Parts of the Firearm

modelr15r25_12_12-WARNING.pngWARNING: THIS FIREARM COULD CHAMBER A ROUND if it is dropped or jarred with a loaded magazine in place - either with the Bolt Carrier Assembly locked to the rear, or in its forward position.


Be sure Cam Pin is installed in the Bolt Group. If it isn't, your rifle can still fire and may explode.

  • If your rifle stops firing with a live round in the chamber of a hot barrel (a misfire), REMOVE THE CHAMBERED ROUND IMMEDIATELY! However, if you are unable to remove the round within 10 seconds, remove the magazine and wait 15 minutes with the Rifle Pointing in a SAFE DIRECTION! This way no one will be hurt by a possible round "cooking-off" (i.e. the round detonating just from the heat of the barrel).  In any event, keep your face away from the ejection port while clearing a hot chamber.
  • Whenever you are handling the rifle or clearing a chambered round, control the direction of the muzzle and keep yourself clear of the Muzzle!
  • If there is water in the barrel, do not fire the rifle. IT COULD EXPLODE!
  • If you hear a noticeable difference in sound or recoil is experienced, STOP FIRING! Either condition could indicate an incomplete powder burn and/or a bullet stuck in the bore.

Important Parts of the Firearm

Congratulations on your choice of a Remington® R-15 VTR or Remington® R-25 Modular Repeating Rifle. With proper care and if used in accordance with the Ten Commandments of Firearm's Safety and this Owner's Manual, your rifle should give you many years of dependable use and enjoyment. The following picture depicts the main parts of your rifle and will aid in understanding the instructions in the Owner's Manual.


This Owner's Manual covers only the Remington R-15 VTR and Remington R-25 Modular Repeating rifles. These firearms are lightweight, gas operated, air-cooled, magazine-fed rifles that are Semi-Automatic in operating mode (i.e., a single round will fire each time the trigger is pulled).

  • On all models, the Upper and Lower Receivers are easily opened for cleaning and inspection. R-15 Models have forged aluminum Upper and Lower Receivers, R-25 Models have extruded aluminum Upper Receivers and milled aluminum Lower Receivers.
  • R-15 VTR Barrels are either Chrome Moly Vanadium Steel or 416 Stainless Steel. R-25 Barrels are 4140 Chrome-Moly Steel. The Bolt Group locks into the Barrel Extension with 7 locking lugs.
  • R-15 VTR and R-25 rifles can be configured with either 6-position Telescoping Buttstocks or Fixed Buttstocks. Forends are free-float tubes machined from aluminum alloy. Magazine capacity is 5 rounds standard, but all AR-15/M-16 Type magazines of capacities from 5 to 40 rounds will fit the R-15 VTR and function in it. The R-25 has a standard magazine capacity of 5 rounds, but 10 and 20 round magazines are available.
