Sylvan Arms Custom Red Dot Optic Slide Kit - Trijicon RMR Footprint Cut, Fits Glock 19 Gen 3 - Completed Internal Parts Components, RMR Cover Plate & Alignment Pins - Black DLC Finish - GL19G3Pk
Product Description
Upgrading a baseline factory handgun, constructing a high-performance polymer frame build, or staging a defensive concealed-carry system for faster low-light indexing reveals an immediate mechanical bottleneck: heavy, non-milled factory slides. Traditional solid iron sights require perfect three-point visual alignment, slowing down your focus loops under sudden threat conditions. Sending your standard slide out to a machine shop for custom milling leaves your frame completely stranded without functional utility for weeks on end. The **Sylvan Arms™ Custom Glock 19 Gen 3 RMR Cut Slide Assembly Kit (GL19G3Pk)** completely shatters these build delays. Operating as a comprehensive, out-of-the-box armorer package, this custom slide comes pre-milled and bundled with a full set of pre-fit internal components, turning your staging bench project into a reflex-ready tracking machine.
Precision CNC-machined in the United States from a solid block of certified, domestic **17-4 PH stainless steel billet**, the structural chassis of this custom slide maximizes geometric rigidity and unyielding core longevity. The exterior surfaces are treated with a premium, low-friction **Diamond-Like Carbon (DLC) matte black finish shield**. This advanced state-of-the-art physical vapor deposition (PVD) hardcoat exhibits exceptional surface hardness that actively repels trail moisture, carbon scoring, and abrasive holster friction. The slide layout incorporates aggressive **front and rear directional cocking serrations** and weight-reducing window cutouts. These windows lessen kinetic reciprocating mass, flatlining muzzle rise while maintaining a flat, predictable tracking loop during rapid firing strings.
In high-stakes competitive dynamic match courses, intensive defense frames, or tactical range staging blocks, the precise optical interface of the **811313033452** platform yields a massive tactical advantage. The optics pocket features an exact, factory-milled **Trijicon RMR footprint cut**, seating your miniature reflex red dot exceptionally low to the bore axis. The comprehensive kit includes an integrated **billet RMR cover adapter plate**, matching plate screws, and dedicated **RMR indexing locating pins** to eliminate cross-axis shear stress under rapid cycling forces. Pre-loaded with a completed internal parts sub-assembly—including a matching firing pin, high-strength extractor, spring-loaded bearing, and dual-coil safety block components—this kit transforms your workbench build into a solid-state tactical asset.
*Armorer Bench Notes & Technical Field Assembly Guidance: The Sylvan Arms GL19G3Pk custom kit arrives from the factory with a completed slide body hosting pre-installed internal slide parts, an optic cover plate with mounting fasteners, and RMR alignment pins on your workbench. CRITICAL FRAME COMPATIBILITY & FIRING PIN CHANNEL LINER NOTE: This custom assembly is engineered strictly to match **Glock 19 Generation 3 factory frames** and exact mil-spec dimension aftermarket polymer lower assemblies (such as the Polymer80 PF940C or SCT Manufacturing frames). It will *not* fit Gen 4 or Gen 5 lower frames due to wider nose-ring dimensions. **Armorer Workbench Installation Sequence:** While slide internals are pre-assembled, armorers must install their own barrel and recoil guide rod assembly (sold separately). Before bolting down your Trijicon RMR or Holosun 507C reflex sight, ensure the slide's top optic threads are completely free of manufacturing oil. Set the RMR locating pins inside the milled slide pockets, lay your red dot flat, apply a minimal drop of medium-strength removable blue threadlocker to the plate screws, and torque them incrementally to exactly **12–15 in-lbs**. **Pro-Tip Safety Guidance:** Never over-torque past 15 in-lbs, as excess fastener depth on the right-hand optic thread hole can physically pinch the underlying extractor spring-loaded bearing rod, jamming your extraction mechanism and inducing immediate stove-pipe cycling failures downrange.*
Key Features
- Complete Internal Components Kit: Ships factory-packaged with all firing pin, safety block, and extractor parts pre-assembled, saving armorers separate small-part component costs.
- Factory Milled Trijicon RMR Cut: Precision-milled optic pocket natively hosts elite Trijicon RMR, SRO, and matching Holosun micro reflex sights low to the slide's bore center.
- Diamond-Like Carbon (DLC) Coating: Encased in an ultra-hard matte black DLC finish jacket that dramatically reduces mechanical sliding friction while completely blocking finish wear.
- Monolithic 17-4 Stainless Steel Build: CNC-machined from a solid block of high-tensile 17-4 PH stainless steel billet to prevent warping, fracturing, or thread stripping under extreme use.
- Weight-Optimized Side Windows: Features strategic structural window cuts that lighten the reciprocating slide assembly to hasten cyclic balance and smooth out felt recoil.
- RMR Alignment Pins & Cover Plate: Arrives bundled with dedicated structural locating pins to absorb heavy recoil shear forces, alongside an elegant flush-fit adapter cover plate.
