Add a Breech Safety to a Cheap Chinese Pellet Gun

This is a b3-1 chinese pellet gun, the cheapest pellet gun ever made, and would cut your hand clean off, you've got to ask yourself a question: Do I feel lucky? Well, do ya, punk?

You see, these little gems, fun too shoot thou they are, lack an important safety mechanism that prevents the breech slamming shut and amputating your fingers through accident or mechanical failure.

Let's fix that.

Standard disclaimer There are risks inherent in the modification of any weapon, anyone undertaking to modify a weapon based upon the information in this instructable agrees to hold the author blameless for any injury, accident, or death resulting.

Redneck disclaimer, I ain't not no gunsmith, iffen ya'll dun do this don't be blamin' me iffen sumthin goes awry.

Step 1: Disassembly

Check to make sure the weapon is unloaded, then disassemble by removing the screws on either side at the front of the stock and the two screws holding the trigger guard in place.

Lift the action out of the stock, note that the pins holding the trigger mechanism together are free floating and will FALL OUT, wrap a piece of paper around the trigger mechanism and secure with rubber bands.

Step 2: Yada

cock the weapon and immediately block the breech with a piece of wood and use cable ties to hold in place. Use care as the trigger is now exposed and even with the breech block, discharge will destroy the gun.

Step 3: Drill

Drill a 3/16ths hole through the receiver just in front of the breech face. Slip the action carefully back into the stock and mark where you will need to relieve the stock. Make the stock relief cuts with a rat tail file and touch up the stock finish.

Step 4: Reassemble

reassemble the weapon but when replacing the forward right hand screw attach a "Sliding door security pin" (available Home Depot $2)

Step 5: To Use

Cock the weapon. (A smart observer will note that the weapon was NEVER decocked, bonus point to you)
Insert the pin through the holes drilled into the receiver
Load the weapon
slide the pin out
close the breech
aim
fire
