Core15

Both Small Arms Review and Weapons of Law Enforcement have done reviews this past month . Having read both I would encourage others to do the same .
 
Both reviews were very positive eg23 . No issues and sub moa groups accomplished by Weapons of Law Enforcement with a base piston Core 15.
 
I own the di version and its a great rifle. The one thing that was a problem is the buffer tube nut came loose otherwise no problems after 700 rounds and only one cleaning.

I have the Coyote Tan MOE version. Rifle is great, has had no issues after about 500 rounds through it. Upgraded the buffer tube, grips, threw a magpul extended bolt release on it. For the money you're getting a top quality rifle.
 
I'M newby with Ar...Why uprading the buffer tube?

some tubes are better then others quality of matireals, finnish ect

i just ordered the piston m4 from wantstalls can' t wait to get have heard good things about core's pistion system.

At the 'smith trying to fix it.

As for the tube, I guess it wasn't staked. That tiny little step tells a whole lot about the rifle.
