Can an AR be built lighter than Bushmaster's Carbon 15 rifles? How close can you get with aluminum uppers and lowers? |

Not without going to similar extremes (e.g. turning barrels down real thin, fluting a lightweigh barrel, and/or removing material from the receivers. Forest has a great table on the Maryland AR site. If you use all of the very lightest components, you can get close to 5 pounds empty, but you're not goint to get down to 4 pounds like the lightest Carbon 15. I have a superlight built around a Cav Arms Mk II lower, a Bushy Superlight barrel, a one-piece carbon fiber free float tube and a Les Baer flattop upper without a forward assist. I also used a Colt bolt carrier that's not closed on the end to save a few more ounces. IIRC it's 5 lb 6 oz empty with a OKO 4W red dot and about 5 pounds 3 ounces without the red dot. It's a handly little carbine. |
do you have any idea of how many customers I have had come to me and ask me to fix their cf pistol or rifle because it cracked at the pivot pins or cracked were the Bbl nut screws on. I'm not here to bad mouth anyones product but come on...... |
