LWRC SL (lightest piston AR)

You can't go wrong with a LWRC. It's the best piston AR that's made. Last year I purchased the M6A2 model in FDE. I can honestly say that it has never malfunctioned even once in any way. It's the best purchase I've made by far. Only downside is that the rifle is very expensive but as they say you get what you pay for. The model you're looking at is interesting. The website says it's a pound lighter than the M6A2. Says the barrel is not quite as thick. Apparently this saves on weight as well as cost.
 
I was really looking at the LWRC SPR, but at a little over 7 then adding a scope would make the rifle jump the scale a bit so the SL is a very nice option.
 
LWRC makes a good gun.

Piston AR's aren't something I care for. Would you install an engine in the front of a VW Beetle, run a driveshaft back to the transaxle, and leave the original motor just hanging there?

Eugene Stoner already designed a piston in the AR, what's lacking is a general knowledge of why it's best left alone. Retrofitting a different piston onto a finished design doesn't guarantee anything will be better - except the company offering them makes a sale.

"It's cleaner." Not really, all self loading actions dump gas past the brass into the action. Best example of that is the HK roller locked bolts, no gas action at all, dirty brass and bolts every time I shot mine. Secondly, the piston gets dirty whereever it is, what's being said is "I don't want to clean it and accept the results." Well, you don't have to scrub and clean the piston in a DI AR, and there are examples still running after 50,000 rounds.

"It's more reliable." Sorry, we're all waiting to see those test results. There is no reason to conclude a piston on the barrel, with extra parts to transfer motion to the bolt will have less failures. Moot point, magazines and ammo are #1 and #2 for causing stoppages.

If you want a piston gun, fine, get it, LWRC doesn't make junk. The rationale that the piston conversion makes it better doesn't fly, LWRC quality control is what you really rely on. You could add an Adams Arms kit to a CMMG Bargain Bin carbine and get the same mechanical result, about $275 extra to move it forward. The reliability of the gun would be the question point, not whether the piston kit made it so.

Pmags and full power ammo make AR's run better. Me, I like getting right to the piston in less than 15 seconds to wipe it off. I learned how to speed change baby diapers by the forth kid, no sense wasting time scraping a bolt tail. :D
