INTRODUCTION of the Remington Ny-
Ion 66 cal. .22 semi-automatic rifle
in 1959 heralded a new concept in firearms.
Featuring a one-piece stock, receiver,
and fore-end produced from
structural nylon, this unusual blowbackoperated
rifle was designed by a team
of Remington engineers headed by
Wayne E. Leek. The designation Nylon
66 was taken from the name of the highstrength
DuPont nylon selected for the
rifle.
Chambered for .22 long-rifle rimfire
regular or high-speed cartridges, this
rifle has a 14-round tubular magazine in
the buttstock. Due to the unusual construction,
troublesome fitting of stock to
receiver is eliminated. Another highly
favorable feature is that the nylon is extremely
strong and does not warp. Also,
the self-lubricating properties of nylon
make the need for oiling the rifle unnecessary
except to prevent rusting of
steel parts. This reduction in amount of
lubricant helps prevent sluggishness in
cold weather and slows accumulation of
fouling in the mechanism.
Weight of this reliably functioning
rifle is only 4Y4 Ibs., and handling
qualities are excellent. Accuracy is very
good for a semi-automatic rifle, especially
considering the lightness of the
arm.
The lightweight barrel of 190/8 " length
is fitted with a square-top front sight of
ramp type. A fully adjustable square.
notch rear sight is fastened to the receiver
cover assembly. Lengthwise
grooves on top of the receiver cover permit
easy attachment of standard clampon
telescope sight mounts.
In addition to the stock assembly, the
bolt handle, safety, trigger, trigger
guard, and several other parts are nylon.
The barrel, breechbolt, receiver cover
assembly, striker, springs, and various
small components are steel. When first
introduced, this rifle was offered with
choice of Mohawk Brown or Seneca
Green stock. Seneca Green was later
dropped, and Apache Black was added.
The version with Apache Black stock
has a chrome-plated barrel and receiver
cover. These parts on other Nylon 66
rifles are blued. .
1 Before disassembly, make sure rifle
is unloaded. Engage safety (36) on
safe position to rear. Pull bolt handle
(8) rearward, and check barrel chamber
through open ejection port. Colored magazine
follower should be visible. With action
cocked, grasp bolt handle firmly and
pull to right from rifle.
2 Unscrew and remove the two cover
screws (14). Lift receiver cover assembly
(34) from stock assembly (46).
Replace bolt handle into hole in bolt (1)
until handle is retained by pressure of
action spring plunger (2),
3 loosen barrel lock screw (6) until
barrel bracket (4) can be moved upward
in stock assembly far enough to
clear slot in top of barrel (3). Pull barrel
forward from stock assembly.
4 Remove ejector (19) from recess in
left side of stock assembly. Remove
barrel lock screw, barrel bracket, and barrel
support (5) from stock assembly.
5 Remove bolt handle. Push bolt forward
and remove from stock assembly.
Action spring (1) and action spring
plunger (2) are also disassembled from
rifle at this time.
6 Push safety forward to fire position.
Take care not to touch trigger (48)
since firing pin striker (27) is under compressed
load of firing pin striker spring
(28). Hold cocked striker against pressure
of spring, pull trigger, and ease striker
forward until spring tension is relieved.
Remove striker, spring, and striker spring
sleeve (47). Drive out trigger guard assembly
pin (51), and pull trigger guard
(50) from stock assembly. This is sufficient
disassembly for normal cleaning.
7 Reassemble in reverse. Place striker
spring sleeve (with flanged end rearward)
into hole in stock assembly. Replace
spring over sleeve. Slide striker
rearward along bolt rails in stock assembly
until spring enters hole in rear of
striker and rearward motion of striker is
stopped by sear (43). Pull trigger. Push
downward on front end of sear and move
striker rearward over sear until cocked.
Release trigger. Sear will hold striker
cocked in rearward position. When reassembling
receiver cover assembly to
stock assembly. cartridge feed guide (9).
