Developed in the 1910s, the Parker-Hiscock system converts a 303 caliber Enfield service rifle to a 22 caliber repeater suitable for both basic marksmanship practice and "rapid fire" on small bore ranges. The barrel is sized for 22, and the bolt reconfigured for rimfire. The true heart of the system is in the magazine which has a spring-loaded apparatus housed in the body of a conventional 303 magazine. The apparatus, numbered "G6613" or "613" on the components, integrates a single stack magazine, a push rod assembly, and a beveled top. When the bolt opens, the magazine pops up to align with the breech, and the closing bolt first drives the push rod to deliver a round to the breech and then the surfaces of the magazine and bolt interact to push the magazine back down into the housing. On follow-up shots, the magazine doubles as an ejector mechanism for the spent casings, physically pushing them out of the rifle when it pops up. While novel and mechanically intriguing, the Parker-Hiscock had a very short service life, being added to inventory in 1915 and declared obsolete in 1920. Standard blade and tangent sights are present, with the BSA logo on the barrel, "FTR 1954" on the receiver and "1955/.22 No 2" on the socket. Fitted with a smooth matching numbered stock.

Very good, with 80% of the arsenal refurbished black finish, with some sub-surface pitting, scattered handling marks and edge wear. The bolt is numbered to match, though the head lacks the appropriate bevel on the underside for bearing against the magazine during cycling, causing the mechanism to hang up. The stock is good, with a number of scuffs and dents. Aside from the prior note, mechanically good.

Dated "1944", with a set of "IAC" import marks on the receiver. Fixed blade front and folding ladder rear sights, with matching numbers on the bolt and magazine, and a smooth buttstock.

Very good, with 85% of the imported refurbished black paint finish, showing some light edge wear and handling marks. The stock is good, with a number of dings and scuffs. Mechanically very good.
