Rob Allen Bulk Rubber
The Rob Allen rubber is manufactured by a dip processing routine. While costing a little more than the average rubber, this enables fewer additives are to be used which enhances performance on the guns. The blue colored outer layer increases protection from the environments because it is coated and the amber inner core is what gives you the performance. It is available in 16mm, 18mm and 20mm thicknesses. The 16mm is generally for lighter 7mm spears, the 18mm and the 20mm is ideal for longer single rubber guns with heavier spears such as 7.5mm. Majority of guns will come standard with a 16mm rubber, however they can all be upgraded for more power. There are 2 ways of increasing your power. First is to add a second 16mm rubber on to your gun, you will have to check if this is possibly on your particular gun as some only take single rubbers, however if your gun can, then this is a good option. Secondly, you could take off that 16mm rubber and put a single 18mm or 20mm rubber on it instead, this will give you loads of power and is simular to 2 x 16mm rubbers.
