Bore Tech Receiver Wiper Set
Two shaped cleaning wipers for barrel extension and upper receiver – platform-specific for AR-15/M16 or AR-10.



Two shapes, two tasks The cross-shaped wiper works behind the locking lugs in the barrel extension. The round wiper presses the patch against the inner wall of the upper receiver.


What else is needed A non-rotating rod with female 8/32 fitting, matching round patches, and cleaning solvent. The set is not a complete receiver kit.


Why the shape is better than an improvised swab
The flexible fingers of the barrel-extension wiper compress when passing through the locking lugs and open again behind them. The round upper wiper uses the inner contour of the receiver. This guides a patch more precisely to hard-to-reach surfaces than loose cloth or cotton swabs.


Variants: AR-15/M16 and AR-10 – do not treat as interchangeable sizes.

Patch size according to Bore Tech: approx. 2.5 inches round for AR-15; 2.75 inches round for AR-10.

Thread: both wipers with male 8/32.

Rod: non-rotating version with female 8/32 counterpart, because cleaning works with controlled rotational movement.

Material: molded, solvent-resistant rubber with Proof-Positive core.


Buy if … you already have rod, patches, and solvent and want to clean the barrel extension and upper receiver of an AR-15/M16 or AR-10 specifically.

Don’t buy if … you expect a complete kit, tools for bolt/bolt carrier, a barrel cleaning set, or a universal solution for other platforms.
Workflow without pushing material

Safely unload the firearm and disassemble according to the manufacturer’s instructions.
Check platform variant: AR-15/M16 or AR-10.
Choose cross wiper for barrel extension, round wiper for upper receiver.
Center a matching round patch and moisten sparingly with suitable cleaner; Bore Tech names among others C4 Carbon Remover.
Work with light pressure and controlled rotational/pulling motion; do not force if there is strong resistance.
Replace with fresh patches and finish with dry patches.

If the entire receiver basic equipment is missing, the re
ceiver Cleaning Kit the more honest choice. For narrow recesses, a polymer cleaning tool can complement. Barrel cleaning remains a separate tool strand.

Practical/Instructor Tip: Let the two wipes first be assigned dry to the respective area. When participants understand shape, patch size, and direction of movement before cleaner comes into play, the risk of making a wrong wipe "fit" with additional force decreases.

Important limit: A saturated patch eventually only transports dissolved dirt further. Loosen damp, change patch, check dry – instead of working the entire receiver with a single patch.
