txhunter58, I was curious about same, when I get an Omega. Williams makes a receiver peep for about 30-35 bucks and was listed for the first time in Cabelas this year. NOW, I think Thompson/Center make's one but it is not listed. Go to www.gunbroker.com and look under the firearms parts section and then click on 'sights'. Do a search for peep. You should see 2 or 3 listings for T/C peeps with photo's. Look up item 15017764 this is in the old blk/yellow packing, its shows it is for a System 1 where it is marked, just above it, it shows Encore. I believe the Encore and the Omega have the same receiver pattern and would fit. The current peep for the Encore,online T/C accessories is model number 7193 or 7793,,and would warrant a call to T/C to see if it fits.
