Conaso…  I can't find the specs for the Hand Guard or Barrel Nut in the manual that came with my Tac A1..  The info covering this particular item is really just a supplemental insert and not very detailed.  I reassembled the rifle last night and torqued the bolts in the Nut to about 18-20 in/lbs…  It felt good enough…  I went a bit lighter on the Hand Guard bolts.  I would rather have them a little loose than over tighten them.

Essentially, they mainly hold the Hand Guard on, so I'll just keep a Torx wrench with me in the event they back out, but I don't think they will.

See, I told you to check me…    :-[  Sorry about that…  Yes, 62 inch lbs.

I will check my manual when I get home later this evening, but I'm not sure it contains the specs.  I have seen some data for other T3 models and it looks like they could be 15 inch lbs, which wouldn't be far off.  In any event I'll let you know.

Larkin…  I am originally from the UK, but currently reside in the Memphis area.  I am actually shocked at how many shooters there are in the UK, and by that I mean how many people own firearms.  Bit of a surprise really.

I bought my T3x Tac A1 from a dealer in New Jersey and had it shipped to a local FFL (Federal Firearms Licence) dealer for the transfer…  No, you really can't go into Walmart and walk out with a fully auto 50 BMG, or buy a bazooka on line as some news outlets would have us believe…

In any event, I have contacted Beretta (the US distributor and owner of the Sako and Tikka group), but I'm not expecting much of a response other than send it back for service, which I don't want to do if I can help it.

I am considering a Timney trigger, or other alternative, but I really can't see the advantage as their 2 stage trigger only gives a minimum combined pull weight of 1.5lbs.  And I think the stock Tikka trigger is really good and would do the job with the lighter spring, provided I can get it to work correctly, again.

Conaso…  Sorry, I meant to include a response to your disassembly question.  Yes, you have to remove the hand guard, lock plate, and then the action/receiver screws.  The first time it seemed like a bit of a pain in the arse, but having done it several times it's not that much of an issue.

You'll need a T25 torx bit/wrench for the screws on the guard and barrel nut.  And a 5mm allen for the receiver screws (62 ft lbs).

I think the spring retaining/adjustment screw is 2mm or 2.5mm.

Check my specs on the tools and torque specs before you start on it.

Cheers…

I removed the old spring, last night, and installed the Mountain Tactical.  Prior to doing so, I played with the adjustment screw, with the old spring, and it really did not change the pull weight much, if at all and never got much below 3lbs 6oz.  I installed the Mountain Tactical spring, and experienced a similar result…  the adjustment screw didn't really have much effect on the pull weight.  At it's lightest setting, it is still around 2lbs 6 oz (+/- 2 ozs), but would occasionally register around 1lb 14oz and then as much as 3lbs+…  Very inconsistent.  I was expecting a pull weight of less than 1lb, which is what I am aiming for.

I thoroughly cleaned the trigger, but nothing improved.  I may drop it in the sonic cleaner and see if that helps.  It would appear there is something of an internal issue within the trigger group internals.

I've tried loctite, but unless I can get the pull weight to the desired setting, and obtain consistent results, it's not going to be of much help.

And thank you both for the input.

Cheers…
