I picked up a new with no box or instructions DD Lite 12.0 FSPM,
What is the barrel nut torque ??????????( I have their wrench) What are the attaching screws tightened to??? just criss cross or is there a special procedure. When re-installing the taper pins, Do you just support the barrel end since you can't put the FSB in a fixture??? I installed a few of the old 12.0FSP with the horrendous gap at the FSB a long time ago and can't remember if I did anything special for the taper pins. Anybody care to p/m or email me the instructions would be GREATLY appreciated so I can file it away. |
| Shoot me an email and I'll reply with a PDF Copy of the installation instructions. The barrel nut is to be torqued to 50 ft/lbs. The screws need to be tightened in a criss cross pattern and have a torqe value of 29-32 in/lbs. When reinstalling the taper pins, you will need to support the barrel. I typically keep the upper in an upper reciever vice block and rest the barrel on a front sight block. |
