Grouse, if you think the Triumph speed BP is high then price the Endeavor speed BP the only difference is the cut out for the 209 extractor and the price.
Sabotloader, well I did the Triumph and you have done the Omega I will be doing the Endeavor as soon as the plug on mine shows much wear.
Did you notice any thing in particular while the machining was going on? I did and I was not a bit thrilled by it.
Do you think all or most breach plugs are adaptable to this conversion?
