Things to consider about AR15 Stock
parts
Staking
the AR15 castle nut
This is a procedure to
ensure the castle nut does not unscrew. Debatable
since many people don't see this as necessary
Standard
vs. Heavy Buffer
The buffer is necessary for the
rifle to cycle. The size and weight of the buffer
can affect how the AR15 works. Changing buffers
can fix or cause problems
AR15 Standard Buffer
CAR / M4 / Carbine Buffer
Heavy Buffer
Hydraulic Recoil Buffer
9mm SMG Buffer
Mil-Spec
vs. Commercial Buffer Tube
Mil-Spec buffer tube is 1.148", Commercial
buffer tube diameter is 1.168"
Milspec is flat at the end, Commercial tubes
have a slanted end (longer)
AR-15
Cheek Rests
Some stocks (VLTOR,
LMT) offer cheek rests in their design, other options
are add-on cheek rests that wrap around standard
AR15 stocks.
AR15
recoil pads
Hardly needed
on most AR15s. Can be useful for adding length
to a short stock, rubber pads can also be useful
to keep a good shoulder weld on gear and body armor.
AR15
stock extenders
Not usually an issue with the AR15,
but these parts do exist.
