I request guidance on how to fix a scope rail on the cylindrical chamber of a side levered .22 spring rifle. Can it be fixed with araldite or similar substance? Will it harm the metal ? I dont actually wish to drill holes into the chamber. kindly guide.
Hi Ganguly,
I hope this helps...
First things first...even a small wrong angle of the rail placement could mess the accuracy completely, so please pay attention. But don't be discouraged...its an easy process if you are careful.
Firstly, sight your rifle at 10 meters.
Then tie a thread from the front sight to the back through the V notch at the back site. This will give you a straight line of vision.
Next, place the rail on top of the rifle under the thread such that the thread passes over the centre of all the holes in the rail.
This will align the rail perfectly.
Carefully use a marker / pencil to mark the rail holes on the AR.
I would advice you to screw the rail to the AR.
You will have to drill the AR to screw the rail. This requires the precise drill bit. I would advice you to seek the help of a lathe operator / fabricator. Its a
very very simple process for them.
Use short screws or screws supplied with the rail. This will not damage your AR.
Apply araldite to the bottom of the rail and screws, and screw them tight. Allow to set.
Remember only the front 15% to 20% approx is the compression chamber, the remaining 80% to 85% is the spring chamber.
It is the compression chamber that should not be drilled.
You can remove the stock and have a look underneath to get an idea.
A few pointers...
1) Fix the rail as far back, about 1/2 inch in front of the power plant cap (the screw-on-cap at the back).
2) Some rails have a forward and backward position. Make sure you know which side should face froward.
I hope this helpes....all the best ! ! !
