    The 8mm Inglis Bren talk has thrown a kink into the conversation, can TactAdv show up a picture of the chamber end of his SA barrel?

    There have been 3 different recent conversations which seem to have confused the waters:

    - The L4 7.62mm series used 8mm Inglis Bren bolts & headspacing locking shoulders, so an L4 Bren barrel should lock into and headspace in a 8mm Inglis Bren assuming the use of the ZB26/30 8mm magazine.

    - The "Government" SA 7.62 conversion used a modified .303 bolt (reducing ring silver soldered onto the face of the breech bolt) with a 7.62 extractor. the .303 bolt allowed them to continue the use of .303 locking shoulders. The barrels chamber end is contoured as a .303 barrel (if I understand correctly) to allow the use of the .303 bolt. The magazine well is altered to accept metric FN mags, and an ejector block fitted with a hold open was fitted.

    - .303 barrels have been bored out and rechambered to 8mm Mauser, these barrels use un-modified .303 bolts which are fitted with 8mm Mauser extractors, newer condition Brens require some opening up of the rear of the magazine recess to accept 8mm ZB26/30 type magazines. This type of conversion "may have been" originally done at the behest of an unknown government user.

    - current civilian owners of working Brens have mixed barrels, bolts and magazines in order to obtain guns which function in a variety of calibers (8mm Mauser, 7.62x54r, 8x56r(Austrian/Bulgarian/Hungarianicon), 7.62NATO, .303 Britishicon) which are available to owners...

    As far as I can tell, the 8mm extractor is the same as the 7.62 extractor....certainly much closer certainly than a .303 extractor..
