Ok, this was always a part I didn't want to hassle with. I've been on the forum for maybe 3 years now or more, and I can only think of seeing about 4 threads for broken BCE or whatever you want to call it. To me that meant it isn't a common part to fail, especially since one had a Tapco MIM in there, and the other had a one off made for the small shop.
Now the new rules come in and my previously compliant builds won't be compliant with my five rounders. I want to keep my pretty wood, so this is the last easily changeable part. (except the temporary Saw grip which needs to go.)
