I came across a used Hi-point classic carbine for $120. It's a gun I've wanted to shoot for a while, and the rest is history. The particular rifle I bought had a few cosmetic issues from neglect, and I had some questions about the rifle anyways, so I made a quick call to technical support. Q: what ammo/grain weight do you use for accuracy testing A: 115gr Aluminum case Blazer was the tech's go-to choice. Q: what's the best way to clean up the rifles light surface rust (w.high likelihood of gun being buried, zero concern for resale/collectibility) A: wire wheel, and hit it with light coats of rustoleum. The barrel shroud does not get hot, so no high-temp paint necessary Q: is there a safe way to reduce the trigger pull weight? E.g. spring swap A: yes. Take the gun apart to get down to the trigger assembly. 1st clean out all debris. 2nd some of the disconnector linkage will rub/drag against the shroud. The thickness of the linkage can be carefully be filed down/made SLIGHTLY thinner so it doesn't touch the shroud. Leave the springs alone. This process is now being done to the current production carbines. He asked the serial number of my model. Mine's an older one. He mentioned there were some durability improvements made, that my rifle would benefit from. Some of the older stocks also had sagging issues that could mess with accuracy. We talked about options for adding optics. He said Hi-point has a pic rail that can replace the original sight bridge. He asked me to send the rifle back to make the durability upgrades (recoil lug?). After our conversation, but prior to shipping, I noticed the trigger had about 1/8" of lateral play. Not sure if this is/was normal or not, so I mentioned it on the return form. Fwiw, the trigger pull weight prior to sending back was 7lb's, but really inconsistent (ranged from 5.5lb to off-the-scale). I didn't go into the phone call asking or expecting anything from Hi-point. I honestly just wanted to learn and pick their brain. Just a pleasant overall experience talking with them. Will do a range report (I haven't even shot it yet!) and follow-up when the carbine comes back.
