You need to take a look at the R10/Scopion breech on the BSA PCP’s, the bolt runs in an Acetal tube/bearing.As long as everything is sized right they are silky smooth to cock.

Basically, you bore the breech for the bolt 4mm oversize, then make up a 2mm wall acetal tube with the slots machined to allow the bolt to action and lock down. if lube…Read more

Now back to the Edgun…

Reread what I advised in the other thread and it was pretty much bang on the money…Yoda went down to a 2.5mm TP restrictor which I feel is to small and here is why…

The breech end of the BSA ULtra barrel is internally opened out to around 5.6mm for .22 and 4.6mm for .177 at a depth of 15mm, this means if installed as is you will get blow by and lose velocity. I have now bored my barrels in 15mm and brass sleeved them to 4.5 and…Read more

What size is the stock transfer port?
What size is the barrel porting (if it has any) or the port that exits the air behind the pellet?

I seriously feel you would do MUCH better with a reg at 90 to…Read more

if the transfer port is removable a new unit could be machined up, not sure on the barrel porting though

Finish the bullpup, pitch it to who ever will listen and work a licensing deal.

For me this has airarms written all over it…would get you some money rolling in 😉

Its maple…i could carve one from Walnut as easy…i know there is a mistake on this first one, the second would be better

2000psi is a lot, hope you are on an FAC for that rifle

move the cocking forward to between the first barrel band and the action on the pup…miles easier to cock while shouldered. Make it biathlon style if you can.

Make 2, i will have the second off you for sure…PM me as im dead serious.e

Seems like if the shoulders of the threads snug up well enough and the rifled part has a sufficient lead in so that the transition between smooth and rifled barrel is nice and smooth 😀

I started looking at Daisy BB rifle barrels, one around 20inches would be nice but not sure where you can buy spares from and which BB gun fits the bill….I did mail Daisy regarding blanks so who knows.

I just bought 2 for my HW100, sent them to an airgunsmith recommended by AWT silencers.

Remember you can spec barrels at 5.5, 5.51 and 5.52, 4.5, 4.51 etc but you may have to wait longer. i just ordered stock blanks choked.
