Another AR-15 noob

From first hand experience iv seen trigger pins walk out. My brother has a spikes tactical lower and trigger and the reset pin walked out from time to time. I was told by a former marine that he would recommend them. I'd take advice from someone that actually saw combat and personally uses them on all his rifles. Their like 15 bucks. If you can't afford a $15 part then your doing something wrong in life.

 

Also my cmc trigger works fine with KNS and they advertise with and without them on thier rifles

 

Two things: 1) if you use quality parts (I personally will never own any of the garbage Spikes makes) and install them correctly it will never be an issue and 2) your buddy the Marine who saw combat was firing either one M4 (likely) or an M16 so we're not talking about a SA AR15 we're talking about a FA M4/M16 which is what they were designed for. Of course you would use them on one of those. Two totally different beasts. I never said I couldn't afford $15 so don't make assumptions that make you look silly. Just because it's cheap or you can afford it doesn't mean it belongs on your rifle. The very fact that you use them on a CMC trigger proves my point... unlike the stock or other aftermarket trigger groups the CMC FCG doesn't rely on the pins as a rigid mounting point by which to function as it's self contained. They don't roll around against the pins or do anything that would cause them to 'walk' out anyway. But, it's your rifle so do what you like.

 

My buddy wasn't able to take home his service weapons and yes he most definitely used a M16/M4. Got the cmc trigger for my carbine at a swap meet, spent $50 and a handgaurd lol. I do use the rock river arms national match two-stage trigger on my other three rifles. Out of 6 ar's I have only one with the cmc trigger. I have my complaints about it, definitely is not as good of quality, it did wiggle slightly inside the lower. That's why I put the anti walk pins. But the cmc has 0 creep and the reset is smooth and audible. I got rid of the wiggle by putting tape under the rear of the housing until it had to be compressed with a few pounds of force before the trigger pin could get through. Anyways ak47s are so much cooler than ar15s. And a hell of a lot more reliable. I don't think I ever cleaned my Wasr-10 with over 1000 rounds throught it. Only a quick barrel clean every once in a while.. I shoot my knights armorment ar when I'm shooting 300 plus yards, it's a tac driver. Everyone has there own personal opinions on things, like you said it's your rifle. No one has to be a dick we are just trying to help fellow Americans build a rifle that won't give him problems when Isis comes lmao

 

I'm not being a dick. Just stating facts in an effort to 'help fellow Americans build a rifle that won't give him problems when Isis comes' like you said. You chose to see that as some sort of a personal attack for reasons known only to you.

 

KNS pins aren't necessary when trigger and hammer pins are installed correctly and everything is in spec... But they certainly do not hurt anything and if you have 2k+ into arifle, throwing another $30 at it is a drop in the bucket.

fwiw- I have yet to have standard fcg pins walk, but I do like the KNS pins and therefore I add them on as cheap insurance.

 

You keep bringing up cost and I assure you this has NOTHING to do with cost. Nothing. At all.

FWIW, I also don't personally know a single person who was in combat that used KNS pins because they make servicing your rifle in the field a tremendous pain in the ass. That's people using FA weapons that are more likely to have a trigger pin walk and they don't even use them. To say they don't hurt anything (especially if you care about the finish if the outside of your lower receiver) is false if you care about servicing your rifle which anyone who owns an AR15 should. Honestly, you just end up looking like some internet commando with all that whiz-bang crap on your rifle that does nothing to make it high speed and low drag. Buy a basic built rifle from a trusted builder, a boat load of ammo and some training classes. Then, once you have enough trigger time to know what you like or don't like, start changing out parts. If you can't see a benefit to you personally don't buy it. If you buy something thinking it will be of benefit and you find out it isn't, pull that shit off. Every single part on the system has some 'improvement' that costs about 3-4x more and most don't do anything other than add another failure part or weight.

Your rifle. Do what you like. Just don't come at me when I'm the voice of reason.

 

No definitely do not put them on service rifles lol. That would be a hastle in the feild

 

Look man. Idc if you don't use them or you do... ar15 forums is where I read about guys using them on service rifles from ppl that actually use their rifles on an everyday baises to ppl that don't. There are really good write ups about them at ar15.com

 

That forum is mostly internet commandos & other assorted idiots who don't even own half the shit they claim let alone have first-hand experience shooting it. I checked it out like 15 years ago and it's only gotten worse since. I'll pass but thanks for the tip.

 

That forum is mostly cops and military. I guess you didn't have access to that part of the forum? is it that hippy socialist shit rubbing off on you there in Colorado.. you just come off as a prick. That state used to be cool. Wtf happened to it

 

ROFL

No, it isn't and no, I'm not.

 

Hahahaha I kid, but yeah there's a section just for military and law enforcement on that forum. You would need to be invited to that section as a civilian.

 

There anti rotation pins, they stop the hammer pin from rotating. Years of the pin rotating will cause wear.

 

What isn't on your rifle? Anti rotation pins? That's because they are not necessary. Eugene Morrison Stoner would have had them installed if they were needed. The rifle went through 50+ years of little tweaks and changes to make the platform more reliable

 

I agree 100%.. the design of the rifle doesn't need them AT ALL. I only have them installed on one of my rifles. That's because I have a drop in trigger installed

 

Does anyone have experience in building an ar10? That's what I want to do next. Iv been reading a little about it and I found that parts aren't like the ar15 in a way that nothing part wise is really mil-spec.
