The redesigned lugs of the Relia-Bolt virtually eliminate the most common MSR malfunction; the bolt to barrel extension jam.
Haven’t cleaned your rifle? Is it out of time?
Relia-Bolt compensates by providing a patented camming action which guides the bolt past obstructions and into battery. (U.S. Patent No. 9,863,729)
The rounded/tapered lugs push past carbon and debris when the square edges of traditional bolts would typically jam.
Once into battery, the rear edges of the lugs fully engage the barrel extension for absolute strength and security.
