Size and length for rear screw for barreled action?

[D. "Average" Jo]

Good day,

I'm trying to find the size and length for the allen key to remove the rear tension screw install some parts, but your user manual doesn't have any of the information.

It also talks about a second set of screw, which I have no idea what it is.

The rear tension screw seems to be a 3/32 Allen. There are two with the second one acting as a lock to secure the first that contacts the trigger group. The manual references T25 key head screws but I don't see any. I've only had mine about 30 minutes though. LoL

The one in your picture is the main action bolt and is 5/32 Allen.

The screw info is
Black Oxide, 10-32 Thread, 1/8" Long
uses a 3/32" hex key

The screw is meant to be snugged up against the rear of the trigger group. Do not over tighten as it will run the trigger housing and possibly cause interference issues with the return spring / rod behind the hammer.

The send screw (same kind as the first) is meant to be snugged up behind the first to prevent the first screw from loosening off.

Chassis the ship now some with a colour install guide, covid delayed boxes and manuals on us.

Let us know if you have any questions. We are planning to shoot a video on the install some time before all fire arms are banned.

Thank you for the information everyone.

I was able to take the screws off no problem.
