Remington 700 offset external bolt stop installation: Method 3
In our first post on installing an external bolt stop for an M700, we made a step cut into the receiver above the bolt stop. In the second post on external M700 bolt stops, External Remington 700 bolt stop- no step cut installation- method 2, we decided to go for a different look, by removing the step cut.
For comparison purposes, this is what the final installation of the “no step cut” method looks like:
Compared to the method shown in the first article:
Our third method, shown here, will offset the bolt stop, eliminating the need to cut a clearance slot in the rifle’s stock.
The bolt stop is a “Lawton/Nosler” style bolt stop from Pacific Tool and Gauge.
We ordered the following supplies from Brownells (part #):
- 3/16″ Solid carbide 4 flute center cut end mill (317-111-312WB)
- 1/16″ drill bit (891-201-160WB)
- #1 Solid carbide center drill (317-402-001WB)
- Do-Drill cutting oil (083-007-016WB)
- 1/8″ detent spring(080-820-125WB)
- 700 receiver facing mandrels (521-103-000)
An ample amount of time was spent planning the installation. Planning is necessary to ensure that the bolt stop has ample room on each end to function (we used .007″ on the front, .060″ on the back), doesn’t impede functioning by stopping the bolt too early, pivots in the correct location, and has appropriate support on the front and rear. Some of the measurements we used will be shared, however, if you plan on installing one, you should develop your own calculations and proceed with caution. Keep in mind, if the bolt stops is too short it may not extract a loaded cartridge or feed from the magazine.
Do not use a roll pin for the bolt stop. It is too weak and will shear. We use a 1/16″x1/2″ piece of hardened drill rod for all of our stops.
