Riflespeed RS Gas Block Replacement Plunger #917

Riflespeed RS Gas Block Replacement Plunger #917. Plunger service life varies from 10000 to 25000 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. You can also select shorter or longer plungers to fine tune the range of adjustments used for your specific firearm. This is generally not something that's necessary but does provide a tremendous amount of flexibility thanks to the modular design of the RIFLESPEED line of Gas Controls. 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 upper 80s. 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. So what's the purpose of doing this? 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. 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 insure that you can reduce gas when summer heat arrives. Again this process is not a necessary step as the plunger provided with your Gas Control has been selected for general-purpose use in most configurations but the ability to easily fine tune the system is one of many benefits of the modular design of RIFLESPEED Gas Controls. Plunger numbers correspond to the length of each Plunger for ease of selection.
