Now that is just Plain Nasty!!
How could anyone go in to pick up their prized rapid With That looking down on you!!!



Stuart

[Remchester]

Yes... 80% 10/22 receiver...Take-down model...
I had drill and bore for barrel retention insert.
This is how it looks now...



Things to do during lock-down/isolation....

Stuart

Cant ever see 80% receivers being available/legal in the uk shame really I'd like to have a tinker with something like that. I have a volquartsen superlite serial no/0001 with a lilja that thing can shoot when I do my bit. Wonder if you guys over there could get 80% rapid blocks made? That would be a fun project!

[Ca_Varminter]

Well for us over on this side of the pond.....
Airguns are not Regulated AT this time!!
No licenses, regulation on power level or caliber....nothing....
Anything that is shoots any projectile, not using gunpowder(explosive charge) is not considered a Firearm..

So doing a 80% Rapid Receiver is pointless over here...

Extra photo.. Here my mill doing it's thing on an 80% AR-15 lower receiver..

[Remchester]

I have an ar or 2 my self a cmmg 22rf convertion and a sabre defence 223/556 but with its balls cut off ie no gas parts just straight pull ie I have to manually cock it with a side lever every shot

Hi Stuart, can I ask a question about this if you don't mind please?

On this picture did you fit one of the 2 smaller O rings from the bottom picture to either side of the banjo fitting?
As it looks like you only fitted the one to the bottle stem.
The reason I ask is that on my MFR I fitted the second O ring between the banjo fitting and the regulator and all the air I put into the bottle purges through the regulator vent and Im wondering if this is my issue.
so I took it off and put the old bottle back on.

Thank you for these fantastically detailed threads you have shared in Technical, they have certainly educated me!

[Ca_Varminter]

Yes, the 2 small BS 111 O-ring are placed on either side of the Banjo fitting!
Dr Bob's QF shouldn't cause your reg to leak.....

Is it a newer style MFR reg, with two holes?

If air is coming from the hole closer to the bottle...
This could a problem of the internal Bottle O-ring the MFR uses
Also I believe Dr Bob was finding some MFR reg's leaks here too.
I he figured a way of sealing this hole(for the set screw to secure the push-pin disk)
So you should contact him
I would try packing the hole with a little Teflon(PTFE) tape as packing.
Then reinsert and tighten the setscrew!

But, if the air is leaking from the hole closer to the receiver..
Then the reg core O-rings need to be looked at!!!

hth,
Stuart

Thanks for this Stuart,
Im going to start a separate support thread as I don't want to derail your thread
