Parts

Shooters usually upgrade a gun for one of four reasons: to see the target and the aiming point faster, to reload without fumbling, to hold the gun more steadily, or to get a lighter, more even trigger. The parts in this section do exactly that. Nearly all of them replace a factory part, fit the gun they are made for without gunsmithing, and can be removed again.

Every part here is made for specific models. Before you look at a part type, it helps to know your exact model and version: whether the slide has a factory optics cut, which generation it is, and which caliber. If you prefer to start from your gun, open By model.

Aiming: sights, red dots and how to mount them

This is the largest group, because it is where most shooters start. New iron sights change how quickly your eye finds the front sight and what you can still see in poor light: fiber optic is bright in daylight, tritium glows in the dark, and an adjustable rear sight lets you bring the hits to where you aim with your own load. See Sights.

A red dot puts a single aiming point on the target, so your eye stays focused on what you are shooting at instead of lining up two sights. How it goes on depends on the slide. A slide with a factory optics cut takes a plate matched to the footprint of your optic: see Optics ready plates. A slide without the cut takes a mount that replaces the rear sight in its dovetail, so nothing needs to be milled: see Red dot mounts. The optics themselves are in Red dot sights. The whole topic is gathered under Aiming.

Grip and reload

In a match, time is lost on reloads and on regaining the grip after each shot. With a magwell, a magazine that arrives slightly off line is still guided into the gun. An aluminium base pad adds capacity and mass: the empty magazine falls out cleanly and the new one seats with a firm push. Textured or 3D grips give the hand a fixed place on the gun, and a frame mount adds weight under the muzzle to keep the sights on target during recoil. All of it is under Grip & reload.

Trigger and internals

A lighter, more even trigger helps you break the shot without moving the gun. Competition springs from Eemann Tech reduce the weight of the trigger, sear and main springs on the CZ 75 family and other models, and recoil springs come in graded weights so the gun cycles reliably with your ammunition. Aluminium triggers, a low profile safety and compensators are in the same group: Trigger & internals.

Rifle and shotgun parts

For AR-15 and AR-9 rifles there are free-float handguards and M-LOK add-ons such as hand stops and grip panels. For semi-automatic shotguns there are adjustable stocks that set length of pull and cheek height, and magazine tube extensions that add shells for longer stages. See Rifle parts.

How to make sure a part fits

Each product lists the models it fits in its title and in a full model list on the product page. Look out for versions that look alike: optics ready and standard slides take different sights, older and newer generations of the same model can differ, and many grip parts come per caliber or frame size. If the title says Optics Ready, OR, MOS or OSP, the part is made for a slide with a factory optics cut.

Frequently asked questions

Can I fit these parts myself?

Most parts replace a factory part with no machining: sights and mounts go into the existing dovetail, plates into the factory optics cut, and magwells, base pads and grips bolt on. Some sight makers, such as LPA, recommend having their sights fitted by a qualified gunsmith. Check the product page for any special tools.

Are these parts allowed in competition?

That depends on your discipline and division. Base pad length, magwell size and red dots are limited in some IPSC and IDPA divisions. Read the current rulebook of your division before ordering.

How fast do you ship?

Orders placed by 8 AM CET are dispatched the same business day; later orders leave the next business day. We ship from Jaroměř in the Czech Republic.

Can I return a part that does not fit?

Yes. You can return an unused part within 14 days of delivery. Write to info@ubitzu.eu first, then send it back within 14 days of that message.
