Need some help on a solution, 16” barrel with MK18 arca handguard.

[Eric32]

Hey guys I am swapping out a BA barrel for a Krieger on my MK18 SPR.

Problem: 16” barrel (it’s the only length I can get my hands on right now for a really good price) and a 16” handguard don’t exactly mix when I am using a plan B mount and cherry bomb on a converted SDN6

Solution: maybe find a muzzle device that moves the suppressor forward? Or some other type of solution.

I'm not familiar with that cans dimensions so I'm no help.

These are always an option on the handguard.

What do you need about 1/4" of either the barrel longer or handguard shorter?

Hoping someone with actual experience to chime in.

I've got actual experience with this method.

Your only option is cut the handguard or run a longer barrel. I would do the former. I think 16" barrels are the sweet spot of do it all. Find a guy with a local mill, or use the hacksaw and carefully file after. Spray it black or even better rattle can the gun.

Kaw Valley Precision makes barrel extenders, as well as other mfg's. 3/4", 1" and 1-1/4" are common. Don't know how precise they would be for suppressor alignment.

Could be an option but that's stacking a lot of variables together.

or use the hacksaw and carefully file after.

I was half joking when I quoted the hacksaw picture. A regular old miter saw with a wood blade will happily cut a handguard. I've cut a ton of aluminum with mine, you've just gotta have a solid hold of the aluminum so it doesn't catch and make a mess of things.
Used a miter saw and table saw to take 1/2" off this one and add the bevels for brake backblast clearance.

I am gonna look for a Q muzzle or suppressor mount that moves the suppressor clear of the hand guard. Someone has to make one of those

+1 for cutting the handguard.

Go from this:

…to this:

Used a Dremel for the cutoff, but then had the end machined square on an end mill, then Cerakoted.

 

[Eric32]

thanks to all you dremel warriors but i am not gonna cut my 400$ rail system.

I think I found a solution with the Atlas XL

I’ll keep everyone posted later on when I get everything in.

My concern is the SDN6.....

I’d wait for an 18” barrel. If you’re going to have the length anyways, you might as well get the benefit of more velocity and a RLGS. Also, running some weird adapter isn’t exactly stacking the odds in your favor that you’ll experience the accuracy a Krieger can produce. Either way, I hope it works out for you.
