The AE Swede Benjamin P-Rod .22 extended capacity magazine is made by CNC machine from Delrin plastic which is a very high quality, long lasting and long wearing plastic. Only the best materials and design work go into these magazines. You will not find a better magazine for the P-Rod any where.
The magazine holds 18 shots. Load the first pellet from the back then top load the remainder and you normally would.
I support all of my magazines with spare parts should anything ever get damaged a new part can be purchased instead of having to purchase a full magazine.
