It is very easy to make any airgun shoot arrows well, "I" am still thinking the aluminum ( hey I'm old) shafts slide over a "barrel": is the was the go, like swivelmachineworks used.
Mcmaster has the correct SS thin tubbing to fit Easton aluminum shafts, then you just need a short section of barrel to fit receiver to SStube. Actually a fairly loose fit is good then apply 1-2 drops 20wt ( or?) silicone oil to end of "barrel" before slipping full 18" bolt/arrow over it.
Like crosmans latest except you can convert any airgun ( with room between barrel/receiver) for well under $50.00. A 40fpe .22 rifle swapped over this way, will hit aprox 300fps and with NO flex they are darn accurate.
