Ultralight Ultralight Rifles

[4090Sharps]

Here’s my current UL build I’m working on. I got Deadshot Barrels to chamber one of their lightweight contour 17 cal barrels using my .17-5.56 KAK reamer for a lighter predator calling rifle.

The barrel still weighed 27oz but it’s 20+ oz lighter than my other .17-5.56 barrel. I got tired of lugging that thing around. A suppressor will add another 10-11oz to the current weight.

I had to look up the caliber. Pretty sweet! A 17gr bullet would turn little critters into goo for sure at 5000fps. I’m curious how the barrel life and the semiauto functions with standard ar’s. I just assume you need a lighter spring to get it to function properly.

I’ve only fired it suppressed in a standard AR with an adjustable gas block so far, didn’t bother changing the spring or buffer. The recoil and cycling feels nearly imperceptible in a 9lb gun.

I had an oopsie with my first rifle in the caliber after I loaded some ammo when the powder measure hadn’t fully settled. Ended up way over pressure and blew a case head. Pressure ramps in the 17 cals quickly.
