The Harris BRM-S series of bipods is one of the most popular choices for precision rifle shooters. The swivel base, spring actuated legs and fast deployment make it well suited for fast setup on uneven terrain. The BRM-S has served military and law enforcement shooters all over the world and is made here in the USA.
Harris bipods are good, but one glaring deficiency is the way they attach to the rifle. Harris Bipods are designed to attach to the sling swivel of a standard rifle stock. This works well if your rifle is equipped with a single or pair of swivels. If your rifle is a more modern design with picatinny rails, then you run into a problem. Harris does not offer a rail attachable version of their bipod. If you want to attach a BRM-S or other Harris Bipod to your rail equipped rifle you need to resort to a selection of adapters. Some work well. Some work poorly. All will add some height to the bipod in both it’s extended and stowed position. Finally, all of the adapters still attach through a single stud. That is a lot of leverage on a very thin piece of metal. If you properly load a bipod while shooting, then every shot applies forward and back force to that small point. Alamo Four Star has a solution.
Alamo Four Star, creators of the DLOC mount offer a DLOC conversion for the Harris swivel bipods. The DLOC-S kit replaces everything above the hinge with a strong and solid rail clamp. The kit includes a DLOC-S mount, Shooters Adjustable Rotary Grip (S.A.R.G.) Knob, stainless wear washer and replacement 1/4″ aircraft nut.
Installing the DLOC-S and S.A.R.G. is quick and totally changes the utility of the Harris Bipod. With the DLOC-S mount you can rapidly remove your bipod from one rifle and install it on another rail equipped rifle without any adjustment. The DLOC mount automatically adjusts for minor variances in the rail dimensions.
The S.A.R.G. knob adds a new feature to the Harris bipod. After installation it gives the shooter the ability to quickly lock out the swivel feature on the bipod. It is large enough to grasp with slick or gloved hands, but low profile enough to be out of the way. You no longer need to concern yourself with “clocking” a lever to keep from breaking it on a barricade.
Installation of the DLOC-S is simple. The only tools needed are a 1/4″ socket or nut-driver.
Note: If you do not already have a bipod, Alamo Four Star sells the Harris BRM-S with the DLOC-S and S.A.R.G. already installed (Link).
3. Be careful not to loose the the pin from the back of the hinge assembly.
9. While holding the bolt and cross-pin in place, set the stainless wear washer over the threaded end of the bolt.
The installation is now complete. Enjoy your new bipod.
