The Benelli M4 is a shotgun I respect and trust. And I’ve been working with the diehard scattergun a lot, lately. Today I’m back with another overhaul that addresses what almost everyone acknowledges as one the gun’s biggest shortcomings.

I’ve already addressed the undersized controls and limited capacity. Now it is time to give this workhorse the final touch in the transformation: that old fixed stock has to go. I’ve already tested one of the leading aftermarket stocks sets, the ATI Raven. Today, though, we’re looking at the underdog.

ProMag is a company we are all familiar with; they’ve been making aftermarket extras for years. One such offering is their furniture package for the Benelli M4: a pistol grip, a railed forend, and a nearly identical copy of the Benelli collapsible stock. The ProMag furniture seemed to be too good to be true. It retails at MidwayUSA for $125, a note worthy $125 less than the going rate of a NOS M4 stock and it gives you the forend as a bonus.

Construction is more than adequate. The parts look just as good as the competition. Comprised of aluminum and glass filled impact resistant polymer, the stock is tough, and just as strong as the original Benelli furniture. The only noticeable difference on the furniture is the addition of polymer rail sections on the forend and a ProMag stamp on the heel of the pistol grip.

In use, the furniture adds utility to the firearm giving the forend mounting surfaces to accommodate lights, lasers, and vertical grips. The pistol grip and butt stock add comfort, and are adjustable, which allows the user the option of varied lengths of pull. When the gun is in storage, the stock collapses away, shortening up the overall length by nearly 6 inches. It is still fully functional and quick into action. The 3-position stock is compact enough for those wearing plate carriers.

The Benelli M4 is a platform that is formidable in its stock configuration. Adding a simple upgrade like the Pro Mag furniture set makes the gun even better. And the price of the ProMag stock makes this the single best Benelli mod available.

While it doesn't make the gun much more compact, the stock does allow for a more custom fit.

    Definitely sounds like a promising assortment of mods given the price. Great review!

    Where can you get a round bolt handle like that shown in the picture?

    • Larry March 2, 2015, 12:00 pm

      GG&G sells the charging handle for the Benelli M4. Also they sell a larger bolt release pad. It works great…

        Thanks for the tip on the larger bolt release pad. Do you recall what they run and how difficult it was to install ? Last time I looked into them I looked like I would need to do some machining on my M4 and was too excited about do that !

          Hello Brain, to tell you the truth I had a gun smith do the work for me. I can tell you this, he did not do any alteration to my M4. I had a lot of different work done to it. Tube extension, trigger, bolt release, follower, new spring. To safe me time I had him do the work for me. Hope this helped.
