    I am an Edgun fan. This is not a report on an issue with a gun. This is a “don’t do what I did”.

    Many of us are of a sound opinion that metal on metal friction is bad and requires a proper lubricant. We search for the best and eventually end up on a product that is amazing. Then we proceed to lubricate metal parts to prevent friction or unwanted wear.

    I lubricated the pellet probe lock on my R5M Long with my favorite lubricant AR 8300. The lock is a spring loaded arrangement that ultimately relies somewhat on surface tension/friction for a secure lock. After lubricating I ended up with a myriad of difficulties that I ultimately eliminated by cleaning the lock parts with acetone.

    Save yourself a headache… don’t lube the lock parts. Cleaning with a Qtip and Ballistol or WD40 is fine, but don’t use a lubricating oil or grease. You will most likely regret it.

    Did the same thing. But only ment to lube the sliding sled.  Blowback was the result as the lock holds the bolt closed during the firing cycle. I had to  swab the hook looking thing with a pellet patch.  The grab levers actually pivot to disengage the lock when you cock the gun.  When over lubed, the sear of the lock just slides apart. I thought it was a breach o ring at first.

    Exactly what I experienced as well. Totally self induced on my part. I just wanted to share so other R5M owners don’t repeat the error. It was somewhat frustrating and completely resolved by cleaning.

    Not many reviews on this gun.  Do you mind sharing your overall thoughts?

    I have the R5M Long in .25. I added the Huma reg and plenum when new. The gun tunes easily anywhere from 40 to 65 FtLb from my experience. I have not attemptedhigher or lower. Sweet spot with the 25.4s is 47-48 FtLb and with the 34s is right at 63 FtLb in my particular gun. I find the gun to be very quiet; although, I filled / loosely stuffed 2/3rds of the stripper vent “tank”… it’s huge… with acoustic wool. Hammer slap is the loudest sound on shot. The trigger is adjustable 2 stage. First stage is stiffer than previous EdGuns but much more smooth. The second stage is very crisp and clean. The overtravel is also adjustable. The side cocking is not as refined as an Air Arms, Cricket, Mutant or FX but it is completely usable and much more convenient than a rear bolt action. I have no complaints about the R3M bolt action either though.

    What really amazes me is the geometry of this gun. It s barely longer than my R3M STD but it is a 23.25 barreled rifle.

    The other thing that is amazing is how easy this gun is to clean / service / disassemble. Probably the easiest on the market.

    Ed stretches his barrels using the stripper tank and the frame of the rifle. His barrels are great to begin with, but this mounting provides premier ruggedness and consistency. Accuracy is very good as the gun will produce 1” groups at 100 yards with either the Kings or King heavies.

    Fit and finish is clockwork. This rifle is very well thought out.

    Granted it is my newest rifle, but it is my favorite without a doubt. Ed scored another winner with this one.

    Feel free to PM and I’ll share all you want to know. I highly recommend the R5M.

    Depends on pellet and power level.

    @ 47 FtLb shooting Kings you will get 50 easy… more like 55-58.
    @ 63 FtLb shooting King Heavies you will get 44-48.

    What’s your regulator setting for 63 ft-lb with the 34s and the larger huma plenum? Since Brian finally got the 34s back in stock I ordered a case of pellets along with the huma power kit for my R5M. Just wondering where your regulator is set so I can have a good starting point… I was thinking of starting at 120 bar. Thanks!

    I have both the standard and super long, but couldn’t pick a favorite. Like the standard for carrying, but the super long has such a long reach. I guess it’s how the rifle will be used. I have the zero at 40 yards on the standard. The zero on the super long is 100 yards.

    Haven’t chronographed either rifle, but the standard is shooting the NSA slugs 21 shots per fill. Once you try those slugs you’ll never shoot pellets again! Edgun regulator, haven’t found any problem with the tune that the rifle came with.

    Nielsen Specialty Ammo , they are 47 grain staged bullets. Yes they are hollow points. I normally don’t shoot paper, but am a pest and small game guy. That’s why I like the Edgun over the other quality rifles, it’s designed to be a designated hunter. Yes I have shot all three of the JSB pellets.  All are accurate out as far as the scope can be used, which is the limiter of these rifles. The hollow point is devastating to live targets.

    “JWilson”For the long you are going to want right at 130 Bar on the reg.

    Got the 34gr pellets on Wednesday, but USPS decided to misroute the Huma regulator & plenum kit which delayed it until today.

    Anyways, did some tuning/testing tonight. The sticker on the Huma regulator is about 5 bar low compared to the reading on the 4″ 1% accuracy Wika gauge on my regulator tester.

    Here’s the results with the Huma plenum kit on my R5M long with the .25 34gr JSBs… regulator pressures are from the gauge on my tester, not the Huma label. Velocity numbers from a Labradar. Brian suggested starting at 120bar.

    120 bar = 870 peak fps, so tune HST for ~855fps
    125 bar = 890 peak fps, so tune HST for ~875fps
    130 bar = 910 peak fps, so tune HST for ~895fps

    I left it at 130 bar with the HST set for 895fps. From a 230 bar fill it’s about 45 shots per fill before falling off the regulator. It gets 4 good shots off the regulator with the velocity gradually falling from the normal 895fps down to 875fps at 123bar on the EDMU. Need to rezero the scope and test at 50Y, 75Y, 100Y, 125Y, and 150Y tomorrow to see what the 34gr pellets do for drop out of my barrel and figure out a BC number. Can’t wait to try the 34gr pellets on some 85Y+ ground squirrels and see how they do compared to the 25gr pellets.
