On a 4x fixed scope you won't notice it nearly as much as you would on a 3-9x set on 9power.
FWIW, it is EXTREMELY simple to adjust parallax on most scopes yourself, you for $20-30 the company will do it for you.
If your scope has an external lock right on the objective bell, simply unscrew and remove it.
The very end of most scopes, beyond that silver ring on the bell is the lock ring. A rubber "strap" wrench is helpful on tight lock-rings.
You will notice the objective lense in most scopes is threaded into the objective bell, and can be turned out to bring the parallax in closer, and turned in to bring the parallax out further. DO NOT, however, turn the lense completely out and remove it--you will lose the nitrogen charge of the scope.
Sight in on the distance you want to be parallax free. Turn the objective until everything is set, Replace the lock right and tighten. You're done.
I've dont this on 4-5 scopes. I can bring a 100yd parallax scope to 50-60yds in less than 5 minutes.
