I've been developing a drop-in bullpup rifle chassis for your bolt action!

V2 looks good! One thing; the magazine. looks like you have an M1A mag setup in V2; pro: easy availalbilty; con: limited to 4 calibers, one of which is virutally dead. (.358 Win.) Using the AR 15 mag will present design challenges, a lot more machining and small parts. Suggestion; there are several good aftermarket designs of M700 mags out there, for both short and long action. I suggest you utilize one of them. It appears that's how your first drawing has it.
Glad to see Timney working with you on this. It can't hurt to have the top name in triggers on board. and it frees you up to work on other aspects of the rifle.

Well, I wouldn't buy one, but I do appreciate innovation, especially in the firearms world!

Keep up the good work. I am sure somebody out there would be thrilled with your product.

Check out the desert tech SRS or covert. They got the bull pup precision rifle right, albeit not a drop in style chassis. It is my favorite rifle I have ever gotten to handle. You might be able to pick up a few things for the next revision!

As far as ergos, on the DT rifle you get used to it. It is different, and the bullpup may not be for everyone. Its one of those try it first kinda things. I do not have any issues running the rifle while still maintaining cheek weld, position and POA. The rifle balances VERY well for off hand shooting and with a 16 inch barrel is under 30 inches OAL. A LONG barrel puts its OAL on par with most typical medium barrel rifles. Your V2 looks similar enough to what I am experienced with that I think it would handle well too. Nice work!

Trigger on the DT is plenty excellent. Not a jewell trigger mind you, but it will not be something you can blame poor shooting on lol. No reason a nicely executed bullpup has to have a garbage trigger; it just takes a little work to get it right.

One thing you may look into is a way to adjust comb/cheek rest height if possible. Good old mouse pads and tape are not for everyone, though they do the job haha.

Your V2 looks great. I say go for it if you can get your chassis workable. I would be interested.

This really looks like an exercise in solving a problem that DOES NOT exist in bolt actions......the ergonomics alone are a disaster

"ROA, care to elaborate?"


Sure......when locked down....taking a bead on a very distant target.....having to unlock from shouldered weapon...losing a sight picture...to cycle a bolt...then reacquire a target that at a distance will be a search that time may not allow........with a "normal" long range precision rifle...one does not have to lose the sight picture to cycle the next round

lets not overlook the basic mission a bullpup design addresses......quick handling in confined spaces......which a bolt action is not suited for....does anyone really think that a bolt action will be used in confined combat???

as a precision rifle (aka sniping)...quick agile handling really is not an issue....

"extended bolt handle"......projecting forward to what is the normal location of a bolt action ???? kinda gives it a long projection perfect for snagging on objects? and with that acting like a lever will induce a caming effect on the rear of the bolt...with the added drag/friction to open the bolt

It might require modifications and upgrades along the line, and I still think it's better suited to a straight pull action, but more power to ya'.

I like the new and improved V2! Have always been fascinated by bullpup designs but primarily with a semi-auto action. Please continue on with your work and keep us posted.

I have pondered this thread since its last posts.

As others mention your choice of a bolt action is somewhat pointless due to the ergonomics of working the action.

But people myself included like a single shot for its innate compactness.

I would buy a very short bullpup single shot, being a single shot would eliminate the cycling paradox you have.

Another vote for a single shot with a simple opening operation.

You could get something like a 26" encore pro hunter down to a length that may not even be legal.

I could envision just a simple op rod that takes care of cocking the hammer and moves that operation up by the trigger mechanism

Nice work, OP! A little bulky, but good lines.

I do, however, have to agree with others that there's a reason bullpups have never been especially popular, especially in bolt actions. Compact and handy, but they effectively become heavy single shots due to the ergonomics.

Your idea for bolt handle extension helps, but not unless you increase the distance on the stock to where the bolt will not hit the shooter's shoulder. On that note, I'd suggest a camming action from a straight pull extension. Think Yankee screwdriver. Fewer parts, and less parasitic loss of force than working through multiple articulating mechanical connections. Take a look at the op rod on an M1, M14 or mini-14 for ideas there.

Only if you cut the 26" barrel........

You are if corse correct. I'm not sure why I said what I did.

How's this. You could get a 26" barreled gun down pretty close to the ATF minimum OAL

instead of that, develop me a straight pull bolt action with large detachable box mag that can also be slam-fired

I appreciate all the input.

I think there is a sizable market for this chassis, based on the amount of interest I've seen so far. One thing people seem to forget, and I don't blame them because I haven't posted any pictures of, is the bolt extension. The bolt won't travel into your shoulder, it doesn't increase how far it travels backwards. The bolt handle will simply be in a more conventional position.

As far as a single shot bullpup...it would be neat but I don't think the market numbers are even close. If I was proven wrong I would certainly seriously look into the matter.

tykempster, would it be helpful to have someone machine/3d print components for you? If yes, I am quite interested

For bolt handle position, have you checked the MAS 36? i.e. bend it forwards. If you are going to change things, you might as well change things.

What's your price point looking like?

I ask, because I had a lot of interest in this:



Until people found out how much I'd have to charge to make them for sale.

The same happened with my Ti comps & brakes, as well as custom 7075-T651 RC car parts I was doing. You'll sell a few, but most people simply won't pay what it costs for custom or higher end, low production semi-custom stuff.
