Marcelo Cerdan from Argentina sent a few more pictures today of his two rifles that he completed.
Schaefer’s page 5 updated
Mr. Schaefer sent 4 more pictures of his current build. He has completed a stock and mounted the rifle action to the stock. Looks pretty sharp! He is using a Crosman clip from a Marauder.

Buckley “Concept 4” Airgun Target Groups
Here are a few videos of some target shooting I did this morning. Nothing to impressive as I could only get 30 feet away. But at least it was indoors. -16 C this morning.
Another picture of the rifle in its current state.

Here is the first real groups after sighting in the scope. Used my B-Sqaure scope.
The videos are edited, I cannot load and shoot that fast with a single shot rifle. Here are more grouping shot this morning.
More to come when I have time. Need to finish the butt stock and then the handles. Will be awhile now before I continue, winter has approached! Thanks ~ Pedro

Concept 4 More Progress
Today I made the striker knob and the bolt knob. I was also able to start on the wood forearm stock. Starting to look like a real rifle. I forgot to get the aluminum to create the butt stock but didn’t have time regardless it was my dad’s birthday today so went their for supper.
I hope to do some shooting soon to see how this airgun performs.
I have rifles almost complete minus the stock and wood.
I haven’t been able to finish all the page links but here are two new pages of pictures for the concept 4 rifle.

I hope to link all the pages soon. I have pictures from Schaefer on his new build and will post them soon. Thanks for reading.
After a very frustrating morning, I was finally able to get to the shop to work on the air rifles. I managed to get one of the rifles to fire by 8pm. On valve is leaking so have to work on that. Valves either work or leak and finding the perfect combination is tricky it seems. I realize now I should have made the valve a 2 piece design.
I worked on the triggers and sear. I had some springs but they are to weak and will have to get some heavier springs to make the trigger and sear engage more consistently.
Below is a video showing a few shots and first pellet shot. I will add to the web page when I can as I have many pictures to add from last 2 weeks of working on this project. The rubber bands are holding 1/8 drill bits in place to locate the trigger and sear and kept falling out otherwise.
Next few weeks will be focusing on the final machining and assembly as I can. Thus far a very mild fall here in Manitoba, but the snow and extreme cold are going to pounce on us very soon!
Comments, please feel to tell me what you think. Thanks for visiting the website. ~ Pedro
Concept 4 – Buckley inspired rifle
I have been able to do some work on the Buckley inspired reservoir airguns I am building. I have finished machining the valves, hammer and now need to make the triggers and sear. Hoping to have this completed on Saturday Nov 6th and should be able to test fire shortly there after. I will update the pages next week when I get a chance.
Concept 4 – Added Pictures
I added some pictures from October 11 to the page 5 of the Concept 4 airgun.
