Gorgeous - where did you get that muzzle break? Purchased mine last month from AoA, am only getting about 815fps with 8.2g Meisterkulgens. Had AoA check their floor model, same. Everyone else on these forums posts much higher numbers. Curious what velocities you're getting after Scott's tune-up. That's probably my next step. I have already had the gun apart, did the basics - replaced the ridiculously loose piston seal with a red Maccari seal, lightly lubed the seal edge with ARH "super moly". The spring, guide and piston rod already had a little factory moly. After all that, velocity went down but I noticed the piston seal was tigher than factory. Sanded it down a tiny bit at a time, got velocity back to original. But still 40++ fps below what others are reporting. Thinking that Scott will be able to do a much better job at dialing everything in. Amazing how tempermental these guns are to tuning... Took me almost two months to get my Anschutz 380 working to spec. That was mainly a parts issue, but holy cow what a learning experience.
The muzzle break is the 12" apex that Maccari sells;
Thanks RicL. Understood re: tune, I’m most interested in a smooth shot cycle without the twanging. My interest in velocity is merely that others make claims of higher numbers, leading me to believe the gun isn’t properly tuned. I’m plenty happy with it’s 12 fpe If that’s what the gun is designed for… specs seem to be higher.
I also bought two, leaving one in-box. It had a blemish so had to return it. Haven’t decided if I’ll purchase another one, but agree with you it’s got a good chance of increasing in value. By the way, not sure if you’ve disassembled one of these, but there are a lot more teeny tiny parts than the FWB 124. For example, the front sight alone has springs and steel bearings and a punch pin that need to be kept in a good small parts container. The trigger assembly is similar, has several tiny springs and a bearing that is really easy to lose, also an O-ring holding these pieces in place. That O-ring is fragile and broke on me, forcing me to contact FWB Germany to order replacement parts. PITA, have to say it’s not nearly as elegant as the Rekord In terms of serviceability.
I like it better than the rekord triggers. I would actually prefer lower velocity on the FWB sport. My tuned one shoots well but quite strong, to the point where the stock cracked. FWB quoted me ~160 for a new stock. I don't think I will go this route though
Man if I had a Rekord trigger on my 52 .25 I would probably sell everything else except that lefty FWB300 & R1
Agree the trigger feel is good. Wasn’t commenting on that, just design/serviceability. The steel balls associated with the trigger and rear sight are a minuscule 2.5mm (3/32”), and have to be held in place to reassemble. Springs are similarly tiny. Really disappointed in FWB’s engineering choices here, even though I like the gun as a shooter very much.
Thanks Chuck, I didnt realize HW seals fit the FWB Sport?? Never saw that reported previously. No machining required? Snaps on firmly? As for the kit you referenced, I don’t see it, or any PG2 kits on their site anymore, only PG4 kits… Tried searching for your kit number, nothing found?
Have to call and talk directly to Tom for any of the older style kits.
just found your FWB Sport thread with that info, apologies for duplication. That is fantastic news to hear, I’m running experiments with factory seal, ARH sanded-down seal, and factory 28 coil spring vs Pyramid Air 29 coil spring (yes, they claim it’s an FWB replacement part but it’s actually longer). I would much prefer a Vortek moly seal if the “permanent lubrication” concept really works, ordering one today. Any idea where I can find a fitted spring guide?
That would be a CUSTOM part where as the name implies .. FITTED, referring to the fact a replacement spring guide is sized specifically to the springs inner diameter.
Hi Scott, yes understood, need the actual spring for proper fitting. If I ship a spring to you, can you fab the guide? Was also wondering if any expert tuners like yourself considered making guides with fixed diameter, very slightly oversized, that a customer could lightly sand down to fit their individual spring? Similar idea to what JM does with his ARH piston seals. Not sure the pros/cons with that concept.
Short answer, yes. I enjoy tinkering with the inner workings of these guns, puts me in the tiny minority I suppose. I rebuilt my Anschutz 380 in June/July, took nearly two months to get it right but I really enjoyed the challenge and learnings (much of the time was waiting around for parts). The members/experts on here and the other forums are just fantastic.
From my perspective ... To much time invested for too little $$ return. Doing such would prompt more phone calls and time spend furthering the low profit margin of a single task / model part.
No worries, understood! It's a business. Especially appreciative of your work now that I've spent months tuning a few guns (LG 380, FWB 124, FWB Sport).
Thanks, spoke with Tom and have placed an order for a custom kit. Did you self-install your kit? Wondering what your kit looks like (any pictures?). Assume there's a spring guide on the trigger block end, wondering about the piston-end of the spring... Tom noted the Sport has its own top hat built into the piston (which I confirmed) so no top hat will be provided in my kit, only a couple of pre-load washers I can play with on the piston-end. So it's actually closer to a PG1 kit. In fact that's the part number he asked me to use in the order: (PG1-905148-28) with a "No Top Hat" note in parentheses. I went for 28 coils per the original factory spring, and will cut down coils on my own as needed. He remembered you and referenced his notes from working with you on your Sport. That helped move the conversation along much more quickly.
