Which pin diameter to buy or what to check in the frame to know the KNS pin to get?

from KNS:

Sizes: Small .154 dia.; Small .1555 dia.; Large .170 dia. These are the Generation 2 Mod 2 pin sets. They are the STRONGEST pins that can be produced and were designed to withstand the high impact of full and semi-automatic 9mm and .223 suppressed weapons. Stainless steel pins. End retainers are black oxide, dark earth, or OD green. An absolute must-have for all M-16 owners. They will also protect your AR-15. Special anti-creep retainers prevent wear on your irreplaceable M-16 or AR-15 receiver. Pin installation tool & 2 Allen wrenches included. No modification to gun required. The .1555 dia. pin is for worn receiver trigger and hammer pin holes. Being non-rotational, further wear is eliminated. They will also fit new receivers and will remove the free-play in match triggers. The .1555 will not fit Jewell Trigger System. The .170 size fits late model Colts. For Rock River National Match triggers use the .1555 only.

Right there is your answer. Unless you have a large pin Colt receiver then .154 is probably what you want.

I installed the .154 size in a new Mega Machine receiver and have no play. With the screws and "struts" connecting the two pins, I would not think you need the .155 pins in a relatively unworn lower to prevent play between pins and receiver holes
