Silent Scope Sat Feb 26, 2011 10:00 pm
This breech is very much the same as uin13/ice's breech design he made a while ago, albeit its improvements. My biggest observation was the clever use of keeping the bolt nub connected as one piece with the bolt itself rather than chopping it off and gluing it to a connecting 16mm UPVC/1/2" CPVC equivalent.
One thing I would modify in this breech would be to drill a hole large enough for a metal bar/wire to feed through the nub and utilise that as a dart guide rather than a piece of plastic as to simplify it. Apart from that, besides the incompatibility with streamlines, it seems that this breech is just about ideal in many ways compared to the brass design based on its simplicity and feed reliability (one thing I hate about brass breeches, that's for sure).

Scratch that... I just noticed that it will only feed from clips modified for short stefans. Silent scope was trying to make it take stock length dart.
My conduit breech is rather different, taking design merits from the Angel Breech layout.
I will say for the record that I have tried to adopt this style breech with the ability to accept longer darts. Just like brass breeches, the amount of effort to ensure proper sealing requires 100% attention to measurements nothing out beyond the mm in variance. So far I haven't been able to pull it off as a result. Though it doesn't seem out of the question if
nihil413 has been able to pull off something similar in concept...
Anyway Brad, you've given me motivation to get cracking with making one streamline compatible. Keep up the excellent work.
