NOTE: Gunsmithing Services are invasive and will most often (directly with tooling or indirectly with work holding) damage existing surface finishes on parts such as receivers. LRI offers a full menu of finish options for your components, please ensure you have also added an appropriate finish option to your cart if applicable.

GUNSMITHING SERVICES: Time/TIG and Time advance_Install handle to M700

  • $ 12500


 

New service as of 2026:   LRI Direct replacement bolt handles for M700s. 

The introduction of our machined replacement handles provides a viable solution to the issues that have plagued the M700 design since the early 1990s.  Our new handles replicate the feel of the factory design while improving important features overlooked by the OEM.

  • The strap portion of the handle now captures the entire back of the bolt cylinder.
  • The helical cam feature is correctly positioned to maximize primary extraction.
  • The handle-to-knob transition is tapered for a cleaner appearance when assembled.
  • Handle chamfer/clearance for radius fillet located in the bolt handle cut of the receiver*.

NOTE:  If you'd like your new handle to be completed with one of our Tac Knobs, see this link to add to your cart:  Add tac knob here

*A random issue with the M700 is the notched feature that the bolt handle rotates into.  Where the forward wall and floor of the notch are, a radius or "corner fillet" is often present.  It does not appear on every action.  The problem is that it prevents the bolt from fully closing.  Our machined handles have a chamfer added to the bottom/front to clear the obstruction, allowing the bolt to fully rotate into battery.

If you own an M700 with an RR prefix in the serial number, we strongly recommend this service when having the action accurized.  These actions have the latest handle revision from Remington, and the PE feature is almost non-existent.

Legacy Time and Tig, and Time and Tig with Timing advance:

Our Bolt handle fitting process for the M700 restores the Primary Extraction feature after the action has been blueprinted.  TIG (Tungsten Inert Gas) welding adds joint reliability by creating a stronger union at the shear point between the bolt handle and bolt body. The process we use is a combination of welding and soldering.  It delivers a very reliable means of permanently attaching the bolt handle to the bolt body. 

When working with blueprinted receivers, it is very common for the Primary Extraction function to require additional work.  Traditional "timing" involves positioning the handle to optimize the Primary Extraction cam interface with the receiver.  While this does work, we have adapted our service by adding material to the bolt handle's cam feature. 

This involves additional welding to "advance the timing" of the OEM handle.  We are restoring what should have already been there from the start.  Starting in the early 1990s, the RR prefix serial numbers for Remington M700s are the most lethargic in this area. 

The cam angle is incorrect, and the timing is grossly retarded in relation to the bolt's rotation.  Careful welding and machine work advances the cam position to correct the error.

Cam Surface advancement machining:

Welding and soldering:

Cleanup and final finish:

When completed, this operation advances the bolt timing so the primary extraction begins sooner in the rotation cycle while increasing the rearward motion of the bolt body.

What this boils down to is the powerful rearward tug on the fired cartridge as you rotate the bolt handle, which is what bolt actions are supposed to be known for.

Important information regarding this type of service:

TIG welding and soldering involve intense heat and the use of flux.  Flux is a chemical used to etch and clean surfaces in preparation for soldering.   These processes create discoloration and scale that cannot be avoided.  Because of this, the bolt and handle will require post op cleanup work.  This is done with abrasive blast media.  Carbon steel bolts and handles will require further finishing to protect from corrosion.   

Please make a note of these limitations before selecting this service.

You MUST send us your bolt and the receiver body for this service.  Other shops do offer handle attachment services without the receiver.  LRI does not.  Our experience is that the only reliable means of timing an action correctly is to have the actual receiver in hand, as it serves as the "GO-GAUGE" when installing the handle.
