Breach Insert for Air Arms MPR S400 Rifle. This has been a winning choice for Target Sprint athletes to enable faster loading of the rifle without missing the breach and overthrowing the pellet. As with the insert for the TS400 this also covers the bolt when the bolt is retracted avoiding the placing of the pellet on top of the bolt. This is friction mounted to the rifle by positioning flat over the breach and pushing down vertically. Then easily removed by following this in reverse. Can be ordered with Right or Left opening. Specify before adding to basket.
