USFT in da house!!!

[YEMX]

I tore my parts drawer up looking for my thumb rest but couldn’t find it. I swapped grips to a target style 911 grip and the rest wouldn’t fit anymore.

And for the life of me I can’t remember when I removed it if it was just a bolt holding it on or if it did something else with the trigger.

Congratulations on it. I love mine. I like to put just a touch of silicone lube on the breech oring when ii shoot mine. I also keep it swung open when stored.

I appreciate the effort!!  Thank you!

Thank you- I've been lusting for one for many years!  I'll start doing the silicone lube on the breech when I do start shooting it, thanks for the tip!  Yes, cavedweller mentioned the same thing: keep the breech open so the o-ring doesn't take a set...  Which is how I'm currently storing the rifle. 


I'm almost tempted to just unscrew that rear screw and see what happens...  I'm not going to really do it without confirmation, but I'm REALLY tempted to!  LOL  It really does look like it's just a cover plate that those two screws are securing.  So it shouldn't affect anything if I just take the rear one out.  But again, not knowing what-all is in there and how everything secures, I'm not willing to be the guinea pig!  LOL

Congrats on the ft rifle Tom. It looks like a very nice rifle and I'm sure shooting it will be a pleasure.

Just got a text from a buddy with a USFT.

I asked about the thumb rest and if anything was connected to it.

He said “ Nope, nothin will happen...go for it.”

So looks like you are good to go. In fine print I take no responsibility if anything explodes or there is a fire when you remove it. 😂

YES!!!!  LOL  This is good news.  I'm so glad it's not connected to anything!  Thank you for the info!

Thank you good sir!!

So there's a plug where the original fill nipple was.  Is degassing as simple as removing said plug?  Again, just want to make sure.  Also, not sure if there's a specific way to de-gas these rifles.  If there is, please enlighten me!  Thank you again, for everyone's help!!

When I had to degas mine I shot down and when it got low enough pushed on the hammer against the valve.

Y'know, that sounds like more fun!  LOL  I'll do it your way!

[Motorhead]

Smack the hammer with plastic face hammer, hold the pressure against hammer when doing so and gun will PSSSSSSSSS until empty

Thank you for the info gents!!

*sigh*

Does anyone happen to know the thread spec for those two small screws on the pistol grip? The rear one being the one that secures a thumb rest...  It's not 4-40.

If not, does anyone know what to call a thread checker for screws 4-40 and smaller?    Found it, FINALLY.  It's a micro screw thread checker. 

It's always SOMETHING  LOL

My local Ace Hardware has a gun screw bin in the fasteners section. There is a thread gage for about $5.00. Well worth having.

I live in MD.  Stuff like that doesn't exist here, unfortunately.

I did find a small screw thread gauge on Amazon.  It does both Imperial and Metric.  Won't be here until the 1st.  So the thumb rest will have to wait until after the 1st.  I'll probably have to order the screws from McMaster.  I've got a piece of black delrin set aside for the project.  If I can find my knurling tool, I'll make one from aluminium... 

I got the AF .20 barrel modified (I just cut off the breech section) and polished up.  It's right at 21" OAL.  Which is only slightly longer than the .177 barrel currently in the rifle (over 19", less than 20", not including the LDC adapter).  Also, I'm happy to report that Motorhead is 100% correct, the HD packing tape worked a treat!  With a single, non-overlapping wrap, the O.D. is right at 16.01-16.02mm.  Which is what I'm measuring the .177 barrel O.D. at. 

Now all I have to do is wait until everyone is back from RMAC, so I can find out what O.D. DonnyFL's AF adapters are designed for.  I'm also going to order that Ninja Flex reg, with a custom output that's limited to 1800 psi max, to match the rifle's spec.  At least, I hope to.  I'll send Hajimoto an email to see what's up.

Can’t wait to see some groups.

+1.

I finally got an Arca Swiss plate in, and some t-nuts to attach it.  It's set up on my tripod, and is SOLID.  I'm going to get to shooting some groups very soon.  I'm going to wait on the .20 conversion, but it's in the works!  Don't worry!!

Oh man, .20 on hold...😂👍...still looking forward to it in that caliber!

I'm just not getting the surface finish I want, and I want to make sure that the face of the breech end is square.  It LOOKS square, but I want to make sure.  Also, I currently don't have the ability to indicate off the bore and dial in the barrel.   

Plus, I got carried away again, and I'm not sticking to the original plan of "shoot the snot out of it as-is for a while, THEN probably convert to .20" LOL  Sometimes I get really excited about something and go ham.  I took this "set back" as an indicator to take a step back and breathe,  and just enjoy the rifle as-is, like I originally intended.   

[Duckfish]

Good thinking.  You need to establish a base line before you try mods.  Else you won’t know if it’s an improvement.

Ha...you definitely need to SHOOT that bad boy! 🤗🥳 Those are unicorn PCP's!
