4r3

4R3 LLC is a small custom finishing shop founded in 2023 and based out of San Tan Valley, Arizona. They focus on two core services: precision stippling for tactical grips and durable Cerakote finishing for firearms and edged weapons.

This is a mail-in operation. You send in your firearm parts (grips, slides) or knives completely disassembled and off the firearm. They return finished work in 1-2 weeks. They don't accept full firearms—only individual components.

• •2011 Grip Stippling covers both Prodigy and Staccato models with three texture options:

• •Shock texture (standard)
• •Crater texture (+$10)
• •Thatch texture (+$20)

You can also add mainspring housing stippling. Options include stippling alone, single-color Cerakote alone, or both services combined.

• •Sig P320 Stippling and Cerakote Service follows the same approach—send in your P320 grip module for custom texturing and color finishing.

They offer 50+ Cerakote colors including:

• •Multicam variants: Dark Grey, Olive, Bright Green, Dark Brown, Dark Green, Light Green, Pale Green
• •Military/Tactical: Coyote Tan, FDE (Magpul and others), OD Green, Sniper Grey, Desert Sage
• •Performance brands: Noveske, Troy, Barret, Springfield, Sig, Glock specs
• •Bold finishes: Zombie Green, Bazooka Pink, Electric Yellow, Cobalt, Gold, Rose Gold
• •Specialty: Multicam Dark Grey, Jesse James Cold War Grey, Stainless, Bright Nickel

Colors run from H-140 (Bright White) through H-900 (Electrical Barrier).

They handle both blade and handle Cerakote work. Send in your knife and they'll finish the blade, handle, or both with your choice of colors.

Firearm slide finishing available for slides sent in separately.

• •Sig P320 Grip Modules ($90)
