Hi Hide members, I know many of you guys are AR experts. I have researched the superior aspects of a piston AR rifle vs gas AR rifle. I know now Bushmaster makes a piston version of the AR. Does anyone have any experience or knowledge regarding this AR version? Particularly, can I put this Bushmaster piston upper on an existing Bushmaster or Colt lower receiver? Thank you Hide members.
 
Re: Bushmaster gas piston AR

Piston is superior on paper only. They both shoot the same projectile out of the same barrel. They are both gas-operated systems. General Infantry has been using DI guns for over 40 years because they work. Many piston implements in the AR system are not designed or engineered very well at all and have their own nuances to deal with. Bushmaster's system comes to mind. It is made by ARES and the consensus with them is that they tend to break in less than 10k rounds, and then you have an inoperable firearm..which you paid an additional $600-$800 for over a normal DI counterpart.

Granted LWRC and POF make a decent piston setup...but again they were not designed from the ground up and are basically 'rigs' to what was intended to be a DI gun.

If you are so sold on piston flavor-aid get a FAL, AK-47, or a Sig 550.
Take my advice, save your money if you are buying an AR and do it the traditional way. If you don't like cleaning your gun get someone else to do it, or don't fire it. The dirty carrier/receiver card is the weakest argument I have heard to sell a gas piston system. Furthermore, most recreational shooters will never push their rifle hard enough to say a GP system is justified or worthwhile because they'd otherwise be out of commission with a DI gun because there is simply too much accumulated fouling for the rifle to continue to function.

However if you are sold on the Bushmaster piston upper, you can rest assured it will drop in any ar-15 lower and work just fine.

Thanks for your input powder burns. I am not set on the Bushmaster piston system. It was something I read about & had high interest. Thus I started this thread to see if $1100 for the upper is worth the investment.
 
Re: Bushmaster gas piston AR

The bushmaster system is exactly the same as POF. I have a POF upper on a Colt lower and I absolutely love it. It is easy to clean, accurate, and runs incredibly clean. You dont have to lube it at all.

I know what everyone says about the DI system, but after using the DI system for 8 years and switching to a gas piston upper I would never go back.

fixing a non-existant problem, keep your shit WET and you'll be good to go for the life of the bolt. mine has a fondness for Mobil 1 10w-30. i have never had a problem, and ive take it through two carbine courses.yes it will make it easier to clean, but i actually have a passion for cleaning, to me it is part of gun ownership and consider it a ritual. save the extra money and spend in on ammo. :)

Are you serious about using motor oil on your AR? Never heard of it. Works better than regular gun oil?

Yes, It works great. $2 for a quart of motor oil or $5 for 5oz of Gun oil????

Have you herd of "red oil"? USMC type. its motor oil trans fluid and other stuf I cant remember and works great.

Also really like mil comm tw 25b, got some in Iraq worked great on M9, M4, SAW and 240.
 
Re: Bushmaster gas piston AR

just put some milspec on it. makes cleaning them so easy its basically a gas piston. i got a bunch from the company while i was in iraq and Afghanistan. its absorbs into the bold and keeps everything outside of it. so you just pull your bolt of wipe it down and your good to go. its awesome stuff

yes, actually it holds up ALOT better than CLP or remoil. its cheap, and its designed for enignes, which i think get used just a "wee-bit" harder than my precious AR ;-) but to this date i have never had a problem, i use Mobil-1 in all my firearms...and engines :)
