LightWerkz, you mentioned two slots to secure the tips; only two out of the four stock holes to secure the tips? Do the tips seem secure enough with only being two pointed? Also, are those production items??
Sorry for the questions. There isn't much, if any, info on these tips as of yet.
IMO, I would imagine designing the tips to fit the same way the say stock (ei: rivet holes not slots and four attach points vise two) would take a lot of the guess work out.
