In May 1990, Air Arms sales and marketing manager Bill Sanders revealed to airgun world that over the previous few months a 10m version of the 100 series had been in development, with advice from top 10m shooters being sought at the design stage. Initial prototypes were looking very promising and Bill was confident that the final result would be a 10m rifle capable of competing with the best of the foreign guns available, particularly in the lucrative German market.
Colin King was in charge of the action design and Nick Jenkinson was responsible for the design of the stock.
The rifle was later named the RN10 – the “RN” in the name are Air Arms owner Robert (Bob) Nicholls’s initials and the 10 is due to the 10m nature of the rifle.
In 1991 the RN10 was on show at the 18th International Trade Fair for Hunting and Sporting Arms in Nuremburg. There was reportedly strong interest from German and Swiss buyers.
Airgun World June 1991
Around the end of 1991, possible early 1992, the RN10 was marketed in Europe in conjunction with RWS as the CA100.
Airgun Wolrld October 1992
In the UK the RN10 was available on a “made to order” basis. Sales in Europe and the UK were disappointing, leaving air arms with a substantial amount of rifles and parts on their hands.
Potential for field target use had already been identified by Nick jJenkinson, who had been successfully using his custom 12fpe version. With the assistance of Nick, prototypes were produced and passed to the likes of Terry Doe, Ken Turner and Richard North to provide feedback.
The stock design and general ergonomics were good for FT shooting and it was found to be relatively straight forward to increase the power. A slightly stronger stroke and higher regulator setting gave good results. The standard striker spring gave plenty of adjustment and the firing cycle was not compromised. A good shot count of 90 plus shots from a 200 bar fill was achievable.
As early as October 1993 Link Arms, Nick Jenkinson's company, was taking deposits for the soon to be released RN10.
The final stages of development and readiness for full production took significantly longer than expected and it was not until late 1994 that the FT version of thje RN10 was with retailers.
Advert Form November 1994
Reliability issues were identified with the early regulators, which were finally resolved with the introduction of the Mk3 regulator, which was designed by Joe Korick, who consulted other experts, such as Dave Welham.
Over time many of the early RN10’s/Pro-Targets were returned to Air Arms to have their regulators updated to the Mk3 version. This happened to such an extent that very few rifles can be found with Mk1 or 2 regulators still fitted.
Around the same time as the Mk3 regulator being introduced the name Pro-Target started to be used in favour of RN10 and the Pro-Target Tactical Hunter was launched.
Advert From 1998
Although the FT version had 3 distinctive versions over the years – Mk’s 1,2 & 3– the original 10m version only had minor cosmetic changes and a name change to “Pro-Target 10m”.
After a disappointing start in life as a 10m rifle, the RN10/Pro-Target FT was a huge success on the FT circuit and the major titles just kept coming. Air Ams celebrated the 1997 Grand Prix victory with a limited run of coloured stocks having a gold winners wreath pattern with gold wording on the cheek piece.
Advert From 1999
R10's/pro-Targets can still regularly be seen in action at FT & HFT shoots, giving testament to how ahead of its time the rifle was. This is also evident in the fact that much of the mechanics of the rifle were carried over to the EV2 and FTP900 rifles.
These specifications are based on what could be considered the “standard” for each mark but Air Arms were very flexible with customer requests and would do their best to meet these requests so no doubt there would have been plenty of variations.
