I have a Brookfield Scope Mount on my Springfield M1A’s and have been experiencing malfunctions. During case extraction the cartridge has been getting jammed between the Scope Mount and the rifle’s bolt. I have been getting jams approximately every 20 rounds fired. When the jam occurs, the cartridge is wedged between the scope and the bolt and requires using pliers to pull the cartridge free. The following is my rifle’s specification.
• Rifle – Springfield M1A
• Barrel – Standard weight GI Barrel, TRW -1962
• Bolt – TRW
• Ammunition Used – Military M118 Special Ball and M118LR ( No Reloads)
• Bolt and Receiver are well lubricated
• Normal extraction pattern at the 1:00 position without the scope mount installed
I have shot the M14 for many years in competition but just started using this rifle for tactical matches. I have never experienced any malfunctions with this rifle prior to installing the Brookfield scope mount.
If you have any suggestions to solve the jamming problem I would be extremely appreciative.
