GBRS GROUP 2.91 FTC MAGNIFIER MOUNT

greg@tier-1.co.za — Wed, 26 Feb 2025 15:36:08 +0000

DESCRIPTION:

GBRS Group 2.91 FTC Magnifier Mount

Utilizing UNITY Tactical’s revolutionary Flip-to-Center technology, the 2.91 FTC (Flip-to-Center) brings any magnifier to the 2.91 height to pair with the GBRS Group Hydra Mounting Systems. The 2.91 FTC Mount employs a simple force-to-overcome mechanism and stows the magnifier below the optical sight plane and completely within the footprint of the weapon’s receiver when not in use. This eliminates the flip-to-side placement of legacy products, in which users receive all the benefits of magnification when required with no occlusion of sight pictures when stowed.

GrayGuns – HK P30, P2000 Short Reset System

greg@tier-1.co.za — Thu, 14 Nov 2024 12:09:31 +0000

Description

In a convenient, easy-to-install kit, the HK P30 and P2000 Short Reset System replicates the short reset conversion for HK pistols in our custom action work.

The control latch is precisely wire cut EDM from ground bar stock to exacting tolerances. It is correctly heat treated and coated in a durable nickel PTFE finish for a lifetime of durability and smooth function.

Engineered to provide several benefits:

Shortens trigger reset travel distance by approximately 33 percent
Converts the action to drive the sear directly off the control latch – instead of transferring energy through the catch – for a direct drive connection between the control latch and sear
Reduced trigger over travel values
Maintains all factory safety functions
The kit works with DA/SA and LEM variants or the HK 4.1 trigger system. (Ensure you select the correct option.)
Included Grayguns Firing Pin Block Spring reduces stacking in DA pull and lightens trigger pull

Includes

The parts provided – control latch, extended sear roll pin, and firing pin block spring – must be installed together as a complete system.

Custom-designed Grayguns Control Latch
Custom replacement Firing Pin Block Spring
Custom replacement Extended Sear Roll Pin

Fit Guide

The kit works with all variants of the HK P2000 and P30 models without a thumb safety, including:

P30
P30L
P30SK
P2000
P2000SK

GrayGuns – HK P30 Straight Trigger

greg@tier-1.co.za — Thu, 14 Nov 2024 12:03:08 +0000

Description

Designed by Keith Hosey, Grayguns’ director of gunsmithing, the HK P30 Straight Trigger is a first-of-its-kind in the market. It fits all P30 variants. The trigger reduces over-travel while featuring a 90-degree optimal trigger break.

This P30 aftermarket straight trigger design allows for lower finger placement and may provide the feel of reduced pull weight, but it does not reduce pull weight.

Made in the United States to high-quality standards, guaranteeing the fit and finish Grayguns is known for. Precision machined from tool steel and heat-treated adequately for optimal wear resistance. Hand inspected and finished to ensure a quality trigger we can stand behind for life.

HK P30 Straight Trigger Fit Guide

This trigger fits all variations (LEM, DA/SA, and SAO) of the HK P30 line – and only the HK P30 line – of pistols. Including:

P30
P30L
P30SK

Fully compatible with the Grayguns HK P30 Short Reset System and HK P30 (with Safety) Short Reset System.

Finishes

Black Oxide

Our high-quality blued finish is our standard for this product.

Nickel PTFE

Electroless Nickel PTFE (Teflon®) is an advanced, self-lubricating, composite coating with PTFE particles co-deposited in the electroless nickel layer. Provides a hard, uniform, self-lubricating coating for our premium aftermarket triggers.

Physical Vapor Deposition (PVD)

This state-of-the-art process creates a molecular bond to the trigger, resulting in a durable finish. The PVD finish should not rust, discolor or tarnish. Availability varies, but options include Gray, Blue and Oil Rubbed Bronze finishes.

Titanium Nitride (TiN)

A well-proven standard layer type through its balanced properties. The golden titanium nitride layer, abbreviated TiN, indicates the following properties:

High hardness and adhesion
Good chemical resistance
Good temperature resistance in air
Relatively low thermal conductivity
Attractive, golden color
