I received an e-mail from MCarbo about the stainless steel guide rod & recoil spring that I purchased for my 1095 10mm Hi Point carbine.
According to the e-mail the original spring & guide rod actually act as a buffer, and the replacements will cause damage to the breech bolt.
If you installed one of these spring, or guide rods, please re-install the original guide rod & spring. If you no longer have them Hi Point will replace them under warranty.
MCarbo is paying for the return shipping, and is going to refund the money I paid for the parts as well.
