The earliest rifles were shipped in the H-S Precision aluminum chassis fiberglass version of the Winchester Marksman stock.
FN Special Police Rifles of all iterations are noted for being both very accurate (0.5 MOA or somewhat less is not uncommon) and very low maintenance, featuring Parkerized metal finish, synthetic stocks, and a chrome-lined bore in the barrel.
A chrome-lined bore offers a more durable, more corrosion resistant, and easier-to-clean barrel for the end user to maintain and is rarely found on precision bolt-action sniper rifles.
The barrels of the "First Generation" rifles were said to be made from the hammer-forged blanks used for M240 General Purpose Machine Gun production at the FN Manufacturing Inc. plant in Columbia, South Carolina.
Later barrels are said to be from hammer-forged blanks intended exclusively for FN Special Police Rifle production.
