The barrel should be marked as to what chamber it has, No?


Granted all the barrels / rifles I have like that are carbine length / carbine gas but... They will not digest M193 / 5.56 pressure stuff without protesting and it usually results in an instant death sentence for the brass. (with true .223 match chambers)

Yes, They will send the bullets down range but you definitely know something is not right. LOL!



The spares above got sent off to CLE and Frank rechambered them in CLE .223 match. Those will digest most 5.56 stuff just fine but in stock form with their original .223 chambers - Nope...
