Description
Sinclair built this rest for anyone who wants the precision of a benchrest setup without lugging a cast iron anchor across the range. The whole tripod is machined from aluminum right here in the USA, which drops the total weight to right around 5.65 pounds. That is a savings of over 11 pounds compared to Sinclair's standard cast iron rests, and you feel it the moment you pick it up and carry it out to a distant firing line.
What the RT-3 Top Brings to the Bench
The RT-3 is Sinclair's windage rest top, and it is where a lot of the accuracy magic happens. It gives you fully lateral windage movement with a generous 46 inches of adjustment at 100 yards, or about 23 inches at 50, so you can walk from your sighter to the record bull with a quick turn of the knob and never break your position. Each top is tested at the factory with 17 pounds of forend weight, so it holds up under real recoil. The non-marring surface cradles your stock securely and keeps wood, laminate, or synthetic finishes free of wear marks.
Setting Up the Sinclair Lightweight Rest
The RT-3 top mounts on a standard Sinclair rest post and accepts owl-ear style Protektor and Edgewood front bags in sporter, varmint, and benchrest sizes. Keep in mind the front bag is sold separately, so you can match the ears to your forend width. Lightened leg screws and a T-handle round out the package and make setup and breakdown quick.
This one earns its keep across a lot of disciplines. It is a favorite for F-Class thanks to the base accepting extended leg screws, and it shines during load development, rimfire benchrest, sight-in sessions before a hunt, or just plinking on a lazy afternoon. If you want competition-grade rigidity that you can carry with one hand, this is a hard setup to beat.

Frequently Asked Questions
Does the Sinclair Lightweight Benchrest Rest come with a front bag?
No, the front bag is sold separately so you can match it to your rifle. The RT-3 top accepts owl-ear style Protektor and Edgewood front bags in sporter, varmint, and benchrest sizes. A number 1 bag suits most hunting rifles, while a number 2 or 3 works better for varmint, AR, and F-Class setups.
How much lighter is this rest than a standard cast iron rest?
The machined aluminum tripod, lightened leg screws, and T-handle bring the whole package down to about 5.65 pounds. That is a savings of over 11 pounds compared to Sinclair's standard cast iron rests. If you walk to distant firing lines or move gear between stages, that difference adds up fast.
Is the RT-3 top good for F-Class and long-range bench work?
Yes. The RT-3 windage top gives you 46 inches of lateral adjustment at 100 yards, which is plenty to walk from your sighter to the record bull without disturbing your position. The tripod base also accepts F-Class extended leg screws for the added height those shooters want.
Will this rest scratch or mark my rifle stock?
The RT-3 top uses a non-marring surface designed to cradle the firearm without harming wood, laminate, or synthetic finishes. Paired with a properly filled front bag, your forend rides on the bag material rather than any hard surface. It is built to protect your rifle while still giving you a rigid, repeatable lockup.
