Thoughts on Brownell's BRN-180 Upper?
Brownell's has an upper receiver designed around the AR-18/108 design. Short stroke piston upper and all the recoil springs are self contained meaning when this is put on a standard AR-15 lower you can use a real folding stock.
The gas system is adjustable but didn't see anything mentioned about detents or if there's continuous adjustment possible. |

I become interested in them periodically, but the downsides always outweigh my curiosity. The piston operation system is interesting. I have that on another rifle. It's a bit cleaner and nice to be able to regulate gas without buying a special gas block.
On the other hand, a very good adjustable gas block can (or could be had prior to the current everything shortage) be had for less than $100. The increase in the reciprocating mass may leave it feeling slightly peppy even when properly adjusted. I don't care for the prospect of taking screws out to remove the handguard for cleaning and maintenance. Screws work by stretching a bit, and I expect a screw to stretch only so many times. It's not inexpensive. When I think of the upper I could build for $900, the BRN-180 looks less enticing. I'd fault no one for buying one, but I can't make the leap.

The price is way too high for me. If the complete rifle was $900-$1,000 and a upper about half, it would be very attractive. It's your money, though, so...
