Man I love you idea because it will look way better than the original IMO and I happen to have a CTR laying around and spare grip myself. I have no need for a bump fire style stock but sure will be fun shooting once in awhile . I believe I shall build one myself just to play with from time to time. Wished I had a CNC machine I'd build a complete billet setup.

i searched for several hours and could not find a single case of an individual who was forced to comply with a c&d order for something (anything) made for personel use with no intent or attempt to market the product.... ford was unable to stop chevrolet from developing a v8 engine because chevrolet never sold their v8 until fords patent was no longer applicable , but.. chevrolet was building and IMPROVING the v8 for years. ford sufferd no finacial loss so there was no infringment. if u research patents u will find an untold number that are granted for an IMPROVEMENT on an existing patent. if inventors had to wait years untill a patent was expired to try and improve upon it or the DIY guys who enjoy tinkering were made to pay someone for something they built we would all be screwed ... who would even try if ur gonna get sued ? yes u can patent an idea that leads to a product....does that mean the patent holder can have a c&d order sent to me if i think about his idea...?
and .... if it comes to it i will contribute gladly and generously to your legal fund if u r sued for the stock that u made for your PERSONAL use
sorry for the mini rant ....got up to early and stayed up to late : )
john
ps i have bought 1 sfs stock new and 1 used ...and i have made 2 for my own use and for my grandson.. this thread has given me and inspiration to build a 3rd
so im goin' to the garage right now... thanx for posting about your DIY slidefire TYPE stock .
i guess i gotta worry about the patent office jbt's com'n after me now

Props the the OP for your ingenuity and execution. Looking forward to seeing your Gen 2 version here.

I know what you mean, most of the fun is in the garage pounding stuff out....good job

I think what you've done there is pretty neat. Bump firing isnt for everyone. But it has its moments like you mentioned. (friends, family––––to show it off as something different once in a great while) nothing wrong with that.
I say keep going man. Screw people. If you enjoy working on this kinda stuff do it. Who cares how much time you've put into it. In the end if you enjoyed your time spent on the project I say its a success.

you're doing something i couldnt do.

Edit: And i think the "lecture" guy just likes to see his pretty little words on the screen whos bustin' balls now! lol ..all in fun

Patent #8,127,658 long but interesting read...

That is impressive.

looks amazing. good work. Im trying to figure how to do this with normal ar15 m4 stocks and grips.

I'd thread a bolt into the stock right behind the adjustment lever with a small piece of flat steel that has a hole drilled offset from center. Then to use it as a bumpstock you would compress the lever, slide the flat steel ontop the lever, and when you let go of the lever, the flat steel will keep it from decompressing. The only downside of this would be the flat piece of steel possible rattling, but a spring between it and the stock might solve that.

Have the buffer tube length adjustment milled out so that the detent in the stock keeps it on the tube but won't lock up, just slide freely back and forth in the area that the position holes are. problem easily solved, don't over think things.

Here's an idea too. You could get a longer bolt for the rear bolt hole on the metal rod and drill out that second layer on the stock itself, then thread an extra nut on for back pressure, and run the longer bolt up til it locks the lever up. I'll try to MS Paint this.

ETA: The second nut is to keep the metal bar tight against the stock.

That was my worry. CFCNC's idea is better, I think, just harder to execute.

If you dremmel them out, just put the stock back to it's original configuration and it will keep it on and still slide back and forth with ease.... win win. The only downside is that this buffer tube is worthless for anything else, but it solves the problems you are facing. One other thing you could do is shave down the detent so that it won't make contact with the locking holes, but still keep it in the grove so it won't come off.
