I did some research seems TKO is one of the better fitment options, check the TKO site or contact them if not listed. OD of LDC needs to be 1.2" or under to clear the air tube, could not find any barrel OD specks, would need to take mine apart to get that.

That’s helpful info. I’ll have the chance to measure min directly when my replacement barrel cover arrives.

My Google fu is slow today, check post above for update.

So… according to Mike, the OD of the .22 barrels is 14mm. Does that mean that any ole die threaded to 1/2x20 will work?

FYI - I confirmed with Mike @ FD that having the barrel on your Sentry threaded to accept a screw-on Moderator will void the warranty. I was conversing with Neil Clague about having him make me a slip-on that would've attached similar to the stock moderator. Decided to live with it for now as it was going to be $150 and add another 5 inches in length.

Yeah I kinda figure any mod will void a warranty. No biggie. I’ll either learn to work on it, find parts, or if need be buy another. Which I’m actually considering…

Hey, Wayne - would you happen to know what size and material one should look for to source fill probe o-rings for our Sentrys?

Honestly I've only replaced the fill port o ring in my 705-9.  They're the only o ring on these guns that have given me a problem.  I email Mike M. and here's the size that he recommended on account the originals never did work right from what he said.   He did recommend 90duro however I never found them in 90duro so I opted for the 70duro and haven't had to replace one since.

If you have a Calipers, could you please measure the OD of one of those?

Nevermind - it's 5.84mm

Got my.25 cal sentry 705-9t today. I agree with the statement that it's a lot better looking in person than in a photo. When I first went to load one of the magazines I I was not liking the design much but finally got the method down. Looking at the mags it don't look like the NOE hunter magnums will fit. I fired 2 shots out of it and I have to say, it is pretty quite. I had to stop because it was freaking out one of our dogs who was hyper sensitive to booming noise from the thunder today.

[Madd Hatter]

Well, I'm pretty disappointed. My new sentry either used 1000 psi for 3 shots or it's leaking. I'm pretty sure it's leaking.🤬🤬🤬🤬 I even had the tune.

[Racer1]

That's a darned shame.
At least with the tune it comes with a warranty and Mike is responsive.
 I own multiple Sentries and other rifles from him BTW.

Email Mike if you haven't already.

Was the rifle aired up to 3k or did you check pressure before taking those 3 shots? If previously aired up, to what pressure and how long before you shot it? I would air it back up to 3k and check to see if you can hear air leaking from the muzzle with the bolt closed. Also check the Pressure Gauge where it screws onto the Air Tube to see if it's maybe not tight enough. 

[Madd Hatter]

I aired up the rifle to 3k last night and it was down to 2200 psi this morning. 🤬

[Madd Hatter]

Think I found the leak. The pressure gauge was loose. Even with 2200 psi left in the rifle the gauge could be turned. Tightened it up and filled it to 3k again. Will see what happens. I talked to Mike and he said he opened the ports up to 3.5 mm which as Wayne said is about as far as you can go. He said that he has a 50-50 chance of it not damaging the poppet seat. He also said that most of the time the leak is in the fill end of the pressure tube.

[Norcal]

Hope that fixes you up, Robert! Do you have a selection of pellets to try tk see what it likes best? What power level did Mike set yours to?

[Madd Hatter]

I'm shooting my cast .25 cal hunters. Haven't had a chance to do a shot string with it yet but at 3k psi I'm getting 775 fps but that should  go up as the pressure goes down. I know at 2000 psi I'm getting 750 and the pellets are 29.2 grain.  He opened the ports as far as they could be safely and the power wheel is set on 4.

Glad to hear a little tweak got you squared away.

We'll see in the morning. In the mean time I finally got to do a shot string and while it's not a power house it looks like it will be great for plinking.

Pellet geometry does make a difference.  You might want to change.  Or not.   My .02

I'm like Wayne, I don't buy pellets anymore I just recycle the lead from my bullet stop.

I intend to go that way also.  I like my Sentry .22
