Sub2000 Gen1 HiPoint Front Sight Adapter

The Gen1 Sub2000 had a plastic sight that is….not good.  Some people found that they could use a HiPoint front sight https://hi-pointfirearms.net/product/front-sight-2/ as a replacement, keeping the front barrel sleeve on.  Some of us, however, removed that aluminum barrel sleeve as it's just glued on to the barrel.  

This model allows you to remove the aluminum sleeve and add on the hipoint sight, and also retain the stock latch that keeps the rifle folded.   

I'd highly recommend printing this in a high-temp material – i used PA-CF, both because the PA is high temp and because the CF material tends to not absorb heat very quickly.
