This is my first attempt at making a bullpup, and the project has taken a couple of years. I went down some dead ends on the way, and made some major changes along the way, too. It is already spoken for.

Started with a Benjamin Marauder Pistol and an Airgun Lab P-Rod Double tube kit. The stock , which is a compilation of some other designs I have seen, is made from obeche, a soft, light, straight grained wood often used for interior and exterior trim in houses (at least in the mid-Atlantic coast). It is very easy to work by hand. I used a small drill press with some big Fostner bits, some sanding drums, a router, wood files, and lots of sand paper. The obeche from the lumber yard was 5/4 x 6 (actual size 1" thick x 5-1/2" wide) and I doweled the 2 halves together so that I could take them apart and together during the build. I ended up gluing the 2 halves together before final sanding and finishing.

The gun slides in and out of the stock in alignment with the pistol grip frame, looking at the picture, in the 1:00 o'clock direction. A pair of brass 8-32 pan truss head screws (cabinet door handle screws) secure the stock to the gun. The butt pad is one that I got from Numrich gun parts in " six NOS and used butt pads for $15," type of deal. This one worked perfectly, and the name molded into it is : Pachmayr Gun Works, Los Angeles, Calif. Maybe a bit of history there.

I started with standard length tubes on this gun but ended up making everything about 5" longer. The shroud and a lower air tube are one-piece, and the main tube has a 5" extension. The front barrel band clamps all the tubes together and has a Picatinny rail on the bottom. Final OAL is 25", weight without scope is 4 lbs 14 oz, and it holds a whopping 220 ccs of air. (Standard P-Rod capacity is less than 70ccs)

The scope rail is a Picatinny style from XpertGear.com. They have some unusual stuff and their prices are good. Unfortunately, the rail had a Picatinny bottom, also, so I had to mill that off and then mill a dovetail slot to match the P-Rod receiver. It turned out pretty decent, but the scope in the picture isn't really appropriate for the gun.

The trigger took a few attempts, including a couple of them in the junk pile. This one is made of .250 dia SS tube with .025 wall (I think) that I deformed enough so that it would take a 10-32 tap. The trigger shoe is just a section of aluminum tubing with a flat head screw securing it to the SS tube. I split the other end of the tube with a hacksaw and then heated it and bent it into a fork to fit the trigger adapter that I made. I had to heat the thin wall of the tube to keep it from cracking when I bent it. The adapter for the P-Rod trigger was a major pain to make, but it finally worked, and it stays put.

I have a light spring that takes up the free play in the trigger linkage. The tension in the trigger assy had to be raised a bit to compensate. Also, the safety is not active (not a good thing) but I could have drilled thru the sides of the stock to make the original safety accessible... I think so, anyway. But now that it is all glued up, I doubt I could do that without messing something up. The groove in the aluminum attachment block and the channel in the wood, keep the trigger linkage in alignment. I am actually kind of surprised how smoothly the trigger functions. Maybe I got lucky on that count. Or maybe its because it was my third design, ha, ha. This sort of thing just takes a lot of time, and a willingness to trash it and start over when you know its not right.

Here you can see the 2 brass attachment screws. The pistol grip slides snuggly down at an angle ( down in the 7:00 o'clock direction in this picture) into a pocket and everything ends up married nicely together.

Here the beauty is. It needs an appropriate scope, and a cheek rest, but other than that, it ought to do OK.

Joseph, I haven't given it a tune yet, but it could certainly be tuned pretty hot with that amount of air.

Matthew, Thank you! Glad you like the look.

I like it. It came out very nice, color on the stock came out great! The stock, double tube & cantilever rail (perfect combo)!

Aw shucks guys. I'm gonna get embarrassed.

But thanks. One of those projects where the second one would take half the time to make.

Now you have to add a SSG... and report your findings...

. My Rapid mini-bullpup will soon become a vintage item

Very nice Lloyd now get someone to make a kit. With your Bull pup a plastic stock makes sense for the market and maybe a walnut stock version for the purists out there

Very nice! Is that DIY rail or are those for sale somewhere?

The scope rail is purchased and modified. I describe it in the paragraph directly above the first picture in the post. It is stouter than I thought it would be.

That is one sweet rig Lloyd.
So when can i place an order for one

Tonycalves · « **Reply #18 on:** January 23, 2016, 02:00:16 PM »

WOW! That's beautiful. I just sold my rapid 70 Prod pup because it was too small, that 1 looks perfect.

lloyd-ss · « **Reply #19 on:** January 23, 2016, 04:48:36 PM »

You might call this "A gun of a handy size."

I just noticed that I misstated the length, though. Overall is 25", not 23". I will fix the picture. The weight of 4 lbs 14 oz w/o scope, is correct. It's pretty compact, and probably too small for anyone over 5'-8".
