I received a Bear Creek Arsenal 20 inch stainless 6.5 Grendel complete upper from a very good friend for Christmas this year. I was blown away at his generosity. When it came i looked it over and didn't see anything that was out of place or that looked wrong... that is until I tried to install a Magpul bipod mount on the M-Lok rail that came on the upper. The M-lok openings are so out of spec(undersized) that the t-nuts would not go on. The spec for the openings is 7mm according to Magpul... they are the experts on M-lok as they are the ones that came up with the design. The openings on the handguard measure 6.3mm to 6.75mm... too small to work! If the handguard is this out of spec what else is too?
I contacted BCA on the 27th of December by email to their warranty department letting know that the 15 inch rail was out of spec and unusable. I also talked with a customer service rep on Facebook messenger. The customer service person said that there was nothing they could do and that it had to be handled by email with the warranty department. I have tried calling their number more then a dozen times and no one answers their phone and I get the message that the voice mail box is full. The person on Facebook messenger tells me that there is a new manager over the warranty dept but I still have not heard from them. I do realize that new years day was last week and that were closed, but, does it really take more then a week to reply to an email? Are they they that backed up with customer problems that they can not answer an email?
There are better companies to deal with and I urge you to do so. If you choose to deal with Bear Creek Arsenal do so fully informed that you may get stuck with what they decide to ship to you!
