It has taken the engineering excellence of Ed Brown
Custom to finally successfully blend the advantages of
both push feed and conventional controlled feed into
one new action - the Model 704. It's a design never
before seen on a bolt action rifle. Completely
controlled feed, but without the disadvantages of the
long extractor Mauser/Winchester design. Retaining
100% barrel threads, and complete receiver integrity,
this design offers genuine controlled feed
reliability. Plus, it still has a counterbored chamber
with the bolt partially surrounded by bolt face steel.
Our spring loaded extractor is integral with the bolt,
and rotates with it, to position the extractor under
the cartridge for full support inside the chamber,
thus placing the bullet in a perfect position for it’s
exit.

Since the age of the 1898 Mauser, there has been a
demand for the controlled feed action. Winchester has
possibly done more than anyone to promote the
advantage of the controlled feed design. When hunting
dangerous game, where feeding could be a life or death
situation, the controlled feed design has become the
choice of many professional hunters.

Of course, dangerous game guns have never required a
high degree of accuracy. One does not need a half MOA
accurate 458 for stopping a charging Buffalo at fifty
yards..

Much like reliability has been the realm of the
Mauser/Winchester controlled feed action, accuracy has
been the forte of the Remington push feed design. One
finds the Remington push feed design to be the choice
of benchrest shooters worldwide. This is due to their
extreme accuracy inherent in the round receiver push
feed design.

A Mauser/Winchester type controlled feed long
extractor requires the removal of a large portion of
the barrel threads where the extractor must go.
Removing barrel threads is not the way to the most
rigid assembly. This larger receiver cut also removes
precious metal inside the receiver which is
detrimental to the rigidity, and thus the accuracy of
the entire assembly.

The M-704 has 100% uninterrupted barrel threads in a
round receiver, for maximum rigidity and strength. Yet
our massive steel extractor allows for true controlled
feeding. Our new M-704 design couples the best designs
of both worlds, while eliminating the problem areas.
It's our finest accomplishment yet.

That's an interesting idea. I can't quite believe they're the first ones to try it.

My little experience with Brown rifles hasn't impressed me. But I haven't seen enough of them to give them a fair chance.

Face of the bolt looks alot like the Savage 116 African model and the Winchester varmit rig a buddy showed me
