Opinions on Core15 piston weapons?

Pretty much as the title describes says, what say ye fellow TGO'rs? I haven't meddled with them and see they make probably one of the cheapest entry level piston gun so far.

 I have a CORE 15 BCG in my rifle and know a few guys down Fla. way that have complete rifles and like them with no complaints

 

I would have to ask though what you plan on doing with it that you would want a piston setup?

 

setting aside the whole DI vs. Piston argument here I would only be concerned about using a company's proprietary system and availability of parts in the future ( read: obtain a few "service kits" if there are any to keep on hand as parts do wear and break)

 

According to CORE15s website ( PDF rifle manual page 7 ) it has 4 settings Open and unless you are suppressing it will live there, then HIGH and LOW for suppressor work and Removal , if I were to go piston I would want one with an adjustable type regulation like a FAL.

 

Looks a lot like an Adams Arms kit but can't be sure from just pictures, they seem to be the closest to a standardized system

I don't want the kit, just a pure piston driven AR. I am fascinated by them and really want one, just wanted someones input whom has had some trigger time on one and if there were any problems I should be aware of.

I owned a 10.5" Stag 8HL for an AR pistol I built for about 6 months.

 

1. Piston systems are neat. Mine would eat anything, and made tons of noise. Recoil is... different feeling.

 

2. Gas block/piston block gets HOT. Know how your bolt gets uncomfortable to touch? Well, that big ol block is easy to grab on accident. Gloves or go home.

 

3. Cleaning - well, no, you don't have to clean out the receiver as much. Still get some nasty in it from extracting the case, but not as bad. You still need to lube it. That said, for the love of Hoppes, clean your piston. I bought the upper used, and it was a real pain to disassemble the piston system because of all the crud that had built up on it.

 

4. Carrier tilt is vilified as the bane of the AR15 piston setup.... It's extra wear, I didn't have any malfunctions. The wear was obviously present though.

 

5. I sold the piston upper. In the end, it was a novelty to me. I wanted a rail and didn't like the options that were "piston compatible" and I didn't want to have to mod the heck out of whatever other rail I chose. There are more piston compatible options now, so that might be a moot point.
