Toolcraft NIB BCG... SIMPLY THE BEST!! December 12, 2018
Reviewer: Duke King from Bridgeport, OH United States  
LISTEN UP FOLKS! SERIOUSLY! I've submitted only a small handful of reviews in approx 20+ years shopping on the net. This BCG is deserving of a 5 star review. TOOLCRAFT NIB BCG  is worth soooo much more than the price. You'll have to simply trust me, as I've had others to compare it to. ARGUABLY the best on the market. I believe, UNARGUABLY, it to be the best NIB BCG available. Go ahead and purchase one and then tell me I'm wrong...you won't! Construction is ROCK SOLID..impressive! Also, the finish/coating is superior; EXTREMELY SLICK & SMOOTH...I truly think it will last forever, quite possibly. Another thing I need to mention, and strongly advise folks to consider:. Always think about a company's reputation and cust service. This is just as impt as the quality of the product itself. And just FYI, TOOLCRAFT is at the very top...they are simply a first-rate company! Lastly, just a reminder...I rarely ever post a review of any kind in 20 years of online shopping! 'Nuff said. GOD BLESS!

Reviewer: Thomas Lower from Rochelle, IL United States  
I recently purchased a Nickel Boron Bolt Carrier Group for my first AR build. I'm not finished with the build, but Carrier Group arrived safe and sound.
