The use of synthetic foams for the production of butt guns is now a widespread and consolidated practice all over the world. Compared to classic natural fiber arrowheads, the synthetic has the advantage of being less subject to degradation due to atmospheric agents and having a softer impact on the arrows. This translates into a longer life both for the butt and the arrows, which is very appreciated by archers and by those who organize the demonstrations. The possibility of choosing from a very wide range of products, the very low weight and the availability of spare parts to replace the parts most subject to wear make this bolt an ideal and extremely flexible complement for the preparation of shooting ranges.
