CVA APEX 1x and 2x Oversize Hinge Pins
Bellm Custom Accuracy Oversized Hinge Pins for CVA APEX and Optima Elite remove the shake and rattle at the hinge area, improve accuracy, and give the precision fit you find in the world's most expensive high grade guns.
Any looseness at the hinge pin results in less than optimum accuracy. Tighten up the fit at the hinge pin, and accuracy nearly always improves.
A snug fit at the hinge is essential to best accuracy.
A barrel that shakes and rattles cannot be expected to place shots in the same place each time. You would not accept a bolt action rifle with a loose barrel, so why be expected to settle for a loose barrel on a break open gun?
Our customers have had great success with our Oversize Hinge Pins for nearly 25 years, starting with the Contender, followed by the Encore/Pro Hunter, and now the same principle is being applied to the CVA Apex rifle.
We have had literally thousands of reports of improved accuracy from the precise fit these pins provide at the hinge with all barrels.
Muzzle loader barrels? I have been particularly impressed with the results from muzzle loader barrels, even though muzzle loader barrels do not subject the gun to anything near the stress the cartridge barrels do.
Are you willing to accept a loose barrel fit? There are tens of thousands of shooters using our oversize hinge pins that would strongly disagree with the under size hinge pins and loose hinge fit coming from the factories.
There are now 2 sizes of APEX pins so that if one size is not quite large enough, you go to the next larger size. Start with the 1x size. If the 1x size is not large enough, move up to the 2x size.
The 1x and 2x sizes will cover probably close to 90% of barrel and frame hole combinations for a nice, precise fit. While the 1x pin covers the vast majority of needs, it also serves as an economical "gauge pin" to determine if you need a larger pin. Buying and learning how to accurately use small hole guages and micrometers is much, much more expensive!
Simply install factory pin first with a GOOD QUALITY heavy oil to lubricate the holes and prevent galling when you tap in the oversize pin. The factory pin serves as a guide pin to keep all three holes aligned while you tap in the oversize pin.
Some degree of force is necessary since you are upgrading the fit from what is known as a "slip fit" to an "interference fit".
A small steel hammer is fine, though some prefer to use a soft face hammer such as made from brass. I only use a small jewelers type steel hammer, myself. If it takes more force than this, then reaming may be necessary for one or two holes.
Based on our many years of experience with oversize hinge pins, you should notice an immediate difference in fit, feel, and accuracy.
In stock and ready to ship!
Note: The stock Optima Elite pin is 1mm shorter than the Apex. In order to work on the Optima Elite, be sure to center the pin.
