Re: modle 700 trigger problem
FG - If you have some "Cold Blue", with a swab, put some on the sear where the cocking piece makes contact - and also where the cocking piece starts to ride over the sear, as it moves forward, depressing the sear. If the sear colors the chrome plating is warn through increasing the coefficient of friction at the mating surface of the sear and cocking piece.
Typically when this occurs, the rifle will "fail to fire" when the trigger is intentionally pulled, but will instead discharge when the bolt is touched --- which is not the malfunction you are describing.
What you are describing is what Remington has termed an "FSR", or fire on safety release.
The FSR is the most common form of malfunction associated to this trigger design, as evidenced internally by the manufacturer as early as April 1947, which predates release of this fire control in the M/721 by roughly 11 months, which was released to the public in March of 1948.
The FSR malfunction has been a very persistent form of malfunction for Remington, and the public.... Also, the powder metal used for the sear was a poor choice of material, not suitable for sear construction. Powder Metal was used as a cost saving measure that increased the instances of fire control malfunctions after it was adopted in about 1968.
Replace the fire control and never look back! I would also recommend that you destroy the offending fire control to ensure that it does not find its way into someone's rifle in the future.
