Is there an aftermarket Hop Up Bucking for the M93R II that can handle Propane/oil instead of Green Gas.

My Stock Bucking seems to be swelled due to my using Propane( green gas near impossible to get hold of here) plus propane is much ,much cheaper.

Ive googled but can find no info on an aftermarket Bucking,can anyone help?

To my knowledge there are no aftermarket hop up buckings that are made specifically for the M93R. You could try a Falcon blue hop up bucking made for the MP7 (which claims it is more propane tolerant, and less prone to swelling), but there's no guarantee that it will fit the M93r...

Im trying to up the FPS on the M93R as its a fun gun/plinker not for playing.

Will this Falcon 6.03 Barrel fit?,its made for the KSC mp7,I know the length will be fine but Im wondering if the barrel will fit in the hop up unit etc.

A+ has a compatible bucking iirc. The problem with hop up swelling is not propane. It is excessive use of silicone oil. I had the same issue with 2 of my 93r and i never used propane. I did however overzealously lubed it causing silicone oil to get into the bucking. The rubber itself is very spongy and swells up pretty easily. Now i just use a cotton bud to oil the rails and friction surfaces only.  I also try to avoid over lubing the mags as they will spew that oil into the hop rubber.

That's correct Tool. It isn't the propane that swells the hop up bucking, it's the excess silicon oil. But remember, green gas has silicon oil mixed in as well, as it helps lubricate all the necessary rubber parts, including the hop up bucking, ensuring it doesn't shrink, and ensures a tight seal with the right amount of lubrication on every shot. Any excess silicon oil will swell rubber parts and may cause the gun to function improperly.
