    M3 - friction in the hammer/valve system

    On my .22 M3 I have what seems like intermittent friction in the hammer or valve system. What happens is that I can dial in a speed, then when I use it days later, speed may be 70-100fps lower. If I shoot it long enough (LOOONG like 50+ shots) the speed might return to where it was. Maybe on...

    How many FPS is the Impact Power Block good for, vs non-power block M3?

    Can anyone comment on what sort of FPS bump they got when upgrading a non-power block M3 to power block? Either what FPS increase you saw when using the same settings, or how much lower the reg setting was after to achieve the same speed as before. I also wonder if most of the value is only at...

    Recommended Florida iguana hunt guides?

    I'll be Florida this summer and want to book a guided iguana hunt. Specifically, I'll be on the East coast and can drive as far south as about West Palm Beach. Can anyone recommend a good guide service? Extra points to ones that provide decent gun/scope combos since I won't be bringing mine...

    Looking for non-SIG BDX Rangefinder recommendations

    I had a bad run with the SIG Kilo1600BDX range finder. I ended up returning it due to a display brightness issue and unresolved bug in their app that rendered the ballistic solution values useless. It actually went back to SIG and they returned it with "No Problem Found". I really like the...

    Tuning How to do a basic regulated PCP tune - the 95% tune (plus M3 tuning simplified)

    If you are new to tuning regulated PCPs, then the basic 95% tune is a good place to start. This tune process applies to any regulated PCP with an adjustable regulator and hammer spring. It is a reliable point to tune at, and if you just want to shoot and not mess with your gun a lot, you will...

    Impact M3 liner lock - why are Orings present ONLY in 177 and .22??

    There is a different liner lock for each caliber (part 10 on the M3 barrel kit diagram https://fxairguns.com/wp-content/uploads/2021/04/F10373-pipkit-impact.pdf). The .177 and .22 versions have two orings inside (part 11 in diagram). The .25 and .30 do not. I have a .22 and .30 M3, both using...

    Tuning Impact hammer spring spacer dimensions?

    Since the .30 M3 doesn't need any part of the FX slug power kit besides the hammer spring spacer/weights, it seems like a waste to order the entire kit just to get those two spacers. I want to see if I can source something from McMaster on my next order, but my searches for the dimensions of...

    New design NSA .30 slug accuracy?

    Nielsen changed the base design of their .30 slugs this summer around the time of their move. I have confirmed this on at least the 47.2, 49.5 and 54.5 gr. Pics here: https://www.airgunnation.com/topic/nsa-design-change/ Old design has a bump in the center and has thicker base edges. New...

    Tuning Impact M3 first reg gauge sealing differences vs bottle gauge?

    From the schematics it is clear that the sealing mechanism used on the M3 first reg gauge (left side of gun) is different from the bottle/fill gauge (right side). When I had the gauges off the gun for some work last time I remember the gauge backs and even the holes in the gun looked...

    What rear bags are you using with FX Impact and bag rider?

    I have an Impact with what seems to be a very common build - Saber Tactical rear bag rider, and Saber Tactical long arca/picatinny front rail. I use an Atlas bipod on the front with the legs at 45 degrees. I looked at a lot of bags and only found one rear bag that fit the height requirements...

    Tuning How can a pin probe seat deeper than stock FX pellet probe?

    When the stock pellet probe on my .30 M3 Impact is fully retracted, it just barely clears the magazine. Maybe 1 to 1.5mm of clearance max. This seems like the minimum clearance I'd want unless really trying to split hairs and make things more high-maintenance. Now, considering that most slugs...

    My new .30 Impact M3 came with a single transfer port?

    Finally received my .30 Impact M3. Upon inspection, it only has a single round transfer port, not the dual transfer ports that are 180 deg apart. Upon re-reading some of the M3 launch literature, specifics on the dual transfer port are vague. It says "some barrels" or "most calibers" come...

    Some Rubber mulch test results

    I recently did some marauder chrony strings with a .25 shooting 37 fpe. The backstop was my low profile rubber mulch box built from 1x6, which puts depth at 5.5". This was the first time I had the opportunity to put this many high FPE shots in the exact same spot on this box, so I wanted to...

    NEW - Kalibrgun Cricket Mini Carbine

    Kalibrgun is really bad with website updates. I saw this posted on GTA and guessing someone just happened to notice it trolling the krale-schietsport website. It is not on the Kalibrgun website. http://www.krale-schietsport.nl/en/kalibrgun-cricket-mini-carabine.html

    Airgun guild forum?

    Guys, help me out. I'm totally behind on my inter-forum beefs and gossip. I have two forum memberships (here and GTA) and that is more than enough to try and keep up with. Then I see that ANOTHER forum has been created?! Its one thing if the airgun user base was HUGE and things naturally...

    Current status of composite cylinder life extension (beyond 15 years)

    I was curious where things were at with regards to the DOT granting service life extension beyond 15 years for carbon tanks so I did some googling. I found an interesting study done in cooperation with the DOT in 2015. A company took 50 expired cylinders and split them into two groups, each...

    Vulcan Gen 3 moderator/baffle performance?

    I can't seem to find any specific feedback on how effective the Gen 3 Baffles and moderators are on the latest Vulcans, especially the Tactic which has a little more baffle length than the bullpup version. I've read that the older designs were sub-par and MUCH louder when compared to what might...

    Typical price for used 66cf carbon tanks w/5-8 yrs left?

    I know there's someone on here who has been watching tank prices for a while. 66cf (45 min) carbon tanks seem to be the most common size on ebay as used fire dept stock. What is the going rate for one of these tanks with 5-8 years left? Are there any other good places to look besides ebay?
