Anyone ever build an AR that shoots 6mm Remington. I have been a fan of the 6mm rem for awhile, and have lots of brass, dies, etc. I have been looking at the .243's but really don't to gear up for another round if I could have one chambered in 6mm. I was looking for a project, and am looking for some input.
 
Re: 6MM Remington on AR Lower

You can currently buy a DPMS in 243...seems to me a 6mm rem is about .200" longer and most likely will not fit unless you are talking single shot.
 
Re: 6MM Remington on AR Lower

I was kind of afraid it would be a little long to cycle well. I bid on a r-25 on gunbroker, but came up a little shy. I like the .243, but I have about a 1000 rounds of 6mm rem that I would have liked to use. I am always amazed at the good info that can be had on this site.

Sleeplesstwo, Just have toygunner build you one from scratch. I think you have a cheaper barrel to play with. If it does not work have him build a 243.
 
Re: 6MM Remington on AR Lower

Sleeplesstwo, I think I know of two 243 8 twist barrels that can be had.
 
Re: 6MM Remington on AR Lower

I think the owner of Baldwin Gun Works has a used one that he would sell,and his shooting buddy has one also.
 
Re: 6MM Remington on AR Lower

I would still like to do the 6mm but I think I am really liking the 6mm turbo an a standard ar lower.
 
Re: 6MM Remington on AR Lower

Sleeplesstwo, I talked to Baldwin Gun Works and he has a complete rig for sale.
 
Re: 6MM Remington on AR Lower

The 6BR is apx 150 fps faster than a turbo 40 and doesn't require fire forming the brass.
 
Re: 6MM Remington on AR Lower

6mmRem any day over a 243, faster and will live longer because of the long neck. Havent built one but wouldnt be a problem.
 
Re: 6MM Remington on AR Lower

Sleeplesstwo, I talked BGW today and he has a lr308 for sale.

.243 wssm on an ar platform</div></div>

More power to start out with. Problem is they are too long to handle a good high BC bullet <span style="color: #3333FF">{edit: in the AR-15 platform}</span>. So, in the long run the smaller cases are getting better results out farther. The best you get with these (.243 WSSM's), to feed out of a magazine, is the 90 gr. HPBT's. That will get you supersonic to 1k though.
