I realise the Brocock Compatto and Bantam rifles aren't well known in S.A. but for those who have them I can offer professionally made 3D printed single shot trays for these rifles when competition rules preclude magazine loading. These items are SLS printed Graphite filled nylon with a solidity similar to a Lego brick. They are precision made for either .177 or .5.5mm rifles and offer excellent durability and value for money.
Also available are covers for the Picatinny rail at the fore-end tip. These make the stock much more pleasant to handle with a more natural forward reach.
