FYI:

I got impatient waiting for support RMA; polished chamber my self; removed bolt and did this:

Step 1:

Took wooden dowel 3/8′ thick and cut 1.5″ slit on one end with thin Dremel about 1/4 inch deep and small piece of tape to hold it, the dowel was about 12-13 inches long. Cut wet/dry 400 grit 1.5″ wide and rapped it till it was just smaller than large end of a fired case; so .460 roughly using my digital caliper; put my dewalt drill on end and spun on end till ran it in and out carefully and slow about 3 times

Note Cheap popular dowel; broke dowel in middle as my paper winding was a bit too thick closer to the .470 inch ..fun getting paper out but did very carefully as it was fully out to walls and removing dowel left it lining the bore

Sand paper wouldn’t pull out so I used very long very skinny flat tip screw driver to collapse the paper on two sides slowly as to not scratch chamber till paper was touching in middle and then used cleaning rod very carefully on front to push out paper while holding paper in middle on receiver end and paper popped out ..this may have not been best way to start but I wanted to take any high spots out

Step 2:

Youtube showed person using soft scrub with bore swab; did the same with drill on one piece of aluminum cleaning rod, the bore swab I think was .45 caliber and ran that in and out 6-7 times; they used a swab and really fine steel wool wrapped on swab for next step but I decided to use Flitz instead

Step 3:

New bore swab and ran green Flitz polishing liquid for final 7-8 in and out gently

Step 4:

Cleaned with brake clean and then used CLP

Step 5:

Tested today and it worked like a champ …night and day difference; 3 test factory Hornady rounds look great no more scratches or heavy bolt lift after firing; would have done a bit more Flitz if needed guessing the key is to not over do it and go slow and easy I tried to be very careful on depth so as not to hit shoulder of neck

Saved money not having to ship this back if I ever got and RMA as requested to Beretta USA the importer

I would have preferred to have it RMA’d as the rifle was brand new and $899.00 but hunting season is almost and I already had gunsmith add 1/2×28 threads and small titanium muzzle brake

I’m going to do something like this for the polish section as mine is rough for sure better after cleaning but needs work; recently had to fix my chamber as it was rough and extraction and way over heavy bolt lift after firing

this is link for spare parts with instructions.. small parts kit might be handy: has 5 snap rings; this site has instructions step by step for setting up vice to make disassembly better; will probably do something like this to make disassembly better and easier

I too am hoping for good result for adding one; i have new tikka t3x superlite that had a muzzle diameter too small for 5/8×24 so i had gunsmith thread 1/2×28 then purchased nemo arms titanium ar15 break with 1/2×28 then had him ream to .030 over .264 bullet diameter and then shoulder it for tdc when tight. Hoping to test the combo out next weekend and add review to this site. My reasoning was not for the brake effect but more for reduced muzzle rise to stay on target; only 1.3 oz

[QuickN2]

That was my thought this Nemo Arms was 1.3 oz so Its not noticeable from balance point of view after threading and the gunsmith timed the shoulder to be TDC as the brake has the two holes on top; testing Sat or Sunday to see how it does and to check my polishing of bore issue for crappy extraction of case from chamber

Thanks for reply; have not heard back from Beretta the importer as Tikka USA website has no support information, got my auto response of we will get back to your shortly a few weeks ago. I think I will just fix the bore myself with a little mild polishing and test it again.

Too bad really as it balances so nice and the 6.5 Creedmoor is such a nice shooting caliber. I had a gun smith add titanium nemo arms muzzle brake to test also mostly for reducing muzzle rise

I had Ruger American go wild 6.5 before this and rifle had bit heavier profile barrel; shot great but wanted stainless steal and this has much better balance for me
