Wolverine MTW Retention Screw — Gen 3 Feed Tube

Wolverine moved the MTW to the Gen 3 feed tube in 2023, and the tube is held by a retention screw rather than friction. It is a small fastener doing a job that matters: if it backs off, the tube is free to shift under the engine, and the first sign is usually feeding that has gone unreliable for no obvious reason.

Screws this size vanish. They end up in carpet, in a parts tray that got tipped, or still in the old tube that went in the bin. Having a spare in the drawer is the difference between finishing a rebuild and stopping it.

This is the genuine Wolverine fastener for the Gen 3 tube, so the head and thread are the ones the receiver was cut for. Substituting a similar-looking screw from a tin is how threads get damaged in a part you cannot easily replace.

Specifications

Good to know before you buy

Check which feed tube generation your rifle runs before ordering. Wolverine introduced Gen 3 in 2023 and the correct version depends on when the upper was made, so an older rifle may be on an earlier tube entirely.

Worth adding to an order you are already placing. On a part at this price the postage is the expensive half, so it belongs alongside a bucking or a service kit rather than on its own.

Frequently asked questions

Which feed tube does this suit?
The Gen 3 tube. If yours is an earlier generation the retention arrangement is different — send us the rifle details and we will point you at the right part.

Is the feed tube included?
No, this is the screw on its own. The tube itself is a separate listing.

Can I use a generic screw instead?
We would not. The thread is cut into a part that is far more expensive than the fastener, and a close-enough screw is how that thread gets ruined.

How many do I get?
One screw. If you want a couple as spares, order the quantity you need.
