I was one of the guys who had an issue with a lower. After a phone conversation with Josh he told me that he would replace the lower (or reimburse me for any repair charges) if the problem could not be resolved. He suggested for me to bring it to Brent and Gabe and have them look at it. Gabe made an observation that the pmags I have were pushing the bullet into the center of the ramp causing a jam. He milled a bit of material for me and all seems good. I dont know why that particular lower has issues with certain mags but hopefully the problem has been remedied. I haven't had a chance to fire it with the new mod but I have cycled it by hand as slow as possible and have not had any hang ups. I'm going to fire it again and hopefully put 1000 more rounds through it.
I am confident that if there are any more problems, Josh at Protective Bunkers will make it right. He stands by his products. He has earned a customer for life.
I plan on buying one of their new cnc'd lowers in the near future.
Buy with confidence!
