Newb question

Hey guys. been into these badass things for a couple months now. was buying my kid a laser and realized....i want a god damn laser too. anyway...im hooked. on to the question. i recently purchased a 3w from lucklaser (believe me ive seen the negative reviews, altho not until after purchase) and im actually pretty satisfied. if it isnt 3 watts its very very close and for 150$....ill take it. BEAR WITH ME...the only problem i have is the beam doesnt focus down to well at a distance and im wondering if there is an additional piece i can get to better dial it in. lenses, magnifier...anything really.
i apologize if this is in violation of your guys etiquette and any help would be greatly appreciated -Perry-
