The Agency Arms rail is a pain in the dick to remove for servicing the ARGO system. If I recall it was like 12 torx screws had to be removed to get the bastard off. So if you do a Loctite regiment every time you back the screws out, you're really going to be hating life. The worst part is it doesn't really offer you a decent weapon light mounting position.

Junky aftermarket parts, junky ammo, what else would anyone expect? Not to mention the totally unnecessary "trying to look tactical" bashing on the damn thing. 👎

That’s the 1st thing thought when I saw all the other “quality work” they had done.

To be honest I slap my bolt release tab a lot because it’s…. Fun. Never had any problems with the OEM handguard and my bolt release being slapped to release the bolt. some differences are mine is 1075 spring steel at 45RC. Those other speed bars are 4140 at 30 Rockwell or so. Big difference in stiffness.

Well said as always Stranger! The BM4 is a quality firearm..and firearms are often referred to as a tool. I never have nor will understand why so many people are incapable of due diligence/homework that is so easily accessible today to establish what is cheap-gucci-crap to avoid because it may fail/compromise their firearm..vs. what is known to be a quality replacement part that provides a purposeful upgrade. Good lord that Speed Bar abuse test??..pure ignorance..next that dude will torture test the Briley mag tube with a hammer or Map torch until failure. Agree about Strike Industries..a strip-center beauty salon for dressing up firearms with you know..essential style.

Agreed. My dad had one. It was my first Benelli to learn on.

Singuardsolutions.com did mine and I couldn't be happier. I went with the nanoburst texture. Very quick turnaround too.

500 rounds really isn't even much of a test. The half assed installation of the aftermarket components likely caused all of their grief. Unless you're really chasing weight savings, get a Carriercomp magazine tube over the Briley. Briley dicked around when they made their tubes so that each end of the tube is seated into a stainless end which has the threaded ends. The trouble is, the transition from stainless to carbon fiber tube is not the best. Inserting rounds, the follower can hit the transition and stick even with their aftermarket follower that is designed to work around that exact issue. That's exactly the issue they were having where they were struggling to load rounds and having to hold your mouth just right to get it to pass over the transition. You can play warranty games with Briley, but it's going to take a bit to fix everything right. You don't have any of those issues with a single piece titanium or steel tube. Whatever you get, put some thread locker on it. Strike Industries is synonymous with crap. Set screws to keep the rail from rocking back and forth that press against your handguard retainer and barrel casting is a piss poor design. All that movement can lead to a piston striking the rail. That Speed Bar wasn't going to last long with those Mongo's beating on it like that. That's a light duty part at best. Even a GG&G would probably end up breaking from that kind of abuse. We've all seen the size of the screw that holds that pad in place. I think they alluded to replacing the receiver extension? That's the area I'd be concerned with.

Great shotgun, unfortunately spare parts (such as wooden buttstock or aftermarket synthetic buttstocks) are non-existent. Benelli quit making the 121M1 like 35 years ago.

Yep.. exact same setup I run. I also swapped out my 3pos OEM recoil tube for a 6pos RXARMs tube. That #4 position is a game changer.

I run rx arms titanium charging handles .comp carrier titanium tubes ..And tryed aftermarket handguards.a they just make a heavy gun even heavier.And suck when you have to breakdown to clean it .So I switched back to factory stippled handguards.And I use scalarworks with t2s

Aftermarket stuff. Stick with OEM.
