TM M14 Strip down to access hop unit guide
Please use this guide as a helpful tool for when you need to upgrade your rifle. The TM M14 Strip down to access hop unit guide should be used as a guide only and we cannot take any responsibility if you lack the knowledge or tools to carry out the task competently.
Before we start make sure you have the following tools
- Small Philips screwdriver
- Medium Philips screwdriver
- Flat bladed screwdriver
- Allen keys
Lie the rifle down on a flat surface so you don’t loose any items you take off the rifle.
Remove any slings, scopes, silencers and any other attachments to the rifle (stock pads don’t matter)
Pull down on the trigger guard until it hinges and then comes off the stock completely
Now you can slide the top part forward (on some the front has to be unclipped 1st either by undoing a Allen screw and then sliding it forward) and then lift it out of the stock careful not to catch the wiring as you remove it.
Now you can put the stock and trigger guard out of the way as you won’t need them until you re-assemble it. You now need to remove the screw holding the RAS rail on (or if you have a top cover unclip it)
Remove the top rail and put that with the stock out of the way.
Remove the two screws holding the cocking lever stop on, there is a small one next to the hop adjuster and a bigger one near the trigger return spring.
Remove the rail and put to one side.
Lay the rifle on the side so you can access the cocking handle mechanism.
Remove the spring guide by pushing the rod away from the receiver and then tilting it outwards to release it.
Now you can pull down fairly stiffly on the top of the cocking handle (it will act as a lever against the receiver) this will enable it to tilt off the rails.
You can slide the cocking lever out of the holder and remove the fake bolt catch.
Now fully take the hop off with the adjuster and then remove the six screws. Four from the silver barrel clamp and the two either side of the hop adjuster.
The barrel clamp will shoot forward so try to hold it and release it slowly.
Remove the barrel clamp.
Slide the outer barrel off the inner barrel careful not to lift the inner barrel up as you do this.
Now you can lift the hop and barrel assembly up (toward yourself as you look at the picture) and then it should lever out around the adjuster. If it gets stuck be patience it will come.
With re-assembling the rifle it’s basically all in reverse until it comes to the cocking lever refitting, this is where you need to catch the bolt catch and pull it fully to the rear where there is a little indent where you can press hard and it will click back onto the rails. Sometime you need to remove the grub screw holding the cocking lever on as it gets in the way.
PLEASE ONLY ATTEMPT THIS IF YOU’RE CONFIDENT. I HOLD NO RESPONSIBILIES FOR PROBLEMS OR BREAKAGES.
