C&H Precision FN509509TST – Superb Red Dot Mount

Description

The C&H Precision FN509509TST is a red dot mount from C&H Precision (model FN 509/510/F 545) with a Holosun 509T Footprint interface.

C&H Precision FN509509TST Overview

A red dot mount raises and secures a reflex or micro red dot on a rail, setting the dot at the height that matches your stock and shooting style. The right height is what makes the dot appear naturally when you shoulder the rifle.

Absolute and lower-third heights are the two common choices: absolute puts the dot level with iron sights, while lower third places the irons in the bottom of the window for a cleaner view.

Fit and Compatibility

Mount type: Holosun 509T Footprint. Height: 1.10″. Confirm the exact firearm model, receiver or slide cut, and the optic you plan to run before ordering, because mounting parts are made to precise dimensions and a near miss does not fit.

Installation Tips

Degrease the screws and mating surfaces, then snug the fasteners in an even, alternating pattern. Use a torque wrench and follow the maker’s inch-pound values; overtightening can crush a scope tube or strip threads, while undertightening lets the optic walk under recoil. A drop of thread locker on base screws, but not ring cap screws unless the maker says so, keeps everything in place.

Build and Materials

It is made from steel and finished in black, with a listed weight of 0.10 lbs and a length of 2″. Machined aluminum and steel parts hold tolerances well, while polymer parts save weight and resist corrosion.

Holding Zero

The real test of any mount is return to zero: the optic should come off and go back on, or ride through hundreds of rounds, without the point of impact wandering. Rigid materials, precise machining and correct torque all contribute. Witness marks with a paint pen make it easy to spot movement at a glance.

Honest Limitations

No single mounting part fits every firearm and optic. Height, eye relief, footprint and rail spacing all vary, and a part that is perfect for one setup can be wrong for another. Budget mounts can work well on rimfires and light recoiling rifles, but heavy recoil and duty use reward premium machining.

Care and Storage

Wipe off dirt and moisture after a wet hunt with a microfiber cloth, keep a small set of the correct bits or wrenches in your range bag, and check fasteners at the start of each season. A light coat of oil on steel parts prevents rust, while anodized aluminum only needs to be kept clean. Protect the optic from dust and rain when the rifle is stored or cased.

Before You Buy

Match the part to your exact firearm and optic, check the height and size listed above, and contact us with the model of your rifle, pistol or scope if you are unsure. Mounting parts and optic accessories are not firearms and ship without an FFL transfer.
