I am diving into the PCC pool

Recommended Posts

You had me nervous for a second, and I had to read it again, I thought maybe you were saying it is a comercial sized tube.

 

Yes, thanks, I do know the difference, and didnt have to learn the hard way!

 

I definitely appreciate the heads up!

lol.

I am really looking hard at using the longer type tube, because I often feel like many of them are just too short to get comfortable.

I am always double checking to see if the stock is pulled all the way out.

 

Plus having all that extra room on the inside to fine tune the buffer set up is definitely a nice bonus.

 

So, you can make a delrin spacer the length of the difference between the A5 and carbine tubes and use standard buffers, or you can build a longer buffer system to suit the new A5 tube...  Good plan!

 

What buffer system are you planning to start with?

I have the blitzkrieg 9mm buffer, and a stack of wave springs.

I will work something out!

 

I will probably start with just the blitzkrieg and a 308 spring, in a standard length tube, as a base line, then go from there.

I guess I need something like this

This vltor tube ????

The vltor is on its way!

I found one at MidwayUSA 

(It seemed to be Out of stock, everywhere else I looked)

Tracking info says it will get here Saturday.

I am going to try and build it on Sunday.

I hope it makes it in time!

I know it's too late for the OP but, as an FYI Palmetto State AR10  buffer tube  is the same length as the Vltor A5 and at least $10 cheaper.

Good to know, I will need another later on!

It got here on Fri.

 

We build this afternoon, after I get off work!

It's been I long wait, and I am kind of excited.

Here is what I am starting with, I will at least change the furniture, maybe the optic etc.20180729_182229-1-1.thumb.jpg.fff9331c1a2d8aa7bb2b8f7d652f6e4f.jpg

Good start! 

 

I can’t say enough about how happy I am with the Holosun 510C by the way.

 

Let us know how your buffer/spring tuning goes.

I am starting out with a 308 carbine spring with quarters taking up the rest of the difference in the A5 tube.

 

We ran 2 mags through it, and it ran fine.

 

I will play with it for a while  (sighting it in, etc.)

Maybe a couple local league matches, before I start messing with the the 223 spring or the wave springs etc.

What buffer, @Startingover?

 

Does your carrier have the weight in it?

It's the 9mm blitzkrieg buffer

Faxon BCG - just the way it came out of the package.

 

I don't remember the total weight off the top of my head, but I think it was pretty good

Glad you got it together and shot it...  Great looking rifle!

 

Did you go with the Vltor A5 extension tube for the longer reach (length of pull) or because you wanted to experiment with different length buffer setups?

 

Would be nice if someone started making delrin buffer spacers.

Both reasons.

I could have found a longer stock to fit on a carbine length tube, but that's a pain, so now I can use any stock.

But I really wanted the extra room for playing with the buffer.

So the increased length of the A5 tube gives you extra room for a wave spring and delrin spacer?

 

To calculate the length of the delrin spacer:  Take the collapsed length of the wave spring and subtract that from the increased length of the A5 tube to get your starting point for the delrin spacer...  If that all works out, increase the length of the delrin spacer to short stroke the bolt.

 

Does that sound about right?  Been trying to figure this out for a while...  I think I might be getting close.

Take a roll of quarters to the range and see what makes the gun shoot flattest.

 

See how many allow you to lock the bolt back, or your LRBHO to function if equipped. This will probably be a diffent number from the first stack of quarters.

 

Take those things, and decide how much of a stack you want to run behind the wave spring. A single quarter still stays on top of the wave spring for the buffer to run into, of course.

 

Once you’ve run it that way for a few matches, consider making a spacer out of some delrin if you feel like doing so. But quarters are impossible to beat for calibration purposes.

As stated above, remember to put a quarter (spacer once you get it figured out) between the regular spring and the wave spring.

Start with quarters so you can make lots of adjustments.

When you get it how you like it, measuring the stack of quarters will give you the spacer size.

You mean like a genuine Colt spacer to be used with a carbine buffer tube and a 5.56 size (3.25") buffer?  Here you go:

 

Colt 9mm receiver extension spacer

Good tips, thanks...  I don't lock the bolt back or use the LRBHO linkage, so that doesn't matter to me.

 

I assume you are using the Blitzkrieg hydraulic buffer?
