Rossi Brawler Handguards

The factory forend on a Rossi Brawler gives you a place to hold the gun and nowhere to mount anything. These drop-in Nylon-12 handguards go on in its place at the factory mounting, reuse the factory screws, and add M-LOK slots on both sides plus a mount on the bottom. That gives you room for a light, a laser, a sling mount, a hand stop or a tripod clamp, with no drilling, and the factory forend goes back on whenever you want it.

All three fit the Rossi Brawler in 5.56 and 300 Blackout, and they differ by what sits on the bottom: a 2 in. (51 mm) Picatinny rail, a single M-LOK slot, or an ARCA rail that clamps to a tripod and has one M-LOK slot in it. The Picatinny version is 3.45 in. (87.6 mm) long and the M-LOK version 3.25 in. (82.6 mm), both with two M-LOK slots per side, and the ARCA version runs 5.25 in. (133 mm) with three per side. All three are about 1.5 in. (38 mm) wide, with textured side panels.

Whichever one you pick, it installs the same way and comes back off with no permanent change to the gun. Choose the bottom mount that matches the accessory you want under your support hand, then check whether you want the extra length and side slots of the ARCA version.

The lineup

Where it shines

  1. You keep the Brawler by the back door for the coyotes that come after your chickens. With a light on the bottom rail, you can see what you're looking at before you decide anything.

  2. You already own a Picatinny light and a laser from another build. Clamp them onto the bottom rail and the Brawler is set up with nothing new to buy.

  3. You carry the Brawler on a sling at the range. A QD sling point in a side M-LOK slot keeps the bottom rail free for your light.

  4. You want the upgrade but might sell the Brawler one day. Because the handguard uses the factory mounting with no drilling, you can put the stock forend back on and the gun is as it came.

  5. You're running drills at the range and your support hand keeps creeping forward. Put a hand stop on the bottom slot and you'll find the same grip every time you bring the Brawler up, with nothing else in the way.

  6. Your Brawler rides behind the truck seat, and you want a light on it for checking the barn after dark. Mount the light on a side slot and keep the bottom slot free for your hand.

The Guide

Choose the Bottom Mount

The bottom of the handguard is the main difference between the three, and it sits right under your support hand. A Picatinny rail takes the clamp-on lights, lasers and hand stops you may already own. A single M-LOK slot keeps the front end the lightest of the three, for a one-slot hand stop or an M-LOK bipod adapter. An ARCA rail clamps straight into an ARCA tripod head or quick-release, so the gun sits locked in place so you can glass without holding the gun. It also has one M-LOK slot in the rail. If you already run Picatinny gear, choose Picatinny; if your accessories are M-LOK, choose M-LOK; and if you plan to shoot off a tripod, choose ARCA.

  • Picatinny: 2 in. (51 mm) rail for clamp-on Picatinny accessories
  • M-LOK: one bottom slot for one-slot M-LOK accessories, the lightest at 2.15 oz (61 g)
  • ARCA: tripod head, quick-release and ARCA bipod clamps, plus one M-LOK slot in the rail

Match the Length and Side Slots

Length sets how much room your support hand gets and how many side slots you have to work with. The Picatinny version is 3.45 in. (87.6 mm) and the M-LOK version is the shortest at 3.25 in. (82.6 mm), both with two M-LOK slots per side, which keeps the Brawler compact. The ARCA version is 5.25 in. (133 mm) with three slots per side, enough for a light on one side and a sling mount on the other with room to spare. All three are about 1.5 in. (38 mm) wide. If you want the shortest front end, choose the M-LOK version; if you want more hand room and side slots, choose the ARCA version.

  • Picatinny: 3.45 in. (87.6 mm), two M-LOK slots per side, 3.4 oz (95 g)
  • M-LOK: 3.25 in. (82.6 mm), two M-LOK slots per side, 2.15 oz (61 g)
  • ARCA: 5.25 in. (133 mm), three M-LOK slots per side, 2.8 oz (80 g)

Check Before You Order

All three handguards fit the Rossi Brawler in 5.56 and 300 Blackout, and they install the same way: each drops in at the factory mounting and reuses the factory screws. Your accessories mount with their own M-LOK or rail hardware. An ARCA rail needs an ARCA clamp on your tripod head, so check what your head uses if you're buying for tripod work. Before you order, confirm your chambering, make sure your tripod takes an ARCA clamp if you want ARCA, and keep the factory forend somewhere safe in case you want it back.

Field manual

How do I choose between these handguards?

Start with the bottom mount, since that's the main difference and it sits right under your support hand. Choose Picatinny for clamp-on accessories you already own, M-LOK for the lightest front end, or ARCA for a tripod. Then look at length, because the ARCA version is longer and has an extra M-LOK slot on each side. All three fit the same guns and install the same way, so nothing else should steer the choice.

Which Brawler models do they fit?

All three handguards fit the Rossi Brawler in 5.56 and 300 Blackout. They're made for the Brawler only and won't fit other firearms. If your Brawler is in another chambering, contact us before you order and we'll tell you what we know. Check your Brawler's chambering on the barrel or in the owner's manual if you're not sure which one you have.

What's the difference between the Picatinny and M-LOK versions?

Both have two M-LOK slots and a textured panel on each side. The main difference is the bottom. The Picatinny version has a 2 in. (51 mm) Picatinny rail for clamp-on lights, lasers and hand stops, measures 3.45 in. (87.6 mm) and weighs 3.4 oz (95 g). The M-LOK version has a single M-LOK slot on the bottom, measures 3.25 in. (82.6 mm) and weighs 2.15 oz (61 g), so it's the shortest and lightest of the three. Choose Picatinny if your gear is Picatinny, and M-LOK if your gear is M-LOK and you want the shortest, lightest option.

What is an ARCA rail, and do I need one?

ARCA is a dovetail rail standard for tripod clamps and quick-releases. The rail on the ARCA version is ARCA-Swiss compatible, so it slides into a standard ARCA clamp and locks when you tighten it, with no plate or adapter in between. ARCA bipod clamps attach the same way. If you don't plan to shoot off a tripod or an ARCA bipod, you don't need one, and the Picatinny or M-LOK version will serve you better.

Can I run a tripod and a light at the same time?

Yes, on the ARCA version. It has the ARCA rail on the bottom for the clamp and three M-LOK slots on each side, so a light goes on a side while the gun sits on the tripod. Check that your side accessories clear your ARCA clamp before you tighten them down. The ARCA rail also has one M-LOK slot, but the clamp covers it, so a one-slot accessory there means no tripod clamp at the same time. The Picatinny and M-LOK versions have no ARCA rail, so their bottom mount is for a light, a laser or a hand stop rather than a tripod clamp.

What can I mount on them?

The side M-LOK slots take standard M-LOK accessories such as a light, a sling mount or a hand stop. What goes on the bottom depends on the version: clamp-on Picatinny accessories on the Picatinny rail, a one-slot M-LOK accessory on the M-LOK version, or a tripod or bipod clamp on the ARCA rail, which also has one M-LOK slot for a one-slot accessory when no clamp is on it. Mount each accessory with the hardware it comes with and tighten it to its maker's spec. Plan your layout before you tighten everything down, since the handguard is also where your support hand rides.

What hardware is included, and can I go back to the factory forend?

No hardware is included, because none is needed. Each handguard is a drop-in part that goes on in place of the factory forend, at the factory mounting, using the factory screws. Remove the factory forend, set the handguard in its place and secure it with the same screws. There's no drilling, cutting or fitting, and you should check that everything is still tight after your first range session. The install video on each handguard's page applies to all three versions, since they mount the same way. Every swap is fully reversible: keep your factory forend, and it goes back on the same way the handguard came off.

What are they made of, and what's the warranty?

All three handguards are made from Nylon-12, which doesn't rust and needs no finish touched up after a wet day in the field. Wipe them down with a clean cloth after a range session to clear off dirt and carbon. Each one is made in Coopersville, Michigan, and covered by our Limited Lifetime warranty. If something isn't right with your handguard, contact us about a warranty claim.
