Thread: No4Mk1* accuracy 'slip'

Just seen so many of these rifles- few pics from current trademe offerings- where the top woodwork has moved, touching the front sight protector. They just won't group like that! A few easy fixes around besides just checking before and after shooting but I expect it's caused all sorts of frustration if you don't know or notice. Could be the wood is a little shrunken with age. That could be partially remedied also. Unless the rile has been in some way bedded as in target style mods, the barrel should be floating all the way to the end of the fore wood where there is a 'seat' It should take around 3-5lbs to lift the muzzle end from it's seat and move smoothly back into place.. They tend to loose the tension with age and incorrect removal/fitting of the stock. They don't shoot well like that either (usually) Once again, several fixes are available. From looking at dozens of rifles over the years, most will have 1 or both problems present. Just the basics but really important to get right before trying different ammo, zeroing sights, scopes etc.

Fug that's ugly.

The other is a foreend that has a twist to one side, so that the muzzle doesn't sit straight in the barrel channel...

My No4Mk2 started off on Saturday morning without the forestock touching the front sight (as shown).
But 100 rounds later it was.
Annoying... and I'll use that as my excuse for shooting going to sh*t.

You prob know this, but the front bands come in several types and the usual issue is someone has replaced either the forewood or the band with the one that doesn't fit right... The band should have a bit on the back edge at the top that engages the recess in the top of the upper handguards steel tip, if it doesn't the thing can slide forwards under recoil until it hits the rear of the front sight bits. If this is happening, it's a case of making the recess in the metal tip fit the rear of the front band so that the front band is what is stopping the upper handguard sliding forwards, it might just be a stake punch in the rear of the top of the front band pushing the rear edge down enough to lock into the recess in the upper handguards tip, sometimes the recess needs to be extended rearwards a few mm as well. Hopefully that's clear enough as a description...

You can see on the photo 00buck posted that the middle band is tipped forwards slightly, and both handguards have slipped forwards - the only thing stopping the forwards movement is the front sight now.

The front band is retained on the foreend by the two cross pins, but the handguards can and will slip forwards like that unless the tip on the front handguard is securely held by the front band. Another option is cutting a piece of rubber to fit into the recess in the metal tip on the front handguard, and the front band clamping onto that - less invasive too.

I took off the front band and used needle pliers to bend a tiny bit of the back of the band downwards towards the recess. So catches the edge now. Same thing effectively as using a punch.
