Lewis Machine looks like about 614
BM about 600
RRA around the same... so all about the same price.

Thoughts?
 
I have a chrome lined 16" RRA that I got a couple of years ago. Very pleased with fit, finish, etc. After a couple of thousand rounds downrange, I am still happy with my choice.
 
Lewis Machine and RRA are both in Illinois not 60 miles from them selves

hmm, thats interesting didn't realize that. Does anyone know the typical twist on most RRA and Bushmaster or does it vary too much?

Im sure its probably mostly 1:7...but I can't really find it listed on most of them.
 
I am very satisfied with my LMT upper; also have a Bravo Company USA (BCM) upper. Highly recommend both. If you look in the tech forum on m4carbine.net there is a stickied post with a checklist of features; both generally check all the items applicable to uppers. They are both chrome lined 1:7 twist barrels.

Most of the Bushmaster and RRA uppers seem to be 1:9 twist. I think for the same money, and the same general availability right now, I'd get LMT or BCM any day of the week.
 
I looked at all 3, but decided on the bushmaster, rra doesnt have gas piston rifles either.

1/9.
 
LMT, especially at the same prices. Does this price include a BCG?

You'll get a properly sized chamber, 1/7" twist, chrome lined barrel and chamber (chrome lined chamber is essential for maximum reliability, IMHO), and very high quality.
 
I'd definitely take a Lewis Gun over any AR.

out of those 3 the bushmaster and rra will be the better barrels.

the only lmt ive had direct experience with had a couple of quite serious problems.
 
Yeah the price that I calculated does. The upper w/o is $485.

Go for it. That's pre-election pricing.

actually, it wasnt mine, it belonged to a guy i see at the range all the time.

it had a problem that was causing it to somehow jam a round above the bolt carrier. it did it several times the first time i saw him with it at the range, with the final giving him such problems that he couldnt get it out at all. it had a round stuck above the bcg, and the bolt carrier was stuck halfway back. it was preventing him from being able to pull the charging handle back because there was the round, on top of the bolt, between the gas key and the charging handle lip. he also could not seperate the upper and lower because the bcg was locked up halfway back into the buffer tube, and really wedged in there.

i looked at it but didnt think it was a good idea for me to mess with it, live round crammed in it. it was such a mess it busted the case open and was spilling gunpowder everywhere. he left with it that way.

he ended up taking it back where he bought it and they sent it back to lmt.

the next time i saw him he was walking up with it and said they took care of the problem.

he was a little upset that it took so long to get it back (about 8 weeks) and said no one at the factory could tell him what was wrong, or what was done.

then the first magazine he tried to fire out of it, it did the same thing, only this time, cracked out a piece of the upper the size of my thumb right behind the ejection port.

this time lmt said they could fix it no prob. all he had to do was buy another upper for 300 dollars.

he now thinks all ar's are junk and he doesnt bring it anymore.

i dont bring up the subject to him.

i really felt bad for the guy because it was his first ar15 rifle and he said he bought it because someone he works with
im sure it was an isolated incedent. ive never seen anything like it.
 
Depends how much you have to spend, what features you want.
There are some nice designs from all 3, and all 3 are reliable.
Personally I like the LMT monolithic rail platform with gas piston, but I also like my Bushmaster gas piston upper (I chose it regardless of price over other companies gas piston uppers) which is mostly traditional M-4A3, also like the Bushy 30th anniversary carbine, and I like the look of those RRA models with the raised flat tops.
 
Get whatever is cheapest. There will be no benefit to getting one or the other. I guess it just depends on which name you like the sound of best.
