Tuning Impact. Barrel to Maverick

The barrels and liners are the same so should change over just fine but the shrouds are not so you may or may not have problems there.

The 250 bar bottles can just have a sleeve installed over the valve pin and they will werq on either gun. Although the newest M3 guns have a new style first reg, with more threads, for 300 bar compatibility so not sure if they will still fit older bottles. Or if the new 300 bar bottles will fit on the older 250bar guns. 

I’d give top airguns a call on bottles as he put 300 bar bottles on a maverick so he could probably give the best info on that. Airtak hunting on youtube did a vid not too long ago where he had a impact barrel on a maverick i think and listed a print for an extension for the shroud so it would fit properly. Hope this helps!

The Impact shroud will work with the Maverick but the Maverick shroud won't work with the impact. And as far as top airguns I would wait because the valve they sent with the 300bar bottle was wrong and caused the bonded washer to shred. I called and spoke to them last week and they are aware of the issue as others have had issues with just putting the sleeve on the 250bar bottle valve adapter. Ohio Airguns and Talon Tunes are both selling the correct bottle valve adapter which is fully threaded for the 300bar bottles.

I was told by Top Airguns that the bottle valve adapters they installed on their 300bar bottles was sent by FX but now they are awaiting a new shipment of bottle valve adapters from them. I also asked what they were doing for those that had already purchased and were given the wrong adapter and they didn't have a response and just said they didn't have the right one as of yet.

I'm guessing the older bottle valve adapter with the new piece installed should work with the 250bar bottles but I'm not sure on that. I just purchased the entire bottle valve adapter to make sure instead of trying to make the older ones work with the newer Impact requirements. Also, the new bottle valve adapters are backwards compatible with the Dreamline, and Impact MK2 as well. I'm just not using the 300bar bottles on those because they don't have 2 regulators like the Maverick and the M3.
