So ive been searching the internet and all my gun magazines and have only been able to find a few companys that make an AR15 chambered in .308 but the ones im finding are more for like sniping and varmit hunting im looking for a small barreled tatical version around the same size as the standard issue M4. Arma Lite inc makes one close to what im wanting and has a 16 inch barrel if i could find one with maybe a slighly shorter barrel that is what im wanting for around $1,500. Also if i get one will some of the after market stuff for the 5.56 AR15 work on it? like the grips and diffrent stocks if i wanted to customize it? Any help on this subject will be greatly appreciated for this will be my next toy after i mod out my remington 870 that im looking for also. Thank you.
