THE IMAGE ABOVE IS A PAID ADVERTISEMENT
I know we have all seen and heard about the Slide Fire Solutions bump fire stock.
Well, as like most of us, I didn't see the point in spending $350 or more on one of these stocks.
The argument about how they are cheaper than the the cost of a full auto lower is entirely
true, however, I do not think they are cheap enough. I set out to create my own while trying to
keep it as cost efficient as I could. Let me know what you all think.

For those of you who wanted the updated design first, here it is:

Can anyone say "patent infringement" .

I am not an attorney and I believe that you are legal to build a device that is patented for your own use. However if you ever offer one for sale, you can be sued for infringing on their patent.

As a second point, how much time have you spent building the stock? Is your time worth anything? You can quickly spend more building than just buying one used on gunbroker

As a final point everyone busted on Slidefire for building an "ugly" stock when their product first came out. Theirs has nothing on ugly compared to yours.....lol

Alright bud, calm down. I thought the idea up and created it, in less than 24 hours total.
I saved 350 bucks, and had a lot of fun. Are you not understanding this? Also I have NO plans
to sell this. It may be ugly, but it works, and it works just fine. Wait till you see the second one.
You have NO idea how much better it is going to be. As I said, just trying to have some fun,
no illegal intentions whatsoever, private use only.

I think its cool you designed and built something yourself, and it seems to work.

I have no desire for any bump fire type stock, but as long as what you have is legal, kudos to you.

Question... How would I go about VERIFYING that this is 100 percent legal. I am pretty sure it is, but I am not the ATF, and if it will silence the people that are going to post about it being illegal, I will make sure it is.

WOW looks really cool. Seems like the same thing to me just a little more ugly. I dont see how anything the op built is any different than how the slide fire works. Good job OP for thinking outside the box OP.

I like it! Good for you for saving a few $ which will easily go to more ammo for it!
It's ok because each pull of the trigger is firing 1 bullet...... Not a machine gun.......it's like he is pulling the trigger really really fast

As I said, this is an UGLY prototype, it was mainly to make sure it is going to work.
The second one, which I SHOULD have done in the next week or so will look much better.

Dont put your finger on the trigger until your ready to fire

Good job making your own. $350 is outrageous for what it is.

Chill... I am simply pointing out facts you need to consider in what you are building.

You are starting out much as the Slidefire guy did several years ago. He had an idea, he developed it much as you are doing, and then he spent several hundred thousand dollars, taking it to market.

He also spent tens of thousands of dollars getting the patent. As long as you are building for your personal use it would not likely draw any attention. but still an infringement.

Honestly, I am not busting your balls, you have built a replica and it seems to work well. Just don't go into business selling them

I understand where you are coming from, and am glad you pointed it out.
I'm the tinkerer, and not so much of a salesman. Even if I had the ability to sell it,
and the rights to do so, I don't think I would be able to. I don't really possess the know
how to get a business going.

What's funny about all of this, is that I saved 350 dollars doing this, and will probably spend way more in ammo for sure.
So far I have only shot like 150 rounds or so through it, but can see way more rounds coming. The rifle in this video was
not mine, it was my friend Kyle's. I needed one with a removable butt stock, as my AR has the Magpul M93 on it. I didn't want
to drill into that stock by any means.

This is going to sound kind of odd, but I am going to end up buying a second lower, so I can just keep my bump fire stock on that,
and switch out lowers when I want to shoot single shot. That is the main reason I am making another stock, so that I can make
sure it looks and works as I would like.

Hopefully for the next video I'm thinking, CMAG full of tracers, SPR/M4, and night time shooting.

This is what I tell people in my shop. The cost of the ammo far exceeds the cost of the stock.

ETA: 1000 rounds at 600 rounds a minute= 2 minutes trigger time

This is true. I'm pretty sure the sensation of shooting this is going to die off fast.
By then I will be able to actually keep some ammo. But where I'm going with this
is just a show off toy to show every once in a while. Maybe if friends come in town
and want to go shooting or something, I can show it to them, stuff like that. Not an
everyday thing.

Honestly, even with the huge bar sticking out the back, I also think so, but this next one I'm making is going to eliminate that bar entirely.
Y'all just hang in there, I might have some time to work on it later tonight.

Hold out for the $40 Chinese version...
I'll save my thoughts on the people who can spend any amount of dollars on a rifle but can't devote 20 minutes to getting their body in shape for another thread. -skinnysarge79

personally i think the whole bump fire thing is silly, but you did make something yourself that works and you like it, so good going. can't knock a guy for trying something. still, seems like an excuse for a mag dump. thing i enjoyed the most was the audio on the clip."bbbbbbbbbbb BOOM!"

Really? Lecturing the guy and then telling him his contraption is ugly isn't ball-busting?

Brodband, I like it, it looks cool as hell, and it is a cheap alternative for those of us who would like the option of trying controlled bumpfire without plunking down $350 to do so.

I have always thought the SlideFire was neat, but if I did get one, the novelty would probably wear off fast (ammo = $$ as you said). With your contraption, I could do it without burning through three and a half c notes.
