Enhance your shooting experience with RS Replacement Plungers!
If you like to keep spare parts on hand for maintenance or replacement, add the appropriate size Plunger to your kit. Plunger service life varies from 10,000 to 25,000 rounds, depending on your firing schedule. When you replace a worn-out barrel or bolt or when the working end of your Plunger has been worn away by half, then it's time for a new plunger.
Customisation for Your Firearm
You can also select shorter or longer plungers to fine-tune the range of adjustments used for your specific firearm. This provides a tremendous amount of flexibility thanks to the modular design of the RIFLESPEED™ line of Gas Controls.
Example of Adjustments
For example, you've completed the setup instructions found on riflespeed.com and determined that with Plunger 937 installed, your carbine uses setting number 1-6 for suppressed fire with milspec ammo and setting number 1-11 for unsuppressed fire with commercial .223 ammo. You determined these settings on your local range during the early summer when temperatures were in the mid-80s.
Adapting to Conditions
Since more gas will be required during extreme cold winter temperatures, you can select a shorter plunger like Plunger 917 to shift the position of your ideal settings to the lower portion of the adjustment range. Since every plunger number represents a shift of 2 positions on your control knob, instead of using settings number 1-6 and 1-11, you'll now be using settings number 1-2 and 1-7 for suppressed and unsuppressed fire, respectively.
Why Adjust?
Shifting the range of adjustments to lower numbers allows you to have more room to increase gas later when temperatures drop without having to dial past the Rotation Stop to use Rotation Range Two. Since cold guns need more pressure to run and cold ammo produces less pressure, it's important to be able to increase gas flow when temperatures plummet.
Optimal Performance
Selecting the specific plunger that puts your preferred settings in the lower third of the adjustment range gives you the most potential adjustment range. The opposite holds true if you've determined your firearm's settings during cold conditions. You may want to select a longer plunger to ensure that you can reduce gas when summer heat arrives.
Included Plungers
