Asked by: George Munoz - 8/12/2023

A: Yes it will drop right in. It will fit any mil-spec 5.56. Standard Size Integrated Polymer Buffer:
Eliminates metal on metal contact
Eliminates contact between the hardened steel carrier, aluminum receiver extension and buffer
Eliminates hardened steel carrier as it transitions between upper and lower receivers
Self-lubricating, shock absorbing and has seven times the abrasion resistance of carbon steel
Reduction in felt recoil and vibration

Bolt Carrier due to the polymer buffer is not compatible with folding stocks.
JP Silent Capture Spring is not compatible with our bolt carriers. In order to use JP Silent Capture Spring, end-user would need to make modifications to the carrier's integrated buffer.
Armaspec Stealth Recoil Spring is not compatible with our bolt carriers.
Some off-the-shelf rifle cleaning solutions such as Hoppe's #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.
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.
