You guys deserve every ounce of success in your endeavours! As an apprentice machinist, I'm excited to see peeks in to the manufacturing processes that you can allow. Much love from Canada!

[@oddspaghetti4287]

One thing that came to mind on the subject of the sighting system. During my army service we used red dots with that very same mounting mechanism and with it being on the left side of the gun it is really easy to catch on your webbing etc. accidentally opening it and dropping your sight to the ground without you noticing, two guys lost their red dots in my platoon that way and we had to all go and search for them for hours in the forest. So I would either suggest rotating the red dot mount around to the other side so the lever is on the right side or using a different mounting system, this is especially important if you do not have backup sights.

[@yuibot5998]

Just finished putting mine together and put a Aero upper/faxxon pencil barrel and midwest handguard. It's nice and light. Can't wait to test it out. Had NO issues putting the lower together, only had one tiny area I had to trim a few hairs of flashing with a knife...took 2 seconds.

If nothing else, this video does a really good job of explaining why gun development is slow and expensive. They're in the final stages before mass manufacture and release and it's all the little pieces just coming together. X supplier using Y product on Z tooling with A second line processes and B QA and C paperwork and D contract with retailer, with incremental issues at every single step. If you've ever spent time around manufacturing, this is 100% normal.

[@Fudmottin]

I received an FDE version of the KP-15 recently. It had a bit of flashing on the top of the stock portion that I didn't like. After a quick pass with a Dremel and some sand paper, I cleaned it with some CRC brake cleaner. That did no visible damage. I would avoid acetone though. That stuff dissolves ABS plastic and quite a lot of other polymers. I was very sparing with the brake cleaner. I sprayed a rag and used that for wiping down. It evaporates very quickly. I wasn't willing to spray it directly onto the stock.

A telescopic stock is impossible, the fixed stock is necessary for the strength of the receiver. If it had just a regular buffer tube mounted at the end, that area would be a huge weak point. The fixed stock allowed them to add material and shape the stress to strengthen it.

[@gregbrown4009]

Just a thought about flash removal. Design all exterior flash surfaces with a flat bevel from .25 to .38 wide. Let it flash over this bevel on molding. CNC it in one pass back to the designed flat during the same process as hole drilling and other operations. Molded margins look cheap. Period. End paragraph. You stated the material is very robust, so any manual method will be impractical. By designing a flat from the start, you eliminate the molded look (material is assumed to be 100% fused without porosity) and have a clean, smooth surface. Especially handy for the charging handle to glide on. Keep up the great work!
