Our Select Fire Customers have stated carrier bounce has been eliminated due to the polymer base buffer. We have run select fire and have not experienced carrier bounce since the introduction of the integrated polymer base buffer. Patented buffer technology has been in use for 7 years with over 15,000 rounds without needing to replace the polymer buffer ; however, if one damages the polymer buffer it is easily replaced.
Important Note: Some off-the-shelf rifle cleaning solutions such as Hoppes #9 can react negatively with NiB finishes. Since our carriers have nickel-based coating these should not be used on NiB/EXO coated products. Always refer to the manufacturer's recommendations before use on NiB/EXO coated products.
