Rimfire Actions

.22 Rimfires

These are our line of rimfire actions. They all are designed for the popular 22LR cartridge.

They range in use from competition 22 rimfire benchrest to tactical trainers to hunting.

The 2500XS meets Sporter class IR50/50 rules, but will not feed well from the magazine.

The 2500X line of actions is SPF’s attempt at perfection. No stone was left unturned for this line of actions. The processes and steps that occur in the manufacture of these are bordering on being ridiculous. We start with the finest stress relieved 416R steel. We gundrill, pull ream with barrel type bore reamers and OD turn the blanks to an oversize dimension. At that point some of the machining happens. We then heat treat the parts, stress relieve them and then GRIND the OD to the ID. The threads and face are then put in and engraved. The parts then go to Melonite to surface harden, make slick and black. They are then re-ground again and the OD is held within 0.001 diameter, straightness and roundness. It also gives the attractive black lettering on the perfectly ground surface. All the internal parts are made in similar fashions.

The ignition system is a culmination of all the designs out there with all their issues fixed. No other action completely controls all the angular misalignments and rubbing points like this one does. The firing pin is guided internally in the bolt such that the only contact points are the pin in the front and a small section in the rear near the cocking piece. The bolt shroud is located in the body by a pin that perfectly centers the cocking piece in the trigger such that good consistent contact is made to the trigger sear. The shroud is then located to the front bolt half with a setscrew into a spot to perfectly align the pinholes for the firing pin.

Other features include easy loading, choice of removable bolt knobs, trigger hanger for popular Remington pattern triggers, Wire EDM cut extractors from tool steel and most importantly, tolerances that are hardly measurable. The 2500X and 2500XS are available in RBRP and RBLP configurations. The bolt pattern on the bottom is the same as the Turbo, but the front is slightly longer. The 2500XS uses a Sako magazine. It is very lightweight and aimed SPECIFICALLY FOR THE BENCHREST SPORTER CLASS. Don’t try to really use this as a repeater. Feeding from the magazine causes issues and is not recommended and we will not accept responsibility for anyone using it in this manner.

The 2500XR is a true repeater using low cost Savage magazines. This is aimed at the tactical trainer market or for the customer that wants a true high quality 22 that just isn’t available in America anymore. It shares most of the features of the 2500X line. The OD is not ground on this action and the surface is all black for the tactical market. It fits into a standard short action Remington footprint stock. It works in a standard BDL bottom cut with the door removed. It usually works with most DBM setups also. The magazine system is self contained and does not require any stock attachments etc. The area around the trigger hanger may need relieved to clear the hanger. It works with most triggers, but call us for our list. The triggers like the Timney that pivot from the rear do not work with the bolt design.

Available in RBRP only.

We also supply a full line of scope mounts etc for these. We have them in different offsets and are true Mil Spec Picatinney.
