6.9 RAIL MAINTENANCE AND NOTES
The R.E.P.R. features a free oated user congurable rail system. The
rail does not come into contact with any part of the barrel allowing
the use of accessories, a bipod or the rail itself as a support surface
without aecting the point of impact of the bullet. The rail has a
monolithic prole 12 o’clock rail that perfectly mates to the rail on
the upper receiver allowing the stacking of sighting devices. The 3,
6, and 9 o’clock rail sections are user congurable. You can install
one of several available rail sections to any portion of the rail tube
dependant on where you usually mount your accessories. This was
done to cut the weight of the rie, and make the user interface with
the system more comfortable.
6.9.1 There is no required rail maintenance other than protecting
the M1913 Picatinny rail sections that remain exposed to damage
with a rail or ladder panel. The R.E.P.R. rails can be set up for use
with LWRCI Rail Skinz or USGI issue rail panels. Any Picatinny 1913
standard rail panel will work.
6.9.2 There are several congurations of rails and sling adapter
rail sections available. Please see the LWRCI Web-Store to order
additional rail sections, lengths and congurations. To install a rail
section, use the supplied Allen head machine screws (they have
pre-applied thread-locker already applied and are not standard
machine screws). Match the installation holes on the rail section to
the appropriate holes in the rail system. Install the screws using a
5/64” Allen wrench to no more than 15 inch/lbs. If you remove the
Allen head screw to reposition a rail section, ensure you degrease the
screw and the hole with a suitable degreasing solution (e.g. alcohol,
acetone etc.). Apply blue Lock-Tite or suitable medium-strength
thread locker to the screw before installation.
6.9.3 The barrel nut of the R.E.P.R. also acts as the rail mount. It is
not recommended you remove the rail of the R.E.P.R. as there is no
requirement to do so at the operator level.
6.9.4 There 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.
6.9.5 During normal use, the rail will become fouled with carbon
and some copper residue from jacketed ammunition. If left, the
copper will turn a blue/green color. This is purely cosmetic and will
not adversely aect the weapon. You can remove it with a copper
solvent. You should always inspect the inside of the top rail to ensure
the fouling does not interfere with piston operation. Some wear on
the inside of the Top Rail is normal.
