                                         Unlocking
                                         As the bullet travels down the barrel and passes the gas port, the propellant gases behind the bullet are
                                         siphoned off by the gas port. This gas travels through the gas block before flowing down the gas tube and
                                         into the nozzle on the carrier. The pressurized gas forces the carrier to start moving backwards. As the bolt
                                         carrier group moves in the upper receiver, the cam pin follows the path of the cam pin track in the upper
                                         receiver which, in conjunction with the gas working against the gas rings of the bolt, causes the bolt lugs
                                         unlock from the barrel extension. The rearward motion of the bolt carrier group is called the recoil stroke.
                                         Extraction
                                         As the bolt carrier group continues its recoil stroke, the extractor (the part of the bolt that grips the rim of
                                         the cartridge case) holds firmly to the cartridge, causing the empty cartridge to be withdrawn, or extracted,
                                         from the chamber.
                                         Ejection
                                         Once the empty cartridge is withdrawn to the ejection port, it is flung from the weapon by the spring loaded
                                         ejector, located on the bolt face.

                                                     Cocking
                                                     In semi-automatic firing, as the bolt carrier recoils to the rear, it cocks the hammer. The hammer is initially
                                                     retained by the disconnector. As the shooter lets go of the trigger, the disconnector releases the hammer.
                                                     The hammer moves slightly before re-engaging the front face of the trigger. This re-engagement is called
                                                     the reset.
                                                     In automatic firing, as the bolt carrier recoils to the rear, it cocks the hammer on the auto sear. As the
                                                     carrier moves back forward after it has completed its recoil stroke, the front of the bolt will trip the auto
                                                     sear, releasing the hammer and firing the round. When the shooter releases the trigger, the hammer is
                                                     caught by the hammer/trigger engagement surface and the fire control group is reset.
                                                     Feeding
                                                     The recoil stroke concludes when the buffer halts the rearward motions of the bolt carrier group. The buffer
                                                     spring, which was compressed during the recoil stroke, drives the bolt carrier group forward. This forward
                                                     motion is called the counter-recoil or return stroke. As the bolt carrier moves forward, the next round is
                                                     stripped from the top of the magazine and directed into the chamber by the magazine feed lips and the
                                                     receiver feed ramps.
                                                     Chambering
                                                     As the bolt carrier group continues the return stroke, the round is seated in the chamber.
                                                     Locking
                                                     The bolt carrier group completes the forward motion of the return stroke, the bolt locking lugs pass between
                                                     the barrel extension lugs. During the last ½” of bolt carrier group travel, the cam pin moves from the guide
                                                     channel into the cam pin recess, rotating the bolt counter-clockwise and locking the bolt lugs against the
                                                     barrel extension lugs.

                       Note that the use of water-based lubricants, such as WD-40, is not advised as the
                       water content of the lubricant can actually aid corrosion.
                       When applying lubricant, use a moderate coat of lubricant on moving parts. A moderate
                       coat should be just visible to the eye. Apply lubricant directly to the part and spread it

                    To complete the field strip of the lower receiver assembly, remove the buffer and spring from
                    the buffer tube:
                    1. With the hammer cocked, depress the buffer retainer using a screwdriver, punch, or other
                       suitable tool. The buffer should spring free. FIG 5.2.D

1. Pull the charging handle to the rear about three-quarters of the way.
2. Remove the bolt carrier group from the upper receiver. FIG 5.2.F
                    3. Pull the charging handle fully towards the rear. Remove the charging handle by moving it
                       downward so the expanded end of the charging handle passes through the cut-out in the

                                    5.3 DETAILED DISASSEMBLY
                                    Detailed disassembly is simply breaking down the rifle as much as is possible without specialized tools.
                                    This type of disassembly should be done routinely. For example, the detailed disassembly might be done
                                    after several thousand rounds of suppressed fire or before the rifle is put away for extended storage.
                                    To complete the detailed disassembly of the lower receiver, simply remove the stock:
                                    1. Grasp the adjustment lever on the underside of the buttstock. Pull the adjustment lever
                                       straight down to disengage the stock pin, and then slide the stock off of the end of the buffer tube.
          
                                    1. Cup the bolt carrier group in one hand and, with a suitable punch or the tip of a cartridge,
                                        push out the firing pin retainer in to your cupped hand. Do not twist the retainer during
                                        removal. FIG 5.3.A
                                    2. Slide the firing pin out of the rear of the carrier. FIG 5.3.B
                                    3. Rotate the cam pin to the side so that it is clear of the gas nozzle. Lift the cam pin out of the bolt
                                       carrier group. FIG 5.3.C
                                    4. Remove the bolt from the front of the bolt carrier. FIG 5.3 D
                            5.3.C
                                                                         5.3.D

                                                   5.4 REASSEMBLY
                                                   Reassembly of the LWRCI-DI is achieved by reversing the order of the disassembly steps. Some items to
                                                   keep in mind during the reassembly are:
                                                   1. When reinstalling the buffer and buffer spring, push the buffer fully into the buffer tube, passing the
                                                      buffer detent to ensure that it is fully captured by the detent.
                                                   2. Do not forget the cam pin. The rifle may chamber a round and fire without the cam pin, but that shot
                                                      could lead to catastrophic failure of the weapon.
                                                   3. Some degree of looseness of fit between the upper and lower receiver may be present. While this is
                                                      normal and has no effect on the function of the rifle, LWRC-DI’s are equipped with a nylon-tipped
                                                      tension screw which may be adjusted to address the looseness. The tension screw is located inside
                                                      the lower’s fire control group pocket positioned beneath the upper’s rear take-down lug.
