Control feed to push feed

[Mach2]

I have a old model 116 in 300 RUM controlled feed it is possible to change it to a push feed by installing a push feed bolt head? I have to remove the fixed ejector only?

There are probably several other subtle design aspects than just the bolt head that make up a push feed. Im sure you could do that though. May not feed like a dedicated push feed.
May be different extracters for instance. The mag follower may even be different. Dunno.
