Just ordered one. They have excellent reviews.
They might be the greatest thing since sliced bread, but 90-95 percent of the site reviews speak to fast shipping and only a few have actually installed them in their ARs.
Does anyone have first-hand experience with the performance of this BCG? Any reports on durability at 750-1000 rounds?
Fast shipping is great, but how about some actual user data points?
Ordered one too. BCGs appear to be the only thing they produce - you would hope they know what they're doing! Free shipping and lifetime warranty. Good reviews on their website.
Very fast delivery. Finish is beautiful! Looks to be very well made. Have not tested operation yet.
