If you have wrestled with a stubborn takedown pin on a .308 build, this kit from CMMG is a small upgrade that pays off every time you break the rifle down. The pins are made slightly longer than a standard set, which gives you more to grab and push against so takedown and reassembly go faster with less fuss. Each pin end carries a divot machined into it, so you can seat a bullet tip against it and push without the tool skating off. The whole set wears a matte black finish and is built to tight tolerances, which is exactly what you want out of hardware that gets handled every range trip.
These pins are designed around CMMG's own MK3 platform, which is based on the DPMS high-pattern LR308 family. That makes them a natural fit for MK3 lowers and similar-pattern AR-10 and .308 receivers. Because not every .308 lower is cut the same, it is worth confirming your receiver follows the LR308 pattern before you order. If you are running a CMMG lower or a compatible clone, these drop right in.
This is more than just two loose pins. The kit includes the front pivot pin, the rear takedown pin, and the pair of detent springs that keep everything under tension inside the receiver. That means you have the pieces on hand to finish a lower build or replace a set that has gotten loose or lost over time.
Small parts like these have a habit of launching across the shop during a build, so keeping a set in your armorer's box is never a bad call. Whether you are completing a fresh LR308 lower or refreshing an older rifle, these HD pins give you a cleaner, quicker takedown and the confidence that the hardware is holding up. It is the kind of low-key upgrade you appreciate most when you are field stripping in a hurry.
These pins are made for CMMG's MK3 platform, which is based on the DPMS high-pattern LR308. They also fit similar-pattern AR-10 and .308 lower receivers built to that spec. Since not all .308 lowers are cut identically, it is smart to confirm your receiver follows the LR308 pattern before installing.
They run slightly longer than a standard set, which gives you more surface to grip and push against for faster takedown and reassembly. Each pin end also has a machined divot so you can seat a bullet tip against it and push without the tip slipping off. It is a small change that noticeably speeds up field stripping.
The kit includes the pivot pin, the takedown pin, and the pair of detent springs that hold everything under tension inside the receiver. That gives you the hardware to complete a lower build or replace a worn set. Keep in mind small parts like these are easy to lose during a build, so working over a clean surface or inside a clear bag helps.
Yes, they are a common choice for completing an LR308 or MK3 lower and also make a solid spare to keep on the bench. The longer, dimpled design makes them easier to install and remove than plain pins. Pair them with a full lower parts kit if you are building from a stripped receiver.
