Previously I talked about how I got a 10/22 take down.
I wanted something like a tri-rail handguard for it, but I didn’t feel like spending the cash for one and the few aftermarket handguards I saw online didn’t really suit my fancy.
Yesterday, I woke up thinking about a M-LOK handguard for the 10/22. I took the factory handguard off and realized making a replacement handguard would be pretty easy. There is just a rectangular block under the barrel.
So I took off the factory handguard, grabbed my cheap beater pair of calipers, and spend about 10 minutes in CAD software. I drew up a fast and crude proof of concept. I exported the design as a STL file, imported that into Prusa slicer, and outputting some code for my 3D printer. About 3 and a half hours later, and about $2 of plastic, I had my proof of concept handguard made.
While it worked, it was lacking in a few areas. I left off any fillets for quick design. While the 3D printer doesn’t really make sharp corners, sharp corners are not good for a design. The areas where the M-LOK lock in where too thick. I also figured having the handguard come up over the top of the barrel was not that good looking.
The biggest problem was I forgot to give a clearance for the take down latch. With the proof of concept handguard I have to use a tool to take the gun down.
Before I went to bed I hopped back into the CAD software and made some changes. I lengthened the handguard and added a few more slots. I adjusted some of the dimensions and added some radiuses. Most importantly, I put in clearance for the take down latch.
I started the print before I went to bed. I work up with a new handguard threw it on the printer. $3 worth of plastic, and four something hours of print time.
Rough draft is the name of the setting I used. 20% infil means that about 80% of the inside of this handguard is just hollow. Making this rather light weight. There is some flex in the handguard, so I wouldn’t want to trust mounting a sight for serious use, but I am very happy with it.
It is good enough for now.
