If you are looking for a versatile rest top that is easily adjusted for nearly any forend width (up to 3-1/2") this is the top you need. Our All-Purpose (A/P) rest top features quick adjust levers on the bag squeezing side plates to shorten the time needed to switch from rifle to rifle. The dual-sided sandbag (included - not filled) is reversible from leather to Cordura for use with wood or fiberglass/synthetic stocked rifles. The forend stop can be positioned to accommodate both fore/aft and left/right stock contact. For an upgrade to even more adjustability, it can be easily replaced with our Competition Forend Stop (#749-101-026). Includes a 1/4"-20 screw to mount to our Sinclair rest posts or any other rest post with 1/4"-20 mounting threads.
