Hadron Pegasus GBB Hop Unit for the TAC-41

[Fatboy40]

I've been having hop issues / quirks with my TAC-41 P for a while now, I've gone back to my trusty DMR, but I thought f**k it and put in a pre-order for the Hadron Pegasus GBB hop unit (and bought the Sniper Mechanics TAC-41 Dampened Cylinder Head (GBB) + 60 degree Flamingo Bucking).

 

I can't see anyone else here discussing the Pegasus so I though I'd start a thread on it for us all.

 

Also I now need to buy a good 510mm GBB inner barrel to pair with this all, and not one that breaks the bank. What brand etc would people here recommend? (I'm only up to speed on AEG inner barrels, also am I correct in the assumption that too tight a bore really isn't good for GBB / bolt action?).

Hi, good day. Pegasus gbb hop chamber was just released officially on the market yesterday hence no one is talking about it, much. 
Currently, am running both aeg and gbb hop/ barrel system on my TAC41A.  GBB type just seals and shoots better. No plans of changing my current hop up system until Hadron announced and released the Pegasus video. I was sold by the impressive barrel, bucking and hop up air seal. The design was more likely similar to EDGI tac41 gbb hop up prototype 4 years ago. But yes, I placed an order, in 2 weeks time it will be on hand.

 

EDGI is my go to barrel, he can cut the barrel according to my specs. My type 96 and LTm40a3 bolty are both running with edgi 5.98mm inner barrels without any issue.

I've just gone with the SBA one to start with, a fair comparison to the stock AEG one, and if the change to GBB / the Pegasus is great I'll probably get a stainless steel inner barrel when I have the money for it.

And it begins (see the below for numerous images)...

However, I'm a little surprised by the marks / marring inside the hop unit itself as shown below...

 

 

... as if something too wide has been inserted into it, and this is it straight out of the plastic container (I'd only taken it out of the delivery packaging from Longbow BB, no inner barrel or other object has been inserted by me). I'll contact Longbow BB about it before I assemble it.
