Bushmaster

Originally posted by Retseh

For reference Colt, Bushmaster, and CMMG use 4150 steel in their barrels. Colt additionally uses HPT on their barrels for a quality final product. Stag, DPMS, Olympic, and RRA (along with most others) use 4140 steel, which is lower quality than 4150. Stag gets their barrels from the same place that Colt gets their barrel blanks from, but they are 4140 steel.

Bottom line - Bushmaster is a great choice.

They all offer different barrels made of different materials. 4140 isn't a lower quality than 4150, just has different properties for diiferent purposes.

Alot of mfg's also offer stainless barrels as well.

And yes the bottom line is still that Bushmaster is a good choice.
You could always buy a lower and then build up with the parts that you want from different mfg's.

I hope someone can help me with this one.


Ok, I bought a Bushmaster 30 round magazine. The bottem metal plate is black but the mag is gray. Is this how the Bushmaster 30 rounders are? Also, is this a reliable mag? Would it ever fail to feed the shells or something?

thats strange....I have 30 round mags (grey with a black bottom, and green top)

they work fine.....even in post-ban rifles but you didnt hear that from me (well I guess it dont matter anymore lol)

they are reliable, but dont load a mag with all 30 rounds unless you have a good reason (i.e. the russians or whoever are attacking :lol it wears the springs in the mag out.

So that is how Bushamaster makes their 30 rounders, right? So would 25 be safe number?

So what is the Bushmaster XM-15 ES2 a clone of? It looks more M-4 than AR-15.

There was also the Bushmaster Gwinn Assault Rifle/Bullpup Carbine
(AKA Arm Pistol). Some say it was reliable, Some say it was a load of sh1t.

Your links don't have any relation to the use of 4140 or 4150 in firearms barrels, and yes, it does make a difference, 4140 is most definitely lower quality. 4150 has higher resistance to both wear and corrosion.

Here's what you need to know:

groups.msn.com...

Q: What is the difference between Chrome/Moly and Chrome Lined? How does Stainless fit in?

A: All manufactures use Chrome/Moly steel to make barrels - its a type of steel that has some chrome in it to help with wear and corrosion resistance IT IS NOT the same as 'Chrome Lined'. There are two types of Chrome/Moly that are used to make AR-15 barrels. The most common (an most inexpensive) is 4140, its a decent steel that is used on many firearms. The other (more expensive) type is 4150, its got more chrome in it and is more durable and corrosion resistant; only Colt, Bushmaster, and FN use 4150 steel for their barrels. A 4140 chrome/moly barrel is the least expensive barrel you can purchase - yet they can be quite accurate.

So what is the XM-15 E2S? Is it an AR-15 or M-4 clone? Mine is a post ban, but I took the A2 stock off and put a Bushmaster 6 postion collapsoble stock. So what is it? I hope someone knows.

i have a bushmaster xm15-e2s that has had at leased 5,000 rounds throw it and the only thing i replaced was the fireing pin. once i put a 1,000 rounds of really dirty ammo throw it 500 of those rounds were shot in the rain and i didn't clean it for about 6 months and it shot with no problems. so yeah bushmaster is a pretty good gun.
