Hinderer XM-18 3.5" Lanyard Backspacer Copper

Manufacturer: Hinderer Knives

Model: HK-XM18-35-BACK-L-CU


Out of stock


Note: This item requires the HMBS Parts Kit for installation and won't work with factory installed standoffs. If you don't have one installed yet, start there to make sure everything is compatible before purchasing.

After years of waiting for a backspacer option Hinderer has finally come up with the HMBS (Hinderer Modular Backspacer System). This full copper backspacer features a lanyard attachment and is compatible with the XM-18 3.5" model. It can easily be swapped out for other backspacers using the pre-installed set screw, just make sure you have the HMBS kit installed first! Also comes with a matching front barrel spacer which can be installed with a bit more work.
