I am looking for a jig to rent where can u rent themMy vote is a Cetme C. It’s the predecessor to the HK G3. Part kits can be had for $99-150. You can bend a flat with a piece of unistrut and 20mm rod, or borrow a bend jig. I’ve got a couple waiting to be built along with a sten, and a KGKT. Another good cool/cheap option is a Suomi M31
