I ordered this in order to have a spare or two around, just in case. Machining and materials look good so far. Everything I have ordered from Thunder Tactical has been good quality.
Absolutely superb and the service was equally excellent . Retired K9 Handler Clint B. / Al.
I purchased a melonited (Nitrided) BCG from Thunder Tactical to complement my Bear Creek Arsenal 16" Mlok 300 AAC Blackout upper assembly. The melonite finish made cleaning a hassle-free task, and the BCG performed flawlessly during my range session. I was impressed by Thunder Tactical's quick delivery, with the package arriving at my doorstep in just three days. Their efficient service and quality product made for a satisfying experience.
