This kit includes our extended magazine release lever and a replacement torsion spring. Regardless of whether you are using OEM Remington magazines or higher capacity magazines, this kit is essential for fast and fumble-free releases. It is also useful for those that shoot wearing gloves and/or in low light conditions. Our lever is CNC machined from hardened 17-4 grade stainless steel and finished with a tough DLC coating (black color), and the spring is coiled from stainless steel. This is a durable replacement that will never wear out, is highly-resistant to corrosion and has been made from the best materials with the best finishes applied. The deep serrations provide a very grippy surface for all weather conditions and are on both the bottom and front faces to accommodate individual shooting preferences.

This kit comprises of both a replacement hammer spring as well as five different trigger springs ranging in pull weight from 1.25lb to 5lb. The hammer spring is made from stainless steel, and the trigger springs are made from spring steel then plated for both easy identification and to maximize corrosion resistance. This high quality set of six springs fits nearly all Remington pump and semi-auto rifles and shotguns – which use the trigger assembly as pictured. Aside from three lighter pull weights, the kit includes a factory weight spring should you wish to bring your trigger back to original specification, as well as a heavier spring for cold climate shooting with heavy gloves. The new hammer spring will both correct light primer strikes due to an old or worn spring as well as correct/improve lock time – the proper function of both being crucial for maintaining accuracy. If unsure on compatibility please contact us first to check. We measure the factory trigger at 4lb (based on the Remington 7600 rifle), the ratings below can vary slightly when fitted to different firearms* and when installed correctly**.

• Ultralight 1.25lb to 1.5lb (black color)
• Light 1.75lb to 2lb (silver color)
  
• Medium ~3lb (grey color)
  
• Factory ~4lb (charcoal color)
• Heavy ~5lb (light blue zinc color)

Notes

Although the springs provided in this kit have been designed and tested by us to be safe, every trigger is different and it is imperative to ensure that your trigger is safe after installation. We have come across some very unsafe 1lb springs for this trigger assembly which although break at the advertised pull weight, will slam fire when working the action hard or when dropping the firearm onto the buttpad. Be vigilant with all trigger modifications and test thoroughly after reassembly! In our own tests, 1.25lb is the minimum pull weight that this trigger assembly will achieve by replacing the spring and polishing the sear and hammer. By replacing the trigger spring alone you can expect 1.5lb in an unmodified trigger assembly.

* Results may vary slightly between individual rifles and shotguns and are dependent on the trigger pull gauge, factory tolerances and whether any other modifications have been done to the trigger. Our pull weight is measured using an RCBS gauge.

** We supply replacement springs only. If unsure on installation, we highly recommend having a qualified and competent gunsmith do the job. Slight variations between different rifles and shotguns may result in an unsafe trigger when fitting these springs. Always ensure the firearm is unloaded before commencing work and test trigger function extensively upon reassembly whilst rifle is unloaded. Slam closing the breech bolt and dropping the firearm onto the buttpad (both whilst unloaded) is imperative.

Striker spring kit / Firing pin kit

• Experiencing light primer strikes or a complete failure to fire cartridges?
• Already tried different brands of factory ammunition?
• Already tried reloading with different primers?

Our striker spring for your Tikka T3 / T3x is longer than the OEM spring and is manufactured from high quality piano wire then zinc plated (silver color) to resist corrosion. We also include at no extra cost a higher power spring (gold color) made from thicker diameter wire which is approximately 10% stronger (if installed at full length). This higher power spring can be used to remedy primer ignition issues caused by insufficient spring pressure or for those competition shooters looking to chase faster lock times, however in many cases it will require between 1 to 4 coils cut off to function as desired in your rifle.

When stripping the bolt assembly for cleaning and maintenance, the striker pin is often overlooked. Our kit allows you to refurbish these critical components after a thorough cleaning rather than reinstall worn or damaged components. Keeping a spare set on hand (and the tools to change them) also serves as cheap insurance for any upcoming expeditions.

Contents

• 1 x ‘standard’ striker spring (27.2 coils, 1.4mm wire – silver color)
• 1 x ‘higher power’ striker spring (30.0 coils, 1.5mm wire – gold color)
• 1 x retaining collet
• 3 x 5mm snap rings

Construction

• The striker springs are made from a high quality spring steel then zinc plated
• The snap rings are made from stainless steel spring wire
• The retaining collet is CNC machined from pre-hardened 17-4 grade stainless steel then TiN coated to the gold color (the original Tikka part is made from an aluminum alloy)

Recommended Tools for Workshop Installation

• Engineers offset vise (to be modified as below, requires a hand drill and various HSS bits)
• Small nylon-jawed pliers (we use bracelet bending pliers bought from ebay)
• Small needle nose pliers
• 1200 to 2000 grit aluminum oxide paper
• G96 gun treatment or a similar product
• Microfibre cloth

Fitting Guide

This can be a difficult part to replace and is best done in a modified offset vise or a custom-made jig designed to compress the Tikka striker pin assembly safely. The disassembly then reassembly under spring pressure is what makes it difficult. The following steps are how we install this kit which is also shown in the image gallery. If in doubt we recommend a gunsmith installation.

1. Wear safety glasses and do not stand in front of the compressed striker pin assembly at anytime.
2. The striker pin can be compressed safely in a modified engineers offset vise (or similar). The vise will need a minimum of two small holes drilled in adjacent surfaces. The striker pin hole for assembly needs to be 5mm or 13/64″, and the cocking indicator hole needs to be 6.5mm or 17/64″ (see image gallery). The alignment of these holes needs to account for the offset of the cocking indicator to the striker pin axis (the cocking indicator orbits the striker pin). Drill the striker pin hole first then position the assembly to mark out the position for drilling the cocking indicator hole.
3. If your bench vise is made from thick material, we advise drilling a larger diameter hole just prior to the striker pin hole to accommodate the collet so that when the striker pin is compressed the snap ring is sufficiently exposed so that it can be pried out (see step #4).
4. Secure the striker pin assembly by inserting both ends into these holes ensuring a snug fit. Slowly close the vise jaws sufficiently to compress the striker spring so that the snap ring contained underneath the collet is exposed. We also drill a third, slightly larger striker pin hole (5.5mm) for the disassembly step which allows the snap ring to travel through the vise face but locks against the collet. This is optional but makes disassembly easier in our experience.
5. The snap ring can be pried open using the tips of two small stanley screwdrivers or a similar tool and then pulled out using nylon-jawed pliers.
6. Dispose of the old snap ring and slowly open the vise jaws, removing the striker pin assembly once the striker spring is fully decompressed.
7. Thoroughly clean the striker pin and other components to be retained, remove any burrs (see steps below in ‘Maintenance’). Our collets are turned to tighter tolerances than the Tikka factory part you are replacing, at this step we clean the striker pin with 2000 wet and dry after removing any burrs to ensure a tight but functional fit to the collet. The striker pin can be polished beyond this if desired.
8. Reassemble using our spring kit by repeating the process above however install the snap ring in front of the collet prior to inserting it back into the vise ensuring the striker pin is in the 5mm sized hole. The new snap ring will expand as it is pushed over the diameter of the striker pin and then close again once it reaches the slot.
9. Once the snap ring sits into the slot, use the nylon-jawed pliers to pull back the collet, then compress the snap ring using small needle nose pliers or a similar tool so that it can then fit under the new collet. Opening the vise whilst squeezing the edge of the snap ring will see it slide under the collet. Ensure the new snap ring is completely enclosed by the new collet.

Maintenance

Clean all scale and debris off the striker pin using a suitable gun solvent and then inspect the pin surface to ensure it is burr free. Any burrs can be removed to achieve a smooth/polished surface by starting with 1200 grit wet and dry paper then working up to finer grits from there. Using an ultrasonic cleaner works well for really dirty striker pins. Spray the striker pin with G96 and cleaning thoroughly using a microfibre cloth until it is touch dry, don’t apply grease anywhere. Our entire kit is made from high quality materials and is resistant to corrosion. Discoloration around the tip of the striker pin is normal and is due to the heat treatment applied during manufacture.
