Most Helpful Positive Review Pins Are Compatible with LR308
Pins are compatible with LR308. There was a run of another manufacturers lowers that were out of spec that did not allow our pins to work. The pin hole on them was smaller than the manufacturer stated they were supposed to be. We also had a customer measure the pin holes on their lower that was supp...

Most Helpful Negative Review To large of a diameter

According to several sources "standard" AR10 pins are equivalent to a .278 gauge pin. While of high q...

Yes and However...

by John, Verified Owner from LA, United States Written on August 11, 2022
For the detent to engage the pivot pin on my LR-308 the Armament pin head thickness had to be reduced. I found this out the hard way after installing the pivot pin and trying to depress an out of alignment detent to remove the pivot pin. Because the slot in the rear takedown pin is turned downward on the LR-308 and adds play I used a round KNS .278" diameter push button pin instead. Building a .308 includes extra work and hidden expenses.
Pros:
  • Quality material.
Cons:
  • May require fitting.
Would recommend: Yes

WILL NOT FIT AERO M5E1

by Big B, Verified Owner from AR, United States Written on April 15, 2019
These are too large of diameter to fit in the Aero Precision M5E1 and even though they are very well made; they unfortunately will not be of use to me. The kns shift pins seem to fit however, but I do not like the way those come completely out and are not captive like these are

Does not fit LR308

by Douglas, from TX, United States Written on August 2, 2018
Just received these. They are advertised as being LR308 compatible. Attempted to install them on an Aero Precision LR308 upper. They are oversized and do not fit. Beautifal part but have to return it.
Pros:
  • Beautiful part
Cons:
  • does not fit
Would recommend: No
