Got the manual? Nipple size should be in there. Otherwise, Dixie Gunworks is the place to go. http://www.dixiegunworks.com/default...b92de6c31de00e

Investarms uses metric M6X0.75 threaded nipples. The SAE specs on that thread are 0.236" MD and 33.9 tpi. There is no direct SAE equivalent. The Treso part number is 11-50-03; Track of the Wolf's catalog number for that part is RLP-A: Track of the Wolf thread chart
