The Paddle .308 Oversize Bolt Catch Assembly swaps out that stubby little mil-spec release for something you can actually find fast under pressure. Built by Luth-AR specifically for the DPMS-pattern .308 AR-10 platform, this catch trades the tiny stock paddle for a wide, oval shaped surface that's easy to hit even when you're moving quickly or running gloves. Since this is the full assembly version, it comes with everything needed to make the swap in one shot rather than sourcing small parts separately.
Standard AR-10 bolt catches are small and easy to miss, especially mid-string or with cold hands. Luth-AR reshaped the release into a broader, textured paddle that gives your thumb a much bigger target, so locking the bolt back or dropping it forward becomes second nature instead of something you have to hunt for. That extra surface area matters most when seconds count, whether you're running a stage at a match, clearing a malfunction, or working the gun in gloves during a cold morning hunt.
This bolt catch is machined from 8620 steel and heat treated for durability under repeated cycling, then finished in a black phosphate coating that resists wear and corrosion. It's sized specifically for .308 Win/7.62 NATO builds that follow the common DPMS/mil-spec pattern, so it's meant to drop into most LR-308 style lowers without extra fitting work. Because this is the LR-BC308A assembly, you're getting the catch, spring, buffer, and retention screw together instead of piecing those small parts together on your own.
Swapping this in follows the same basic process as replacing any AR-10 bolt catch, though .308 pattern lowers use a shoulder screw for retention rather than the roll pin found on AR-15 builds. A punch set and a small hex wrench are typically all you need to pull the factory catch and seat this one in its place. If you're working on a less common .308 lower, it's worth double checking catch dimensions against your receiver before ordering, since AR-10 pattern parts aren't as universally interchangeable as AR-15 components.
The assembly version, LR-BC308A, includes the oversized paddle catch plus the spring, buffer, and screw needed to install it. The catch-only version leaves you sourcing those small parts on your own, so the assembly is the easier route if you're doing a full swap.
It's built for .308 Win/7.62 NATO rifles that follow the DPMS/mil-spec pattern lower, which covers a large share of AR-10 builds on the market. Since AR-10 pattern parts vary more between manufacturers than AR-15 parts do, it's a good idea to check your lower's catch dimensions against this part before ordering.
No specialty tools required, just a basic punch set and a small hex wrench, similar to what you'd use on any AR-10 bolt catch replacement. Keep in mind .308 pattern lowers use a shoulder screw for retention instead of the roll pin used on AR-15 builds.
The catch is machined from 8620 steel and heat treated before getting a black phosphate finish, which holds up well against wear and corrosion over repeated use. It's built to handle the kind of high round counts you'd see in competition or regular range time.
