J&E Machine Tech AR-15 Polymer Vice Blocks Upper & Lower Combo

The J&E Machine Tech AR-15 Polymer Vice Block Combo is a purpose-built bench tool that makes AR-15 platform assembly, maintenance, and gunsmithing work safer and easier. This set pairs an upper receiver block with a lower receiver block, letting you securely clamp your rifle's components in a bench vise without crushing, marring, or distorting critical surfaces.

Constructed from heavy-duty polymer, the blocks are solvent resistant and shaped to seat standard AR-pattern upper and lower receivers. They deliver safe, non-damaging clamping pressure so you can torque barrel nuts, install handguards, service bolt carrier groups, or perform detail stripping on the lower with confidence that the finish and dimensions of your receiver stay protected.

Designed for use with AR-15, M16, and M4 pattern rifles and carbines, the combo is an essential bench companion for anyone building, tuning, or maintaining a black rifle. The polymer build keeps the set lightweight and easy to store, and it will not react with the harsh solvents commonly used in routine firearms cleaning.

Features:

• Safe and non-damaging clamping of AR-pattern upper and lower receivers
• Solvent-resistant polymer construction
• Fits AR-15 / M16 / M4 platform rifles and carbines
• Upper and lower blocks included in one combo
