Remove the cap from the end of the tube and be careful of the spring which is under pressure. The plug will come out with the cap.
grip with hand and turn left(counterclockwise) Unscrew it
Remove the magazine cap and forearm, then remove the barrel and mag tube. At the end of the tube will be a metal cap that you can carefully pry out with a screwdriver, some press in and turn to remove them. Use caution, it is under spring pressure.
Unscrew the magazine tube cap, pull the barrel off to the front, remove the forestock. If in doubt, consult the owner's manual. A replacement owners manual is available through Remington's web page.
To remove the plug on a Remington 870 series all you need to do is unscrew the cap on the end of the magazine tube. Carefully because it holds in the magazine spring. the plug is the rod that is inserted in the spring so it cannot compress fully to limit capacity so just take it out and screw the cap back on (the cap compresses the spring) and voila. takes about twenty seconds.
no, the threading is different
Remove left handle grip end cap. The valve stem to fill front air shocks is hidden in the handle bar.
the "end" cap
Probably the maker's initial
I usually have to use a large pair of channel locks to get it loose. The key operative word is GENTLY apply enough pressure to grip but not too much to risk breaking the cap. I have a 91 Wrangler & this works for me.
It all depends on the model. But most new pistols load by removing the cover on the grip. You place the C02 cylinder nose up the the opening. Then thumb screw the cylinder in place so it is just snug. finish by putting the grip back on and tighten the bottom screw all the way in. Some of the older models have a removable cap under the barrel. Remove the cap place the new cylinder inside, and screw the cap back on.
Take the plug out of the mag. unscrew the cap, pop out the spring stopper with a screwdriver. remove the spring and plug. Put the spring back in without the plug.
