Xisico does make excellent barrels too. My XS60C rifle, XSP180 pistol, and Browning Leverage underlever (XS46U) are all superb shooters for the reasonnable amount of money they cost. I do have another break barrel rifle, a Canadian Hunter D18 in .22, it's a re-branded BAM (Xisico) XS-B11 and it's also a super nice shooter. Ah, and let's not forget the BAM B4-2 underlever in .22, amazing too! Only gripe I have is against the Xisico plastic sights.I fully agree that SAG airguns are hard to beat, I have 4 QB78 and they're all tack drivers. My .177 and one .22 now have LW barrels (.177 and .25), only because I got very friendly prices on the fully machined and blued barrels. The original barrels were used to re-barrel a couple vintage american airguns, and I'm real glad I did that!

Lillysdad621 and I have a shared fascination with higher caliber, lower power pesters. What might be called a 'garden gun'. (I am amazed at the results British airgunners get with .25 at only 11ish ftlbs.)
Since LW seems to be the gold standard, how did your SAG barrels compare to the LW barrels as far as accuracy and pellet-pickiness?
Where are you buying the xisco model selection listed? Flying Dragon only currently lists 4 models. Is there another good supplier in North America?
Thanks for all the good and timely info!I was speaking with lillysdad621 about qb's with LW barrels just today!Since LW seems to be the gold standard, how did your SAG barrels compare to the LW barrels as far as accuracy and pellet-pickiness?
My .25 LW QB is tuned to shoot a 20.06 grains H&N FTT in the 490s with CO2, just under 11 fpe. With HPA I guess it would shoot in the 12-13ish fpe, never tried it though.

With HPA I guess it would shoot in the 12-13ish fpe, never tried it though.FWIW I've built a few QBs that I've alternated between CO2 and air, and generally find that running on air with a bell curve roughly centered on CO2 pressure will yield at least 50% more energy. That surprised me the first time I ran a back-to-back test. In the following thread I solicited comments and Ribbonstone shared some numbers that aligned with that relationship but admittedly there are a number of variables that could potentially sway the outcome.https://www.gatewaytoairguns.org/GTA/index.php?topic=176104
BSA/Gamo still rules as far as very good barrels on a budget rifle.. but having a blast with my icon... Found my K.O. 13.4g tune for it... power adjuster at .41" in... 3000 929 2800 949 2600 935 2300 919 2100 890sent some CPUM in between the above shots... did a 10.5 2900 psi string 1026 at 2900up to 1040 at shot 3 and stays there till 6th &7th at 1036... then 1038 at shot ten... then the falling string starts...at about 2600 psi...from 1020 down to 968 fps at 20th shot at 2100 psi...4 shot groups cause I have 16 Shots at ~26 fpe with the K.O. 13.43... Dry blurry eyes from new medication or would be a bit better...
Is the Beeman Chief ll a SAG? I am just working up a brand new one, have had the barrel off twice doing barrel band stuff and the barrel looks excellent with my old eyes. Lead is good, crown is good and the rifling is very good looking. have fired maybe 60 pellets so far and the feeding into the lead is very smooth. First 30 shots at 25 Yards shooting shot string through Chronograph.

As good as the LW for that, I could have left the rifles alone .
