TECH TIP: Use a Block to Maintain Front Bag Shape

John Loh Front Rest JJ Industries

front rest bag blockHere’s a simple solution for lumpy front sandbags. Cut a small block the width of your fore-end and place that in the front bag between matches. You can tap it down firmly with a rubber mallet. This will keep the front bag nice and square, without bunching up in the center. That will help your rifle track straight and true. Rick Beginski uses wood (see photo), while our friend John Southwick uses a small block of metal. The metal block might work a little better, but the wood version is easier to make with simple tools. John Loh of JJ Industries offers a slick Delrin block with a built-in bubble level. Loh’s block helps ensure that the actual top surface of your front bag is level, as distinct from the front rest assembly.

Budget Co-Axial Rest — The $200 Caldwell (Plus Upgrade)

fire control rest conversion

Available for under $200.00 including front bag, the Caldwell Fire Control front rest is a remarkable value. It makes the co-axial, joystick design more affordable than ever. We used the Fire Control front rest when testing our Ultimate Varminter 20 Practical AR. Once we removed some sand from the tri-lobe front bag, the rest worked quite well.

Get a Fire Control Rest for $197.99
Precision Reloading is running a sale this week on Caldwell products. Now through May 23rd you can get the Caldwell Fire Control Front Rest for just $197.99. That’s a great deal for guys on a tight budget who want a modern joystick-style front rest. With the conversion described in this article, you can put together a system that works pretty darn well, and is more than adequate for many applications, including prairie-dog hunting (from a bench).

Upgrading Fire Control Front Rest with Sinclair Top

While most Fire Control owners are happy with the product, many have wanted to replace the tri-lobe front bag with a more conventional front bag from Protektor or Edgewood. This isn’t as easy as it looks because the width of the Fire Control top is too narrow for most standard 3″-wide front bags. On a “special order” basis, Protektor has crafted some narrower leather front bags that fit pretty well, but some shooters have decided to “upgrade” the entire front assembly.

Forum member Doug M. (aka DrJeckyl), has come up with an elegant solution that allows a Sinclair Int’l Benchrest Rest Top to be fitted to the Fire Control Rest. Doug notes: “The Caldwell Fire Control is a nice rest for the money, but it comes up short in the rest top department. The Sinclair RT-3 [or its replacement, the Gen II B/R top] fits perfect with minor modifications.” Shown below are the main components:

To adapt the Sinclair RT-3 or Gen II B/R top, Doug merely had to drill a couple holes in the RT-3 baseplate, and adapt a spacer to get the height correct: “The Caldwell factory top has a raised mounting portion so a 1/8″ piece of stock will be needed as a spacer to the flat-bottom RT-3. The spacer needs to be cut to the same length as the movable portion on the rest. And you should plan the mounting accordingly so the left thumbscrew clears the vertical height column at full left position (there is a cutaway in the rest under the thumbscrew that allows for easy access to the screw).” We have labeled the photo with dimensions, but Doug cautions you should measure your own original plate to insure the drill locations are correct for your unit.

The completed installation, with the RT-3 installed on the Fire Control rest is shown at the top of this article. Doug says it works very well. To learn more about this conversion, with Doug’s measurments for the hole-spacing and his specs on the fasteners, go to the original thread in our Shooter’s Forum. NOTE: Sinclair no longer sells the RT-3 top, but Sinclair’s $75.99 Gen II B/R top can be converted just as easily. LINK to Fire Control Rest Top Conversion Forum Thread.
