I am diving into the PCC pool

Interesting.

 

I need to measure mine every 500 rds to develop a replacement schedule.  Hopefully it slows down after a while.

 

Thanks.

 

 

I am thinking they will settle to a point, and stay there for a while.

 

I will casually start looking for a similar replacement, that might last a little longer.

 

But I have extra room in my tube to play with.

I've started testing a Blitkrieg buffer with a 95# spring weight / 25# load wave spring. 

 

Also took delivery yesterday of some 67# spring weight / 18# load wave springs to see if there is any improvement with dot movement.  These are .875" diameter.  Someone mentioned the quarters used for spacers were getting stuck in the 1" OD wave springs.  Thought a smaller diameter spring might be better.  (They are also a bit shorter than the first set of springs.)

Cool Stuff 

Keep us informed on the process.

I had the problem with the quarters getting tangled in the wave spring... 

 

I was at the range and kept adding quarters and shooting to see if it improved things...  I stopped adding quarters after I passed the bolt lock-back position...  It seemed to shoot better and better as I added quarters...  when I got home I dumped the quarters and wave spring out so I could measure them and found that the wave spring was binding on the buffer tube...  one of the quarters seemed to have slipped under one of the wave spring rings and bent it...  I replaced all the quarters and wave spring with a delrin spacer of the same length.

New Taccom barrel on the way.

Shorter handguard is needed now.

I have a brand new 9" Brigand Arms carbon fiber if you are looking for light weight.  PM me for a great price.

If it was a 12" I would be all over it.

But 9" is a little shorter than what I want.

Yeah I feel you.  If it was 12" it would be on a build already. Would be great for an SBR though.

New tension barrel just showed up.

Looks like a nice piece, and passed the plunk test (within reason anyway)

[Startingover]

New 12.5" Odin Works forearm cover on they way.

 

Found it for pretty cheap

That looks nice; super light

[Startingover]

I just did some fuzzy math based on website specs.

 

By switching out my Rainer Arms barrel with vg6 brake, and 15" Atlas-S handguard , and replacing them with the new Taccom tension barrel (with their pinned and welded comp), and the 12.5" Odin Works handguard , I will be dropping 19.1 oz. off the front of the gun!

 

We will see what the scale says when done, but that's a lot of weight!

Should be interesting.

Mbx PCC or jp? If you want ready out of the box and are ready to spend for either?

[Startingover]

Just got a 2nd upper from Jones Arms yesterday.

I was looking for another Odin Works, but they were all out of the ones they had coated, so the sold me one of their very first ones they machined.

 

I think I will move the Rainer Arms barrel and Atlas-S handguard on the Jones upper, and put the new Taccom tension barrel and Odin Works handguard on the Odin Works upper.

 

 

What upper vise block does everyone use?

 

Having a hard time finding the DMPS one in stock.

I see Odin makes an aluminum one.

For forged receivers I use the ProMag vise block below:

However, for my side-charging uppers I use a small block of wood on each side of the upper inside my vise. That works well enough for changing barrels, etc.

I use the DPMS one from Midway...  It works well, but they are also out of stock at the moment.

 

Haven't found a nice lower vise block for 9mm Glock lowers...  Sacrificed an old Glock magazine and clamped it into the vise...  Not perfect, but better than nothing...

Nobody has shot the mbx PCC?

There is a lot of info here if you try the search feature, I don't know enough about either of them to say.

I would recommend a Jones Arms Kronos 

[RadarLuv]

That's great advice thanks

Never could find that one anywhere, so I went with This Odin Works from Rainier Arms now I can get to switching stuff around.

 

I also picked up a battle arms safety switch and Ti pins for the next lower build, whenever I can afford another trigger.

 

I just realized the other day that I will need a second optic for this second upper.

(I guess I will put my 3x vortex on the 16" long barreled one for now)

 

Where does it end LOL?

Looks like a nice block...  Wasn't available when I bought mine years ago...

 

I have a second upper and lower, too...  The expensive part is the sight for the upper and the trigger for the lower.

 

I'll probably buy a second, spare bolt before I put together a second upper...  although I really like the 13.5" Taccom barrel that you got.

[Startingover]

Finally got a few minutes to switch everything around 

The new Taccom tension barrel is on the Odin Works upper with the Odin Works forearm cover 

The Rainer Arms stainless 16" barrel and VG6 is on the Jones Arms Kronos upper with the Aero Precision forearm.

 

The new weight is 6lb 4.4oz vs the old weight of 7lbs 5.5oz

(However I discovered that the charging handle may have been touching for the old weigh in, so it might have been even heavier before)

 

Pics to follow

Patrick - Thanks for posting this link. About to order one.  Mark

[Startingover]

Red dot re-sighted in on the new set up, it was fairly close to begin with.

I also put my 3x spitfire on my other upper/old barrel, and it was fairly close from being on my s&w 15-22

 

But I was having trouble with the Elftmann trigger not always resetting.

So I lengthened the stroke a little, and will see if that cures it.

[Startingover]

We set up for tomorrows USPSA match tonight, so I ran the plate rack a dozen times after we were done.

 

It seems to be running pretty well with the new Taccom tension barrel, so I guess I will shoot PCC tomorrow instead of Limited 10

 

This will be my first USPSA match with it (however I have used it some, in our local Tues night league etc.) so I am pretty excited.

 

It's going to be weird not reloading 5 times in a stage 

LOL
