My first .177 pellet gun

Unread postAuthor: farcticox1 » Sun Aug 19, 2018 4:51 pm

.177 smooth bore (.183" ID seam less tubing). Barrel is 750mm long and uses a 24vdc solenoid valve, chamber is 1" x 12" sch40 stainless steel charged to 150psi from my compressor. Single shot bolt action. BB's not so accurate but the dome head lead pellets are pretty good :D

150PSI is safe to use push to connect fittings and hoses, you could have routed a larger chamber inside the handguard and have multi shot capability

Weapons do not exist, they are built. This hobby is a science - totally procedural art.

Not yet, I will need to make an adaptor to fit the new barrel size.

No it's mostly aluminium & stainless chamber and barrel. It's pretty simple really.

Took the scope off and making a peep sight as I only want to use it up to 10m range, rear sight has windage adjustment, range will be on the front post :idea:

Peep sight fitted, works nicely, had some adjustable stock parts from another build I didn't use so fitted that and made adjustable cheek rest as well.

Following on with the KISS principal I have changed the barrel to 6mm ID to use airsoft, I made the barrel slide now so the dead space will be minimal + less leaks. The tube I got from McMaster Carr is 8 x 6mm but was only 5.85 ID :( Much polishing later with a long rod and abrasive cloth and a BB rolls down it. Haven't tried it yet. Also mounted my old 4X scope offset to the left of the peep sights so I can use it as a spotting scope :idea:

The offset bits are very appealing. Informal balance FTW!

Never being really happy with anything I pulled it apart again, changed it back to the .177 barrel, now at only 12" long (cut down the body), and made it a sliding barrel, much easier to load and zero dead space. Some work on the sliding stock also so it goes fully in.
