The plastic piece your referring to is to fill the gap between the stock and barrel. The same stock is used for the T1X as the T3x , only 2 differences that I’m aware of........ the plastic barrel filler and the plastic butt verses the rubber butt pad
mistem,
Thank you for your reply, I appreciate it! I assume it would look pretty much like a gap on each side of the barrel, IF the plastic piece was not in place then? I intend to check the rifle out again shortly - a bit more closely this time. (If Tikka made a stock to match the barrel profile of the rimfire, T1X, I suppose the cost would have been too much for a new mold?)
Thanks again...!
