T/C Compass First Generation – Installing a 2.5 lb Reduced Power Trigger Spring

This is one of the more satisfying jobs you can do on a budget bolt gun. An hour of careful work, basic tools, and your Compass goes from fighting you on every shot to breaking clean every time. Here is exactly how to do it right.

Before You Start – What This Job Actually Is

Installing a reduced-power trigger spring is not complicated gunsmithing. It does not require machining, fitting, or any permanent modification to the rifle. What it requires is patience, organization, and honesty about one thing: if at any point during the job you are genuinely unsure about what you are looking at, you stop and figure it out before continuing. You do not guess. You do not force anything. You do not fire the rifle until it has passed every safety test.

With that understood – this is a manageable job. Most Compass owners complete it in 15 to 30 minutes. The trigger assembly on the first generation Compass is straightforward, and the spring replacement is a direct swap. No special skills required, just methodical work and the right attitude.

For context on what the spring actually does and how to decide if this upgrade is right for your rifle and your use case, see the trigger spring overview on this site. The guide below assumes you have already decided to proceed.

Tools You Need

Nothing exotic. Set these up on a clean bench before you touch the rifle:

• Correct action screwdriver or hex/Torx key for your rifle’s action screws
• Torque wrench if you have one – useful for reassembly
• Small punch set and a lightweight non-marring hammer
• Small flat-blade screwdriver or a pick for handling springs
• Needle-nose pliers
• Non-marring mat or folded towel to work on
• Phone for photos – more useful than any other tool on this list
• Trigger pull gauge – strongly recommended, not optional in my book

On the pull gauge: you can complete this job without one, but you will have no idea where your trigger actually ended up. “Feels lighter” is not a measurement. A pull gauge costs less than a box of good ammo and tells you exactly what you have. Get one if you do not already own one.

Safety First – Non-Negotiable

Before anything is touched:

• Remove the magazine
• Open the bolt and lock it to the rear
• Visually inspect the chamber – look, then put your finger in and feel
• Remove all ammunition from the bench and the room if possible
• Keep the muzzle pointed in a safe direction throughout the job

Once the action is out of the stock, do not pull the trigger for any reason until you are ready for the controlled safety tests at the end. That is a rule, not a suggestion.

The Installation – Step by Step

Step 1 – Remove the Bolt and Separate the Action From the Stock

Confirm the rifle is unloaded one more time. Open the bolt fully. Find the bolt release – on the first generation Compass it is a small lever at the rear left of the action – depress it and pull the bolt straight back and out. Set the bolt somewhere it will not roll off the bench.

Use the correct driver to remove the action screws. The Compass typically has two – one in the front guard and one in the rear. Keep track of which screw came from which hole; on some rifles they are different lengths. Lift the barreled action straight up and out of the stock. Set the stock aside where it will not get bumped.

Step 2 – Get Oriented Before You Touch Anything

Place the barreled action upside down on your mat so the trigger group is facing up and accessible. Take a moment and just look at it. Identify the trigger housing, the trigger shoe, and the pins that retain the assembly. Find the trigger spring – on the first generation Compass it is the main return spring that applies tension to the trigger shoe.

This is the moment to take photos. Shoot the trigger assembly from multiple angles with your phone before any part moves. This costs you thirty seconds and can save you thirty minutes of puzzling over reassembly later. Do not skip this step.

Step 3 – Remove the Factory Spring

Using your punch and light taps from the hammer, drift out the pin or pins that need to move to access the trigger spring. Work slowly and support the action so nothing flexes or gets stressed. When you have access to the spring, note exactly how it sits – which end goes where, which direction it tensions – and take another photo if needed.

Use your pick or needle-nose pliers to lift the factory spring out carefully. Set it somewhere you will not lose it. You want to be able to reinstall it if something goes sideways.

Step 4 – Install the 2.5 lb Spring

Seat the new spring in exactly the same orientation as the original. Both ends should be fully captured in their pockets or notches – nothing should be resting against something it should not be touching. This is the most important part of the job: a spring that is seated wrong can cause the trigger to behave unpredictably or not reset at all.

Reassemble the trigger components in reverse order. Drive the pins back in carefully – fully seated, flush where they should be flush. Once everything is back in place, manually move the trigger shoe with your finger and confirm it moves freely and springs back cleanly under the new spring’s tension. It should feel noticeably lighter than the factory setup already at this stage.

Step 5 – Reinstall the Action in the Stock

Set the barreled action back into the stock, making sure it sits correctly in the inletting with no binding or misalignment. Install the action screws and snug them evenly before final torque. If you have a torque wrench, use the manufacturer’s recommended values – the Compass manual lists the correct specification. If you do not have a torque wrench, snug them evenly and firmly without cranking them. Reinstall the bolt.

Measuring the New Pull Weight

Confirm the rifle is unloaded. Cock it by cycling the bolt. Attach your trigger pull gauge to the center of the trigger shoe – not on the edge, not off to one side, centered. Apply smooth, straight rearward pressure until the trigger breaks and note the reading. Do this five times and take the average. Small variation between pulls is normal; large variation is not and needs investigation.

Most first generation Compass rifles with this spring installed end up somewhere between 2.5 and 3.5 lb. If your rifle comes out at 3 to 3.5 lb instead of a precise 2.5 lb, that is still a genuine transformation from the 5-6 lb factory pull – and it is a perfectly practical hunting weight. Do not chase a number obsessively. Chase a clean, consistent, predictable break.

If the pull is significantly outside the expected range, or feels rough or inconsistent on multiple pulls, stop and investigate before going further. Check that the spring is fully seated, that no pins are proud, and that the stock is not contacting the trigger housing once reassembled.

Safety Testing – The Part That Actually Matters

Pull weight measurement is step one. These four tests are what confirm the rifle is actually safe to fire. All tests are performed on an unloaded rifle. No exceptions, no shortcuts.

Function check: Cock the rifle and press the trigger. It should release cleanly and consistently. Cycle the bolt and repeat several times. The trigger must reset and feel the same every time.

Safety check: Cock the rifle and engage the safety. Apply firm, normal firing pressure to the trigger. The sear must not release. Take the safety off and confirm the trigger functions normally again. If the safety does not fully block the trigger, stop immediately – the rifle is not safe.

Bump test: Cock the rifle with the safety off. Hold it firmly and bump the buttstock solidly against your palm or a padded surface. Do this several times. The firing pin must not release. This test matters – a cocked rifle gets bumped in the field, and you need to know it will stay cocked until you tell it otherwise.

Drop / slam test: Cock the rifle and, from a couple of inches above your padded surface, let the butt make firm contact. The firing pin must not release. Reduced spring tension means less resistance against inertia – this test confirms the sear is still doing its job under impact.

If the rifle fails any of these tests, it does not go to the range and it does not go hunting. You reinstall the factory spring, correct the issue, or take it to a gunsmith. A rifle that fails a safety test is not a project to push through – it is a problem to solve before the rifle is used again.

After the Job – Maintenance and Long-Term Care

A light spring means the trigger mechanism benefits from staying clean and lightly lubricated. Avoid flooding the housing with heavy grease – thick lubricant attracts grit and can slow the mechanism, especially in cold weather. A light wipe of gun oil on contact points is all you need.

After hard use, blow out the trigger housing with compressed air or a soft brush. Check that pull weight and safety function still feel normal. Any change in feel – especially unexpected lightness, inconsistency, or a spongy sensation – warrants a bench inspection before the rifle goes out again.

If you ever notice the firing pin releasing when the bolt is closed firmly or when the rifle is bumped, stop using it immediately. That is a gunsmith call, not a DIY troubleshooting session.

The Result

When this job is done right, the first generation Compass stops being a rifle you tolerate and starts being one you enjoy. The barrel was always capable. The action was always solid. The trigger was the one thing holding the whole package back – and now it is not.

Most owners describe the same thing after their first range session with the new spring: the rifle finally feels like the sum of its parts. Groups tighten up because you are no longer fighting the trigger at the moment of the shot. The confidence that comes from a clean, predictable break is real, and it shows on paper.
