#4Mk 2 question..

[SA85M1]

Dragged home the first #4Mk 2 on saturday..and was wondering why they had the trigger assy attached to the reciever ? What was the need to change it ?..I have never seen a trigger issue with a #4 Mk 1...

You won't see a trigger pinned to the body on an original Mk. I or Mk. I*. Introduced with the Mk. II.
The Mk. II system produced more consistent trigger pulls.
Many Mk. I, Mk. I* rifles were converted to this system during UK rebuilds.

Attaching the trigger to the receiver was done to improve accuracy and consistency, also if the wood swells on a No4 MkI it can apparently change the trigger to sear relationship.

Hmmm..that makes sense, did they convert any of the Mk 2 's into sniper rifles ?...

Not sure if they did, but I did. The repro I built was on a No4 Mk1/3 Long Branch

The Mk. II was post WW2. Were any No. 4Ts set up post war? L42s are converted 4Ts, so I would not expect that either 4Ts or L42s would be based on the Mk. 2 action.

This interesting article is accompanied by a detailed photo montage of a previously damaged skeletonised No.4(T) rifle, used as a training piece for budding Armourers to learn with and develop their skills. As Peter says "It appeared that this ‘rifle’ had never been finished as a ‘T’ as the front pad hole had not been drilled. During bead blasting after a hard life as a skeletonised rifle, it was established that the screw had sheared off and simply been made off level. Drilled out and extracted, it’s back to its former self. Waste not, want not as they say…". Other photos in the article show the clear interaction of the sear, cocking piece and trigger during various phases of its operation.

Article Extract .....

Pictorially, this shows the trigger at the end of the first pull, both ribs touching the trigger bent or flat of the sear with the sear nose at the extreme edge of the cocking piece………, just ready for the off.

The only sniper rifles built on the no4mk2 action was the "Enforcer" police marksman rifle. Some were sold to Singapore and I believe Belize...

Some existing No4mkI(t) snipers were converted to No4Mki/2(t) status, both by the British and by the Indians.

Hanging the trigger on the trigger guard was not one of the better ideas. In fact, it was pretty stupid. It can cause nothing but trouble for bedding and trigger pull.
