    EDgun R5M/Lelya bolt block disassembly & component pics

    Hello all, Here is a reposting of some work I wrote about in a different forum subsection. I thought it would be helpful to put it where it belongs, in the resources section. I disassembled, cleaned & re-lubed the bolt block on my Edgun R5M. I'm pretty sure the Lelya uses the exact same parts...

    Recognizing Bad O-rings

    Hello All, While servicing the regulator in my EDgun R5M, I discovered that several o-rings had gone bad. I made some photos before and after replacement, to help illustrate what they look like when they go bad. New ones in the upper photo, have a nicely symmetrical rounded profile above the...

    EdGun R5M/Lelya Regulator & Valve Component Pics

    Hello All, I recently serviced & re-sealed the regulator in my 2019 Edgun R5M and used the opportunity to take and annotate some photos of the parts. Annotations include O-ring sizes, notes for polishing and deburring, part orientation, and regulator screw adjustment. This should also apply to...

    Edgun R5m Fill Pressure, Regulator Creep & Broken Valve Lessons

    Hello all, I thought I'd take a moment to share a story of a surprise failure of my 3yr old Edgun R5m in .25 caliber. I originally tuned this gun to shoot JSB 25.4 gr at 875 fps (54 clicks CCW from full CW, for those of you who have worked on Edguns), where it has performed beautifully until the...

    Leshiy Folding Grip with Tools & Range Table

    Hello all, I thought I'd share a couple of enhancements I'm working on with my EDgun Leshiy. I added a UTG 5-position folding grip to my Leshiy. It has a tool storage compartment that I thought would be perfect for storing the two hex keys (2.5 & 6mm) needed to change the barrel and adjust...

    EDgun Leshiy Barrel Indexing/marking

    Hello all, For those of you using multiple barrels with your Leshiy, do you index them so that you can swap them in and out with the exact same orientation they were originally sighted in for? If so, what is your preferred method for marking? My intuition tells me that I may have to tweak the...

    25 Cal Polymag Recovery

    Hello all, I thought it would be interesting to recover one of these 25 Cal Predator Polymags and see the pellet afterwards. This one was fired at about 785 fps/36 fpe from my new Edgun R5M Hornet. Range was about 12yd on a squirrel, passing through the side of the skull, angling down through...
