The Ultimate Spyder Hammer 7 Guide

by CJ DromaJune 22, 2016

Introduction

Paintball has seen a bit of a shift over the last several years as magazine fed marker technology has improved. Parallel to magfed’s increasing popularity is that pump has seen a fierce resurgence as well and is as popular as ever before. So why not combine the two? That, in a nutshell, is what Kingman did with the Spyder Hammer 7 marker: a magazine fed pump action milsim style marker built and priced as an entry level marker.

The Hammer 7’s slim profile, low cost and pump action has encouraged intrepid modders to come out of the woodwork to hack the platform into a myriad of configurations rarely seen on the field. Whole communities have sprung up around the unassuming marker to share and encourage others to build their own custom configuration ranging from Frankenstein builds to elegant sniper configurations that would make real steel marksmen jealous.

This guide is intended to provide a great starting place for new and veteran players alike to find commercial off the shelf, bolt on modifications as well as find inspiration if they feel confident enough to hack their marker into a shotgun or a sniper rifle platform.

The Marker

The Hammer 7 is a Nelson Based pump action marker that can be switched between hopper fed and magazine fed using Spyder’s new (at the time of release) Dual Loading Capability (DLC). Unlike Spyder’s Dual Loading System (DLS) that can be switched on the fly, their DLC system can only be switched off the field, requiring an allen wrench to remove a top plate and physically rotating an internal part.

The overall styling of the marker resembles a shotgun, which some enterprising modders have taken and absolutely ran with (see below). On top is a picatinny accessories rail. Like other Nelson based markers, the ASA is located on the back of the marker as opposed to a grip mounted ASA commonly found on markers in the same price bracket.

On/Off ASA AdapterOnOff ASA

Description:  Some builds make it a multi-step process to remove a tank when storing the marker in between trips to the field. Leaving a pressurized tank on your marker during storage wears out springs and o-rings faster. This On/Off adapter installs between your marker and tank to provide a way to turn off the air supply to the marker, removing pressure from the internals and thus extending the life of your marker.

Barrels

These are the most popular and most recommended barrels for the Hammer 7. Any Spyder threaded barrel will fit/work with the Hammer 7 giving you a large market of barrels and barrel sizing kits to fit your needs, aesthetics and play style.

The stock Hammer 7 barrel is a fantastic barrel in its own right. A lot of players stick with the stock barrel for their build as the looks and performance are pretty good out of the box. As always, flex honing the barrel can potentially improve performance.

 

 

 

NOTE: The modifications presented in the following sections are permanent, non-reversible and WILL void your Spyder warranty. PaintballTech.Net does not endorse nor encourage making these modifications. This section is to demonstrate what other players have done to suit their individual needs and desires. Should you choose to make these modifications PaintballTech.Net cannot be held liable for any damages or consequences resulting from individuals attempting the following modifications.

 

The Shotgun Build (The Bodi Build)

As mentioned above the Hammer 7 is stylized to loosely resemble a combat shotgun. Several enterprising individuals took it upon themselves to improve upon that look. Enter Jason Bodi (pronounced boh-d-eye) whose Hammer 7 “Warlord” build has captured other player’s interests and ignited their own passions to imitate it. Jason may not be the first to modify his Hammer 7 in such a fashion, but the sheer amount of work and detail has certainly made it the go to template for a Hammer 7 shotgun build.

The Sniper Build

The Hammer 7 is a (mostly) square narrow bodied marker, especially when you exclude the pump handle. This narrow profile has lent itself to slotting into various long rifle stocks (with heavy modifications). There are as many “Sniper” builds as there are stocks, all you have to do is Google “Spyder Hammer 7 Sniper” to see the myriads of stocks this humble marker has been dropped into. Some range from quick, cheap and dirty all the way up to hundreds of hours spent getting the marker to fit perfectly and look just so .

Part of the point of the sniper build is to do away with the pump handle up front, instead going for a bolt action style modification. A major problem with this is that the marker is designed to apply pressure to both sides of the bolt; when changing it over to a bolt action rifle you’re changing it to pump from one side of the bolt only, causing wear on the bolt that it was not designed to handle. A decent bolt action handle is usually sufficient to apply mechanical force on the bolt without torquing it the wrong way. Some players went so far as to build a frame or harness that connects to both sides of the bolt, but allows them to cock it one handed.

Lever Action Build

What’s a stock-based rifle or shotgun without a little lever action? Not as popular of a build due to the difficulty of the lever action, some dedicated and enterprising individuals took it upon themselves to recreate this once ubiquitous cocking action into their Hammer 7 builds. An example of this build can be seen in the players gallery below.

Feed System Modifications

RAP 4 DMAG Magazine Wellmkv-dmag-magazine-well-1

Description: DMAG’s and Helix mags are very well received by players, as such modders have taken MCS magazine wells and installed them on their Hammer 7’s. There are multiple MCS magazine wells, be sure to research each to ensure you find one that suits your project.

Cost: $

 

 

DYE DAM Magazine Welldye magwell

Description: Dye magazines are very well received by players as well, and like the MCS magazine well there are players that have modded their Hammer 7’s with a DYE DAM magazine well.

Cost: $

 

NovaTactical_Spyder-to-Zeta_Magwell_AdatperTrufeed (Tippmann Magazines) Magwell Adapter

Description: As of publication I couldn’t find a separate magazine well for Tippmann Trufeed magazines. Instead, Nova Tactical Designs has an adapter that slips into the existing magwell that allows you to use Trufeed magazines, including Stark Pursuits’ Zeta Magazines.

Cost: $

 

 

 

 

 

T68_Firestom_Pistol_20_Round_Magazine_largeMCS 20 round Spring Fed Magazine Tube

Description: Used for Shotgun builds. Not designed to bolt directly onto the Hammer 7 as it requires a collar over the feed hole on top of the marker as well as a bracket to hold the backend of it to the end of the barrel. NOTE: The deflector at the end of the tube isn’t optimum, multiple players have reported that paintballs often get stuck before feeding into the breach.

Cost: $

 

Empire Feed TubeEmpire 10 round Spring Fed Magazine Tube

Description: Similar to the MCS feed tube, enterprising players have hacked this onto their Hammer 7 markers.

Cost: $; discontinued by manufacture Spring 2016, limited to stock on hand at various online shops.

 

 

Magazine Mods

Change the spring

Description: Some players have swapped out the spring for another one in order to address the magazine follower issues. Others have modified the stock spring by either cutting the spring, or stretching it out. As of publication I do not have sufficient evidence to support the claims of either mod, proceed at your own risk.

Mod Type: Performance

Technical Difficulty: Low, requires magazine disassembly

Time to Complete: 30 minutes

 

Smooth Paintball Channel

Description: The follower gets caught up inside the magazine sometimes, especially when there’s dirt/grim lodged in there. Some players have taken it upon themselves to disassemble the magazine and polish the paintball channel to decrease resistance on the follower, and as a result (hopefully) reduce the number of feed issues.

Mod Type: Functionality

Technical Difficulty: Medium; requires magazine disassembly and attention to detail

Time to Complete: >30 minutes

 

Gently Round the Square Head

Description: The square head on the magazines can interfere with changing magazines swiftly. Some players round off the edges (gently!) to improve magazine swap performance.

Mod Type: Functionality

Technical Difficulty: Low

Time to Complete: <15 minutes

 

KG-Factory short Spyder magazine dummy

NOTE: This picture is for a KG Factory “dummy” magazine; this image is used strictly as an example of what a short magazine could look like after modification.

4 Round Sniper Chopped Magazine

Description: Sniper builds rely on stealth and maintaining a low profile, often in a prone position The standard 9 round magazine is tall and can interfere with such operations. To remedy this players have either chopped their magazines into a shorter profile, or if they had access to a 3D printer, they have 3D printed shorter magazines.

Mod Type: Functionalilty, Aesthetics

Technical Difficulty: High, precise measurements required

Time to Complete: >60 minutes

 

Miscellaneous Modifications

MagPul MOE Pump GripPump Handle Modifications

Description: For shotgun builds a popular modification is to take a shotgun style pump handle and graft it onto the Hammer’s existing handle. Due to the aggressive and modern look, Magpul is a popular choice among players.

Mod Type: Aesthetics

Technical Difficulty: High; requires a high degree of cutting, shaping and sanding

Time to Complete: >60 minutes

Cost: $-$$$

Troubleshooting

PROBLEM: Air Leaks Down The Barrel
SOLUTION: 1. Cup Seal is bad and needs to be replaced. (SEE CUP SEAL REMOVAL)
SOLUTION: 2. The Power Tube Valve Seat could be nicked / scratched and needs to be replaced.
NOTE: Never remove the Power Tube Valve Seat unless specific repairs are needed.

PROBLEM: Paintballs Break In The Marker
SOLUTION 1. If the weather temperature is below 59°F (15°C) or above 86°F (30°C) paintballs can become brittle and not  hold up to the Markers Velocity and outside temperature. Paintballs have a shelf life and can become too frag-ile for use. Paintballs can take a different shape in time so would be wise to size the paintball with your barrel.  Dirt or broken paint shell fragments in the barrel can cause the Marker to continue breaking more paint down the Barrel. Using a squeegee down the Barrel will remove most of the dirt or broken shell fragments. (SEE SQUEEGEE CLEANING OF THE BARREL AND BREACH)
SOLUTION: 2. If your pumping the Marker and don’t have a consistent rhythm while the loader is feeding the paintballs can get pinched or wedged in the breach and this could cause a paintball break.
SOLUTION: 3. If the Marker had been cocked twice in a row and loaded 2 paintballs at the same time this could cause a paint-ball break.
SOLUTION: 4. Velocity adjustment is too high and needs to be lowered to proper velocity (fps) speed

PROBLEM: The marker “Burps” when pumped
SOLUTION: 1. Unscrew the pump rod 3-4 turns, continue to adjust as necessary until it is no longer “burping”
SOLUTION: 2. Place a nickle and 2-3 pennies stacked together in the pump handle ahead of the pump rod. Use temporary adhesive to keep in place.

PROBLEM: Low velocity when using HPA
SOLUTION: 1. Ensure your HPA has an output pressure of ~850-950PSI, the same as CO2 as the Hammer 7 is designed to operate at those pressures. (Most HPA tanks output ~800PSI or less).
SOLUTION: 2. Purchase a SHP (super high pressure) regulator or tank that outputs ~850PSI+
SOLUTION: 3. Purchase CO2 tank

PROBLEM: Marker loads 2 rounds (or more)
SOLUTION: 1. Replace detent
SOLUTION: 2. Install an EGO detent in place of a Spyder detent. Edges may require a little trimming to fit correctly. Works best for roundball; may be too soft for FSR only builds.

PROBLEM: Marker won’t cock or jams after maintenance
SOLUTION: 1. Disassemble the marker and ensure the bolt is installed correctly (it can be installed upside down which will cause these issues)

PROBLEM: Magazine Fails to Load the last 2-3 rounds properly
SOLUTION: 1. [solution forthcoming]
