If I understand what you're asking, it's in my head, lol. If you're asking where the hole is drilled, I'm assuming the hole (aka the base of the wall) is drilled in the same location regardless if it were perpendicular or at an angle. The edge of the hole closest to the buffer is the stopping point (the shortest distance).

You're right, not easier to drill a 6* hole, just necessary to clear the top of the receiver. As a machinist you'd know that finding a right angle tool and bit that would fit in that space may prove impossible. Let me explain it another way. Say you've got a wall and you slide your shoe along the floor until it meets the wall. Regardless if that wall is plum or at an angle sloping away, your foot is going to stop at the same location. In this example the wall represents the pin and the shoe represents the head of the buffer. Unless that shoe rides up the wall, which is possible depending upon tolerances, it's going to stop at the exact same location. We could do the math of worst case scenario, given that some how due to slop the first point of contact on the face of that buffer tube was the very end of the pin. Unfortunately, I'm not good enough with a computer to draw it up and post it here but all you'd have to do is measure how far the pin extends, draw a right angle triangle with a 6* corner and solve the lengths of the other sides. We're talking a few mm at most. Not enough to make a difference. This is pure speculation on everyone's part but one logical reason to drill the hole at an angle has been provided. To backup your position you'd need to provide a different, functional need.

I'm with Survival on this one. The stopping point is the closest point to the buffer head, which is the same regardless if the hole is vertical or off 6 degrees. The difference is at the 6 degree angle the top of the pin would slope outward away from the face of the buffer instead of parallel to it. This is all in theory though, in a perfect world without tolerance variances. Account for the play in the hole & pin, between the buffer & tube, shape and angle of the buffer head, ect and there's a lot of play in the system. Even so, you're probably talking tens or thousandths of an inch in difference, in other words, not enough to make an operational difference. It's most likely drilled at an angle purely due to ease of manufacturing.

I'm only a pain in the ass to you. And I"m ok with that. Talk it up. Most of those very specific questions still haven't been addressed, let alone answered here. You've got a lot to do with that considering you'd rather talk poop then address them.

You know, before I ever posted, I knew you were going to be a problem. I saw the way you treated other people in other threads and I was reluctant to even post because of it. I tried to tread lightly with you, even suggesting discussing thing in PM so the thread could stay on topic and keep this out of the public light so as not to embarrass you, but that wasn't good enough for you. You insisted to air it out in public, so here you go. I hope you're happy. You're an center of uranus, who's looking for a fight because he's got low self esteem and tries to make himself feel better by degrading other people. Well, sorry, I'm not some young dumb kid that can be pushed around and doesn't see who you are and what you're doing. You may be knowledgeable about 308 AR;s but that doesn't give you the right to treat others like poop and you shouldn't get so butt hurt if someone doesn't take your advice. Your manhood is not determined by whether obeys your command or not. You need to do some serious self reflecting, I'd suggest counseling or a good mentor.

As stated in the first post, the receiver set is paid for and on order. I've got some other small parts but the parts that really determine how the rifle functions, the BCG, barrel and buffe system are what I'm trying to finalize. The biggest issue right now is trying to find them but as soon as I lock down which specific parts I want I'll order them, even if it takes several months to get. I've got the money now and want to spend it.

Thank you. I think my first post was pretty specific about the questions I had and you're actually attempting to answer them. I'm not really sure how people got so hung up on criticizing hydraulic buffer systems. I was never interested in them in the first place for the build, just curious why they weren't more common, learn more about them, and get other perspectives. The captured spring systems, yes, but nothing else. The Armalite setup is the most reliable over the broadest range, if you go another direction there are going to be sacrifices. I get it, it makes sense, I believe it. If I choose to try something else, I now know the risks and I appreciate the advice. That was my main question about going to a lighter BCG, if you have to add weight to the buffer it kind of defeats the purpose. Do you have any idea what weight buffer would be needed, say with the longer Armalite style buffer tube?

I don't doubt experience, but no, this forum is not any different then any other on the internet. It's impossible to escape that. I'd say about 90-95% of what you read online is false, or misleading at best. Seeing what's recommended in forums and even in the media in industries I'm a knowledgeable professional in taught me that much, 20 years ago. That's the problem with trying to get advice online, you have to wade through a lot of crap to get to the truth. I'll take the advice from the experts & the manufacturers long before something I read online. That's not to say there isn't a lot of good information online and likely this site included, it's just you have to be able to identify the bullpoopy and that's not always easy to do.

Agreed. And this conversation has nothing to do with the topic. If you'd like to discuss it we can in PM or by other means as my PM suggested.

Alright. I messaged you privately but if you want to hash it out right here I will. Just confirm that what I say will remain public and you will not make sure to ban me because of it.

As if you are the God knowing all of the internet. Sorry, this is the bathroom wall of society, I take everything I read or see with a grain of salt. You have to prove yourself to me just like anybody on youtube. I don't easily recommend any forum, channel, ect. You have to prove to me that you know enough that I'm willing to recommend you. This forum and it's members are not the end all authority, nor am I.

So here's where I'm coming from. When you said that the Armalite kit IS the buffer solution, hands down, game over...I agreed. You sold me, I got it, I believe you, I don't doubt you. And from there, I moved on to trying to better understand the application that is the 308-AR. I'm new to building guns. Actually started out wanting to buy a 1911 and ended up building an AR, because I couldn't find the 1911 that I wanted and ended up building an AR, lol. I want to learn, so don't mistake my questioning your advice with not understanding and taking it. If I have further questions though, I'm not the type of person to hold back.

Thank you, That makes a lot of sense. I've been turning to the Youtube channel: SmallArmsSolutions as a resource and that adds a perspective to the issue concerning hydraulic buffers that he didn't mention. As far as the TI BCG, my understanding was you may need to add weight to the buffer to compensate for it. I may be remembering this incorrectly, being that I did the research before building my AR-15. And that was my concern, no point in spending a bunch of money to lighten the BCG if you have to add some of that weight back to the buffer in compensation. That's one of the main reasons why I'm looking into other buffers.

I feel like you're baiting me. I'm not sure what you want me to say. It' pretty simple. There are various spring rates and buffer weights depending upon application. The ammo you use, barrel, length and style, gas system, bolt carrier group and weight, buffer tube length, silencers, all effect what spring and buffer you need to use. The buffers are pretty simple using a number of steel or tungsten weights inside to determine the weight. Their properties of the buffer work sort of like a dead blow hammer, but I'd still like to know the theory behind why the engineers thought that was necessary or the best solution. I'm guessing that the physics suggest that you need x amount of mass to slow down the energy created by the explosion in front of the BCG, but I also think this could be accomplished by using a shock absorber (for example) instead of a dead weight. Which brings me back to my original question about what the suggested buffer weight difference is between using a standard or titanium BCG?
