Luth-AR AR-15 A2 Stock Spacer – Aluminum, Black (A2S-01)

Dial in the classic A2 fixed-stock fit with the Luth-AR AR-15 A2 Stock Spacer (A2S-01). Precision-machined from aluminum and finished in black, this spacer installs behind your A2 buttstock to ensure correct overall length and proper interface with a rifle-length receiver extension (buffer tube). Whether you’re converting from A1 to A2 length, refreshing a well-used service stock, or bringing an aftermarket A2-pattern stock up to spec, the Luth-AR A2 spacer delivers the alignment, support, and durability your rifle deserves.

Why Choose the Luth-AR A2 Stock Spacer

• Corrects A2 Geometry: Provides the proper stand-off needed for A2-length stocks on rifle-length receiver extensions—no wobble, rattles, or misalignment.

• Precision Aluminum: Machined aluminum body resists compression, cracking, and deformation for long service life compared to plastic substitutes.

• Clean Black Finish: Low-glare finish blends with receivers and buttstocks for an OEM look on duty, competition, or retro builds.

• Consistent Trigger Reach: Restores intended length of pull (LOP) and cheek weld on A2-pattern stocks for repeatable shoulder mount and sight alignment.

• Drop-In Simplicity: Straightforward installation with basic armorer tools; pairs with the correct A2 buttstock screw and rifle-length receiver extension.
