According to the Garand Thumb review video the SIG does have a CHF barrel with Nitride treatment.

Excuse me for unloading but there are very few forums that discuss all military firearms to the depth that the members here do

Not at all, I'm sure we're all happy for the discussion, especially as right now we're in a bit of a 'slow news day' period for general weapons news.

...

The piston is definitely cleaner; my AUG for example you can barely tell has been fired if you pop it open after a few hundred rounds. 

The question is whether greater cleanliness matters, and is it worth the increased weight / cost / reciprocating mass compared to DI?

Using LWRC, as they are one of the few companies to offer identical rifles in DI and Piston:

LWRC IC DI: 6.6lbs / $1300-$1600

LWRC IC-A5 Piston: 7.3lbs / $2400-$2600

That's + 11.2oz (~an ACOG) + $1000 (cost of an ACOG) for piston ability. Vs just cleaning the rifle a bit, which with a Nickel Boron coated BCG is a pretty easy wipedown. 

...

I'd say the biggest advantage of the SIG LT is the sweet folding stock, rather then it being piston.

Overall I think the LT could be a great rifle, but as with all SIG products, I'd want to wait 1-2 years of market Beta testing before snagging one to make sure all the flaws are discovered.

If you wanted to experiment with a budget option of SIG LT type AR18/AR15 hybrid, the Brownells BRN-180 and PSA Jakl look like a lot of fun for ~$1000.

PSA JAKL:

There's also the Taiwanese T91 piston AR uppers that I hear good things about, also quite budget bang and very close to military spec.

Budget ar15 components from Asia tend to be very close if not full military spec. Only the fancier guns actually deviate from that.

A friend a of mine (serves as a sniper) uses Norinco AR15 for IPSC comps also internationally says its the cheapest and most reliable ar15 he ever owned. ( i imagine that is not down to exceptional Norinco quality,but simply Norinco using mil-spec parts that are the cheapest and most plentiful, while higher-end guns start gaming the bolt carrier mass , buffers , springs and gas system lenghts ,  making guns smother and faster to run but also reduce the reliability.

In this case the concern is mostly the barrel, due to a peculiarity with US import law. Lots of times we end up with EU/Asia/etc made parts but US made barrels. 

However in the case of the T91 I was wrong, its not a US barrel but rather a Taiwanese blank finished in the US:

So all in all an excellent way to get a real military grade piston upper for a reasonable price for testing.

I found a MCX lt 16" 5.56 at Sportsman's Warehouse, I've been looking for months.

Harrison Beene.  That's a name I haven't seen for quite a while.  How have you beene, Harrison?  sunglasses

Too busy machining parts to get on the forums but I shut the CNCs down in 2017, built a house near Key West and retired.  The problem now is I am bored and reading about guns makes me spend too much money.

How are things with you?

Also retired and bored, but without enough money to spend on guns or go shooting.

Well if you've been lusting after one for months, you should snag it while you can - then report back to forum so we can live vicariously through you ;-)
