Scalarworks BOR110 mounting plates that replaces the Benelli M4 factory rail. $90 The Decisive Trijicon RMR mount for Benelli tactical shotguns. Places your Trijicon RMR as low as it will go without obstructing your sight picture. Meticulously machined to be the lightest optic mounting solution for Benelli Tactical shotguns. Six MIL-STD-1913 slots for mounting Picatinny compatible accessories. Includes rail and 5 mounting screws.

Mount only. $90 shipped.

I have one on my M4; however, I have also opened up the port to expose the shell catch. This supports two-up speed loading.

Could sell the mount separately.

Type 1. I've had it mounted/shot on an M&P C.O.R.E. 9mm (about 6 months) then on the Benelli M4 (last year's 3-gun season). I had a Burris FF II on the M4 but that was not compatible with Scalar Works mount, so I swapped them. Never any issues. My eyes have just gotten too old for red dots. BTW. I may sell my M&P C.O.R.E Custom Shop with the Burris also.

Reasonable offer will be considered.

I have a Scalarworks RMR/Trijicon RM06 for sale. See my post.

Updated with better pics.

The M4 is a great gun, after you get the tube to hold 7, look up how to "ghost load" and you can load the gun with 9.

If removing the retainer does not solve your problem, cut the spring. To determine how much to cut, compare the length of the compressed spring (length of tube less length of 6 full shells and the portion of the 7th shell that fit into the tube and width of follower) and the length of the uncompressed spring. Now, determine the compression factor as Compressed Length/Uncompressed Length. Next, remove spring and cap. Insert, follower and seven shells. Measure down the cap end of the tube to the inside edge of the follower (where the spring will rest). This is the max space for the compressed spring. Finally, divide Max Space by the Compression factor to determine the Max Length of the uncompressed spring. Cut spring to length.

Yes, you can remove the retainer. Just remember when removing the cap that the spring is not retained.

I would cut the spring. They are often too long.

I have one of the original Scalarworks BOR110 mounting plates (with the rail) that replaces the Benelli M4 factory rail. This, with a Trijicon RMR, will co-witness with the factory sights. Trijicon RM06 has been sold. All screws included with mount. Mount only $90 shipped within continental US.

The fewer the notches, the tighter the choke. Four notches is an Improved Cylinder. This should be fine for 00 buck. Google "benelli choke markings" for more information.

The M4 is already a much lighter recoil than other shotguns.

I have the following available: 1) ATI Raven Mag Tube, +1 tube (with cap, spring and follower) Total retail $78, Sell $40 2) ATI Raven Mag Tube Picatinny Rail Shroud, 3 sided rail. Retail $75, Sell $40 Will sell you both for $80 shipped.

Bump. $100 takes it all.

High Speed Gear shotgun shell trays (2). These velcro to shotgun side plate to give you a removable/replaceable side saddle. New, never used. Asking $20 FTF NOVA or $25 shipped.

I have close to a thousand rounds through mine and not a hint of damage.

I see the "Mako" is now sold as the Fab Defense BM4. I have one for half price.

I have a Mako Quad Rail Forend - light internal modification to keep gas pistons from touching the forend; pistons now function perfectly. I also removed the bottom rail to improve the feel of the grip. Retail $80, Sell $40 (plus $5 to ship)

You will need a longer mag tube spring when you add an extension. Most extensions come with a longer spring. If you are only adding 1-2 shells, you may be able to get away with the stock spring.
