Donald's ARIAKON SIM-4 conversion to .22 cal pellet gun
This particular project started life as a ARIAKON SIM-4, military look-a-like paintball marker. A copy of the U.S. military's M4/M16/AR15 type firearm. The paintball marker comes with a .50 caliber barrel. I machined a barrel bushing for the interior of the .50 cal barrel to hold the HW 16 MM O.D., .22 cal. match barrel. The stock aluminum bolt was replaced with a brass bolt. The way the Ariakon is designed the CO2 gas flows through the bolt to the projectile, I kept that design in this project. The brass bolt is thicker and seems to absorb some of the chill from the flowing CO2. The original valve system was discarded and a new valve system was designed to facilitate easier gas flow. CO2 being considered a slow gas, the idea of the new valve system was to allow more room for expansion, using more brass as it is a denser material and seems to absorb the cold from the CO2 better? I have no concrete figures to prove that statement, so the reason for the question mark. A new hammer and cocking system was developed so that the gun could be loaded but not put in battery at the same time, probable safety factor in my mind. The gun is also equipped with a trigger block safety. The receiver are in two parts, they were far from true. So they had to be milled true. The open sights that came with the marker lacked a lot to be desired. They didn't allow for accuracy, a gun that can't hit what you are aiming at is worthless. So I milled a flat top on the upper receiver, machined a riser block and added Picatinney rail for scope mounting. Initial testing shows decent accuracy off hand and getting right at 20 FPE with EUN JIN heavies. As seen in the photos I was using the "Air Source" CO2 bottles. But I found that using the 3.5 ounce buld bottles increased performance and looked nicer also.

Rick's 2240 Stace Project
This is my modded 2240 that I have been slowly putting together. Most of the upgrades are from Grant Stace. From Grant, I have acquired the breech and barrel band setup and bolt assembly. Then came the Stace trigger (this makes the 2240 feel like my Browning Buckmark) plus the tri winged gas cap, and finally the brass sight which puts a nice finishing touch to the 2240. I think the next thing for me to do to this project is to remove the "This is a toy" writing on the side. That will have to be a Spring project. I did this to my other 2240, but the writing wasn't as deeply engraved on the tube. I may try to pick up another tube somewhere and then work it over little by little, and then change it out, so I don't have pieces to try to keep track of during the project. I really like the heft that the quality metal parts give to this pistol. Many thanks to Grant Stace, who make these beautiful upgrades available.

Brandon Ripple's Custom 2250
Here's my custom 2250 and a list of what you see (and can't see) in the photos. It performs well enough at 22 good shots on a cartridge at full power. The first cock on the dual power hammer allows a whole bunch of shots at about 400 fps with the JSB Exacts. It's real quiet too.

MM's son 2250
I've been fiddling around with making a breech for my son's 2250. Thought about standard aluminum breech with dovetails but decided to go one step farther..made it a flow through bolt. The breech is 1" dia with a 3/8" bolt. The bolt has a port in the bottom and the C02 flows up and into the back of the pellet. It is sealed with a scalloped nylon transfer port mod and two o-rings. One in the front and one behind the transfer port. The bolt is press fit into the barrel so no o-ring is there. I had to re-make the cocking stud to make it longer. The loading port is my next project. I plan to make it into a multi-shot so left it really small. Although it is possible to drop the pellets in, it is kind of a pain. The plan is to replace the red dot with one of the smaller pistol red dots. The ring mount on the barrel is only temporary. The stock is small for my son (almost 7yo) and adjustable on two axis and the buttplate can be canted. I haven't crony'd or shot-counted it, not really looking to improve on either, just wanted to try something new.

Jordi Pynol's Mods
Mods in the 2240 are: The breech and bolt are from Crooked Barn. I did trigger guide and spring, trigger tune, The rear sight are an original spare from Gamo whit fiber optic. The front sight are original from a Qb78 de Luxe, with and handmade inox pipe for adapter the11 mm original barrel size to15 mm. The grips and forearm stock are home made by me with laminated wood.


In the Qb88 the mods are: Total tuning in the power plant, transfer, spring guides and main spring. You can see my work (in spanish) in this forum: http://www.armas.es/foro/foro.php?TEMA=62&MEN=623411&T=TUNING_TOTALarmas_de_resorte Trigger from Charlie da Tuna. Rework the original stock, finish with oil and wax. I put more weight in the barrel whit an iron pipe diameter 20 mm for more accuracy.
