Everyone asks where I find AR-15 stuff in stock or where I order from, so here you are: [ Ссылка ]

The KNS Precision non-rotating pins are a very quick, but excellent upgrade for your AR-15/M16 style rifle. I show you exactly how to install them in this video. There is plenty of clearance to use accessories such as the Troy Ind. Ambi Bolt Release or the Magpul BAD Lever.

The type of pins I used in this video are labeled as: Gen 2 Mod 2 Non-Rotating Pins.

**INFO FOR PEOPLE WANTING TO USE THESE ON GEISSELE TRIGGERS**

"Here is the deal on non-rotating pins

Geissele SSA pins are 0.1550" dia +/-0.0001
Holes in the trigger can be 5 tenths over Geissele pin size
Kns pins are either .154 or .1555. So they are either too loose or just about a metal to metal fit in our triggers

Geissele pins are chrome-moly steel that is rough turned, rough ground, heat treated and then centerless finish ground. They are a quality pin.

Why do we not recommend KNS pins? One is that they are the wrong size. Can the smaller diameter pins work? Yes, but they are not the intended size and there can be a 'softer" break to the 2nd stage with them.

But the biggest reason is that the KNS pins are soft. Sometimes when they are installed they pull up a burr that causes havoc with trigger operation. I get calls from frustrated customers where they are totally disappointed in their SSA because it either feels terrible or it hangs up. I spend all kinds of time on the phone wracking my brain trying to figure out what is going on and trying to work the customer through the problem. Finally, I ask the customer to send the trigger in (which I hate to inconvenience the customer with) and the issue is that the KNS pins are jamming the trigger up."
