The Panzer Arms M4 Speed Pro 12 gauge is the competition-style version of Panzer’s M4 semi-automatic shotgun, with a ported barrel, metal forend and skeleton stock (Panzer Arms part no. PAM4CSSFCTMFSS). Panzer Arms gives the Speed Pro a lightened bolt for rapid follow-up shots and ports the 18.5-inch barrel to reduce felt recoil and muzzle rise. The Pro designation means a metal M-LOK handguard rather than the polymer forend on the standard M4 Speed. An oversized knurled rotating charging handle, an oversized bolt release and a QD sling mount round out the controls. It suits 3-gun style shooting and home defense alike, wherever fast, flat follow-ups count.

Frequently Asked Questions

What is the difference between the M4 Speed Pro and the M4 Speed? Panzer Arms fits the Speed Pro with a metal M-LOK forend; the standard M4 Speed has a polymer forend. Both share the skeleton stock, lightened bolt and oversized ambidextrous controls.

Why is the barrel ported? The 18.5-inch barrel is ported to reduce felt recoil and muzzle rise, which helps keep the gun on target for follow-up shots.

Can left-handed shooters run it? Yes. The oversized knurled charging handle is ambidextrous, so it can be set up for left-handed operation.
