We patterned our AR-308 to take a standard AR-15 LPK. The only other parts required are these longer pins, and instantly, you have an AR-308 LPK. TN Arms AR-308 Lowers are designed to use the standard roll pin that is used in the AR-15 LPK where as with some metal lowers a screw for the bolt catch may be necessary.
They are made of alloy steel and have a black melonite finish.

They are what simple and appear well made - easily / perfectly fit my TAC AR308 lower.
What's not to like, they're extra long pivot pins that fit this beastly 308 lower. They are made from metal and appear to be quite good at allowing things to pivot on them. I'd say that's a home run.
Great Price! Quick Shipping! Installed with no fuss on the TN Arms 308! Great that you don't need any other 308 specific parts for their 308 Lower receivers!
These pins are perfect for an 80% polymer lower. The pivot (front) pin is about .050 short of sticking out, but easily pushed out with a bullet point and you almost never take that one out. The rear pin sticks about about .050 and is easily pushed out with your fingertip.
Perfect for what I needed. Excellent finish, fast shipping.
