4.4 Lubricants and Cleaners

e M6 Series is compatible with all standard U.S. Military and NATO speciﬁed small arms

lubricants and cleaners. e manufacturer recommends SLIP 2000 EWL (extreme Weapons

Lubricant for 1.0 oz tube). If changing from one lubricant to another clean oﬀ old lubricant

by scrubbing parts with solvent, Simple Green or SLIP 2000 Carbon Killer.

Lubrication Terms:

Light Coat- A light coat of lubricant is not readily visible to the eye. Apply lubricant and wipe

oﬀ excess with a clean cloth.

Moderate Coat- A moderate coat of lubricant should be just visible to the eye. Apply lubricant

directly to part and spread or apply with a brush, cloth or ﬁnger.

Point Lubrication- Lubrication applied to pivot points or recessed parts. Apply a couple of

drops to the pivot point and work part back and forth to distribute lubricant.

4.5 Rail Maintenance and Notes

1. ere is no required rail maintenance other than protecting the Picatinny rail

sections that remain exposed to damage with a rail or ladder panel. e ARM-R

rails are set up to use USGI issue rail panels by Knight’s Manufacturing. Any

Picatinny 1913 standard rail panel will work.

2. e 4 rail retaining screws are factory torqued to 40 inch pounds. e Heli-coils

in the rail clamp have a locking feature that prevents these screws from loosening

oﬀ. It is not advised that you remove the screws unless you have signiﬁcant reason

to do so. If you do remove them, install the rail ensuring the picatinny rail on the

rail clamp is butted up and aligns perfectly with the picatinny rail on the receiver.

Apply red Loc-Tite to the degreased screws. Install tightening each screw ﬁnger

tight then use a 9/64th’s Allen wrench, and make one turn to each screw in a cross-

hatch pattern until 40 inch pounds is reached. ere should be no gaps between

the rail clamp legs and the lower assembly of the rail system.

3. ere are small C-Clips that make the pusher screw captive. In the rare event this

becomes dislodged or lost, a standard C-Clip for an M16 ejection port rod can be

used. With the top rail removed, screw in the pusher screw all the way. With

needle nose pliers, install the C-Clip to the groove toward the nose of the pusher

screw.

4. During normal use, the rail will become fouled with carbon and some copper

residue from jacketed ammunition. If left to sit the copper will turn a blue/green

color. is nothing to be concerned with. You can remove with a copper solvent.

You should always inspect the inside of the top rail to ensure the fouling does not

interfere with piston operation.
