Sniper Rifle build

Operational Detachment Alpha 420

GUN Review

This review/build is for my JG Bar 10 Bolt action sniper rifle. As I go along I will be installing various parts and some do it yourself modifications to it to make it perform better and hope fully reach the goal of around 600FPS with.20g BB’s, (You use  the .20g bb’s for base line chono for FPS as most fields this is the standard.) I will be using .43g BB’s when I field it. And will give you the FPS with those also.

The parts are being purchased from MadDawg Paintball and Airsoft in Stanwood Wa.

As I instal  each part of the build I will give you a base of FPS and a description of the parts that were installed and the pro and cons of each part.

Angel Custom "OMEGA" Zero Trigger System For VSR-10 Airsoft Bolt Action Sniper Rifles

About Angel Custom "Alpha" & "Omega" Professional Zero Trigger System:
The Maruzen's APS / Type96 and Tokyo Marui's VSR10 system are among the two most popular bolt action sniper platforms. The Marui VSR10 system offers great trigger response while lack the ability to manage high power upgrades. The Maruzen system offers the ability to take high power upgrades but lack everything else. The Angel Custom Alpha and Omega trigger system combined the best of both worlds to bring you the ultimate trigger set for your ultimate sniper rifle build.

· Angel Custom Omega Pro Trigger System: True Zero trigger for fastest response possible. Designed for advanced users. The Omega Pro Zero trigger system is a true zero trigger re-designed (120% improvement) after the Laylax zero trigger system. Compare to the Alpha system, the Omega system is much more complex in design, with less safety features (a drop of rifle may trigger the rifle, so it is critical that you transport it unloaded), but an UN-matched zero trigger response. The Omega system is recommended for advanced shooters only.
Specifications / Features:

· Advanced Trigger System for the ultimate "zero" loading trigger pull.

· Provides smooth cocking, comfort loading, and light pull trigger action.

· provides the necessary durability for high power operation and upgrades.

· Integrated modified trigger sear, piston sear and trigger bearing to allow a full range of power upgrades.

· The OMEGA trigger system provides an adjustable trigger sensitivity for advanced shooting requirements and habits. (Clock-wise for lighter pull and counter-clockwise for heavier pull. Avoid over-screwing.)

· The Alpha trigger system retains the original safety function.

· Each "Alpha" Pro Zero Trigger system is individually fine-tuned by Angel Custom certified technicians.

· Designed to provide minimal friction for a fast response and light trigger pull under high power upgrade. (The stock trigger box will experience strong tension and friction after high power upgrades.)

· Stamping Steel Armor Plate with SUS axle joint.

· CNC Swedish S136H Steel Internal Sear Set.

· 100% Full CNC High Carbon Steel (H.C.S.) Trigger.

· the original 45 degree piston design creates unnecessary friction with the Cylinder. The OMEGA trigger's second piston sear will catch the integrated 90 degree piston properly to maximize durability and stability.

· MAX Piston and Cylinder Head Set included.

· Special piston head and SUS304 Cylinder Head design allow MAX air seal, directed air flow and quite operation.

· Integrated Teflon spacers to further reduced frictions.

· there is some modification that may be required, professional installation recommended.
Materials: CNC Aluminum Plate with SUS axle joint, Carbon Steel Sear Set and Internal Parts
Package Includes: Complete Omega Pro Trigger System, VSR10 MAX 90 Degree Aluminum Piston with Steel End Cap, Stainless Cylinder Head
processing: 100% CNC / Anodized.

The Angel VSR-10 Cylinder Head and Piston Head: The inherent design flaw of the Tokyo Marui VSR-10 is its original 45 degree piston head. When a M150 or higher power spring is installed, the piston sear will start to stress the piston and moving the piston forward. As a result, the piston will experience a large amount of friction with the cylinder when you pull and push the bolt. The complete Alpha Pro Trigger System allows provides a Piston featuring a 90 degree aluminum piston with steel end cap and a new concave front end design as well as a stainless cylinder head with concave rear end design.

The only con that I see so far with the Omega trigger set up is that the Cylinder heads is taller than the stock set up.

The stock cylinder head is: .344” for the threads and is .474” tall

The Angel Customs r Stainless Cylinder Head is: .417” for the threads and is .565” tall

You can see the difference in the height of the cylinder heads in the picture

               

                

 

The stock piston is made of plastic and has a built in “air break” on the front of the piston

 The Angel Customs piston is made CNC Aluminum Piston with Steel End Cap. This piston and produced better compression and it should help keep consistency for the FPS and performance.  

 You can see the difference in the pistons in the picture.
