  1. If you lengthen the moment arm, you need to reduce the reading proportionally. M=Fx, where M=torque, F=force, and x=distance from the point of torque. To correct for a longer arm, M1/x1 = M2/x2, or M2=M1*x2/x1. Where M1 = reading, M2 = desired torque, x2=new distance (both wrenches), and x1 = original torque wrench length. In your video, you're probably applying double the desired torque. Unless you are mentally correcting the reading for the additional length on the fly (right).

  2. What bothers me about so many triggers is that they are way over priced. I was a machinist for over 40 years and I know how this stuff is made. 250.00 dollar trigger can be made for less than 25.00 each. I can see the cost of billet receivers but the small parts is where they make their money. Even so I recommend building your own because it is still less expensive. Most of what you pay for are cosmetics. Spend your money on the best barrel that you can afford and the best bolt carrier group that you can afford. If you watch your money you can build an excellent AR for around 850.00 plus optics.

  3. hi do you build these for money brice told me to ask , but no one called me back. I have all parts already. I can pay to ship it out .and pay for your labor. the lower is in my name already.

  4. you are suppose to cut 4 to 5 coils off the take down pin spring for the seekins lower. I use to work at seekins and I was the machine operator that made the lowers and uppers. along with every other product they make.

  5. If you're going to have a 5.56mm gun that long you might as well go with a 16" .308 like the HK MR762. Isn't the point of an SPR to have a lightweight compact and accurate rifle.
