OLD AIR RIFLE

[aadhaulya]

I have two old Air Rifles. I do not know the make or model of the guns. There are no no markings on them either. I have two questions' 1. I want to add a muzzle weight on the older one. Can I make one if yes what should be the weight of that thing. 2. I have some sort of muzzle weight on the other one, I has a lots of evenly placed holes on the weight. What is the purpose of these holes??

Hi aadhaulya,
Muzzle weight is left up to you. Just remember the balance of the gun should not be lost and the tolerance between muzzle weight and barrel should not be more than one mm. The rifle should be evenly balanced in you forearm in the artillery hold position.
To the second question, the muzzle with holes is just cosmetic. Lot of Indian guns sport this. A few pics would be nice.

Atul,
1. The approximate weight of the muzzle brake could be anywhere between 120 gms to 150 gms....although there is no specific formula for arriving at an ideal weight. The purpose of a muzzle brake are:
a) Provides leverage for cocking the AR with ease
b) Protects the crown of the AR's barrel from damage
c) Balances the barrel's harmonics when the AR is discharged
2. The holes in the muzzle brake are provided to enable the pellet to exit through less 'turbulence' of air so that the pellet does not pitch or yaw in the initial stages of its flight.

Thanks BD and Briha ji,

Would it be possible to replace the spring with a nitro piston??

No not possible in old ARs since.....
The piston & trigger assembly have to be re-configured to accommodate the nitro piston....
It's not an easy task......
