Good for the price but bad customer service - Armaspec C Sound Mitigation Gen3 Buffer

This is the 6th SMB I’ve purchased, I’ve never had a problem with anything from ARMASPEC but this one wouldn’t work properly. Upon further inspection the main spring wouldn’t recess completely into the buffer weight causing the BCG to not go fully back thus not letting it chamber another round! I tried to call ARMASPEC they have no phone number listed on their website, (huge red flag) even though they boast a lifetime warranty! It’s always easier to call a company and get problems taken care of immediately and have a new piece shipped out that day, versus sending an email then waiting a day for a response only to send the response and wait another day to get a response and go back and forth like that. I sent them an email waited 2 days have heard nothing, sent another email and got a response that said “what is your home address” which I replied to and have heard nothing again it’s been well over a week! Guess I’ll cut my loses! Their products have always arrived in excellent quality! Guess this time I got a lemon. I’ve had way more good experiences than bad and would buy from them atleast once more!
