according to jl billet that ambi pin's length is 0.5"L which doesn't allow enough right side lever movement to shove the bolt stop FULLY into place. Grinding it to 0.47" allows correct travel to fully engage the bolt stop from the right side AND more importantly the empty magazine traveler to also shove the bolt stop into full engagement. Why their engineers have not dealt with this I don't know. Possibly they have changed dimensions in the width of their newer sets since I acquired mine. (made the pin's tunnel longer or deeper) but I doubt it. The pins diameter is approx. 0.153" made a few from drill bit stock

can't locate a replacement for a JL Billet 308 lower receiver's ambidextrous bolt catch pin. Can anyone tell me what the exact length dimension is for this part? The diameter is 0.154", the length is approx. 0.813" but it must be exact as possible. Have the spring. The ambi set came from JL Billet. Excellent workmanship. thanks
