I don'y know a cheap one to recomend, but DO NOT by the ncstar one like that. It is cheap and looks good, but even the force of a .22 blows this thing apart. I bought it from Marstar and can't believe they would even sell something like that. I am sure they would have given me a full refund no problem if I sent it back (I threw it out in disgust at the range unfortunately), so this is not a slag on Marstar, but no retailer really should sell such garbage.
