In December of 2006 I bought a Sabre Defense upper from Talon Arms. Since then, I have learned there is a chance the upper receiver might not be manufacturered by SDI. Nevertheless, the barrel is SDI, and it is all I have for the moment. Robert at Talon told me the uppers were not available from SDI with Auto bolt carriers, but he did sell them seperate and would swap out the Semi carrier with an Auto carrier.
The bolt itself is marked with a CM. Please look at the pics and tell me what items I should probably replace. At the very least, I'd like to replace the bolt with a BCM bolt. However, I'm not sure if I should replace the gas key and/or the carrier too. To my untrained eye, the carrier seems fine, and perhaps the gas key would be fine too.
Thanks for the advice and help.
There are other pictures HERE (http://mynetimages.com/album/roymtbkr/firearms/) which you may find useful.
Oh, I almost forgot to mention that I have put over 80 but under 100 rounds through this upper, using the exact bolt carrier group you see. Does the wear seem to match 100 rounds of SAAMI spec .223?
