I bought a crossbow this past summer to use in the newly legalized portion of our seasons...primarily the after-Christmas muzzleloader hunt. I opted for the Barnett RC 150. It is the shortest and lightest adult crossbow made. I think the listed weight is approximately 5.5 lbs and the overall length and width are considerably shorter than other crossbows on the market.
The downside? Well, since it is shorter overall it has a shorter powerstroke thus resulting in less speed and kinetic energy. We are talking about 245 fps with the crossbow bolts provided.
The upside? It is quieter than almost any other crossbow I have shot and if you throw a set of limbsavers on it then it rivals the noise level of an average compound. Accuracy is also very good as I am able to stack arrows at the local shop's 20 yard indoor range.
The crossbow comes with a quiver, four bolts and a red-dot style sight. Price is normally around $200 at most places.
Hope this helps.
