    True that.

To say they'll be harder to take apart in the field??? I doubt the vast majority, 99.9% of ALL the rifles on this or any gun board will ever see past a range or at most a training class.

    Ditto.

    It's apparent that you have this site confused with some others. Our users aren't typical of most gun owners that I have run in to in the last 15 years.

    If they don't do any good, then it is a waste of money.

    I have an issue with all of these things that you mention. I won't use them due to concerns about reliability, as well as concerns about the added complication in field repairs.

    If anti-walk pins actually prevented issues, I could understand the use of them, but I don't see what they do for the weapon, other than to add more complication.

    This is true. I have never seen a pin walk out. It could happen. The only tome I've even heard about it is in fa with a gun that should have been a paperweight anyway.

    That being said, I have used them. Didn't see any improvement, but the psych was there from my "buddy" talking shit. Have sense removed them. They set in the parts bin waiting for another project. Maybe shrike? Hehehe

    Who cares if these lower receiver ornaments are as worthless as tits on a boar...they flat out look badass!

    KNS pins gaining value in M4C's eyes...those Mayan Bastards might be right about 2012

    It's cheap insurance. I put them on my SBR lower since I'm married to this lower, I'll take any precautions I can get.

    They're window dressing in most applications. When using cassette triggers (like many drop-ins) they are better than e-clips and wonky pins (seen many of those fail).

    In regards to failing in the field, two things:
    1) Use loctite.
    2) Any screw--any screw (on rail systems, light mounts etcetera) should be marked with a paint pen so any rotation can be easily visibly confirmed without tools.

    8.7k rounds through one of my rifles with no loosening. Of course', I practice the above.

    Had pin walk on a .308 lower. The "J" spring or whatever the hell you call it was not doing it's job in keeping the trigger pin from walking. Although the gun worked, I didn't like that after 300 rds, the pin would literally stick half-way out of the receiver.

    Stuck KNS pins on there, stopped pin walk. Loc-tite on walking pins doesn't work. Probably could have called the manuf. to get a new hammer and J spring. But the KNS pins work.

    $30 is about 100rds of ammo. If the KNS pins work for you, great, if your pins aren't exhibiting any walk, just use the factory pins and drive on.

    IMHO the only down side really is cost--in my limited experience, I've only heard of ONE trigger pin breaking (thus necessitating field repairs). Such parts wear is pretty rare IMHO.
