G'Day Fella's,

Just on the Rem 7600 rifle for a moment.
Among other things, www.lumleyarms.com (located in Sydney Oz) have advertised on their web page, spare Rem 7600 barrel brackets/barrel extensions for 7600 rifles!
This will give any 7600 owner, the ability to make you 7600 into a Switch Barrel rifle!
That is, with any cartridge with the same bolt head (.243/.260/.308/.338Fed etc or .25-06/.270/.280/.30-06/.35W/.9.3x62 etc or .223/.300 Whisper, etc)!

Just a bit of an insight into the quality of their other products. I have two Lumley Arms 316S/S DBM (Detachable Box Magazine/Bottom Metal) units (for Rem 700) and they are exceedingly well designed and made and work flawlessly!!!

Hope that helps

Doh!
