FX Impact bolt flop

[myers129]

Has anyone come up with a good solution to keep the bolt handle on the Impacts in the forward position while hunting and moving around? I carry the rifle slung across my chest with a vickers sling, muzzle down but the cocking block keeps coming out of battery and double loading is a very real problem for me. I was contemplating a stronger spring on the silver plunger in the block, maybe that would keep the bolt handle cammed over better?

In red above...the "forward" position ? The arm should be locked closed, in battery...ready yo fire, in this position !
Or do you mean the open position, arm "sticking out", so when you bump in, THEN...it's in the cocked position.

If I'm understanding your problem...
The Air Marksman rail is your savior. They have three lengths out over the barrel.

I am having trouble with my rifle coming out of battery, bolt bouncing enough that the pellet probe allows the magazine to rotate and then if I return the rifle to battery I am double loaded. I missed a couple of squirrels this year and after reviewing found I had a double thud against the tree and was shooting low due to two pellets being in the barrel. I got one of the magnetic latches to hold the bolt open on a bench and that helps to catch the problem so I can take the mag out and single shot the first round but I would really like to find a solution to the problem. I have two Impact M3 and both do it to me, maybe I am too rough on stuff but it’s too late to change me now.

I had the same problem, I solved it by making a holder with a rare earth magnet in it which attaches to the link bar, so when you put the bolt handle into battery, you get a positive lock up, this can be varied by the magnet strength, I opted for a 1kg, which holds it nicely and since then i haven't managed to double load it.

I too use magnets to hold the bolt in position. Just bought some small, about .25" diameter, magnets and stacked a couple to make the bridge between the bolt linkage and the slide. Thye just pass over the bolt opening.
Issue resolved.

I have the Air marksman rail, it sort of holds the bolt open, not as positive has I would have liked, but better than FX offering.

Kevgun & Revoman- I would love to see photos of your magnet setups. I’ve had this same bolt flop issue.

If your cocking arm is popping open too easily, your probe block and seating depth isn’t adjusted properly. This is one of the first things you check when you take your new Impact out of the box. All 3 of my M3’s were out of whack and had to be degassed then partially disassembled to correct this before I even shot them.

I have a large cocking handle on my M3, thus, the extra weight made my bolt very susceptible to opening easily. I'll get you a picture of the remedy as it's super easy to do.

Pics as promised....package that the magnets come in (with price). Open package, I've used quite few for many other projects.
Bolt open and closed. These small diameter magnets just clear the bolt opening and 'stick' to the metal linkage within.

I thought the same thing, but mine as a barrel tension kit on it, which pulls the barrel support block forward, so by trying to solve one fault they have created another, the only proper cure would be to align it then drill and pin it with dowel pins so it can't move, the fault with the rifle is there are too many separate part which is causing tolerance stacking

I will take a photo later and post it up.

Very interesting and I agree.

Big thanks to Kevgun and Revoman for the magnet write ups and pics. It was just what the doctor ordered for keeping the bolt in battery when cocked.
I’ve also had issues with the bolt flopping forward when fully open and have had it push a projectile halfway in, such that the magazine could not be removed. I bought a Saber Tactical magnetic arm lock and have to say I’ve been underwhelmed. The face of the magnet doesn’t line up with the back the cocking arm, nor is it lined up such that the cocking arm will sit on top of the magnet. Instead, the only contact is bottom corner of the arm to top corner of the magnet and it doesn’t take much to push it forward. I’ve even rotated it a bit out of level to try to get more surface area contact but no soap. Nowhere near as secure as the ad- hoc magnet fix described above. Part is made in China but that doesn’t mean it shouldn’t align better.

Two hard rubber balls in the cocking block will keep the handle somewhat under "tension" when closed.
But I have the flat bar flipped around to allow more retract on probe.
