down easily, minimizing the time spent on maintenance. Compared to my experience with other barrels that require meticulous cleaning to maintain accuracy, this Spikes Tactical barrel is a breeze.
