I was working on getting all the parts for my AR PDW pistol build. Well according to all the specs from the manufacturers I should have ended up with a 10" rail and a 10.875" barrel overall. The barrel is a 7.5" and the flash can I ordered from Midwest is supposed to be 3.875" long. I know I'm running really tight be I thought I would have the clearance.
in the end, the barrel to tip of the flash can is 10" and my rail ended up being about 10.125. so an 1/8th inch too long on the rail and almost and inch short on the barrel. I'm getting frustrated being I think I have 2 options. either buy a 8" barrel which still may not be enough clearance OR buy another rail an inch shorter...I just don't know what would be best. need some help from someone who may have gone through something similar.
Thanks guys

If it's 223/556 you could get a 1/2X28 to 1/2X28 thread extension. or the proper size for whatever caliber you have.

That would definitely work! And save you money, time and hassle.

Option 2? Is there a longer break than the midwest flash can? 3" or so?
Did you look at the Noveske KX3 or KX5?

You could set it a little further out on the 1/2-28 muzzle threads with a jam but. It wouldn't matter due to the fact it wouldn't be seen because the handguard would cover it. Unless you have seriously sensative compulsive, obsessive disorder! Then of course you would never sleep at night until you get a different barrel or handguard and correct the issue properly for your expections and perceived outcome. :chuckle: :chuckle:

Check this out. I stumbled across it while checking out some sales e-mails I received. This is the KAK 1/2-28 extended flash can. 5" in length. That should get you where you want to be length wise.

Maybe it's the angle but it looks like your barrel is contacting the hand guard
Its really really close but its not touching.

Now the big question.... How does it shoot 🍻
hopefully here in the next 2 weeks or so ill get out and test it. I have a case of 500rds of .223 coming today specifically for this gun. The gas block is adjustable and Ive never fiddled with one of those so first task is dial that thing in. then run the snot out of it till I cant hold onto the handguard anymore...then do it again lol.
The lower is all aces. Spikes tactical lower and enhanced LPK (of course, I love Spikes), and the brace is an SB tactical PDW. no real worries there.
The upper however is Franken gun. Pretty much all donated or parts lying around. Andersen upper, DPMS Barrel, Midwest flash can, Gunshow rando BCG (im really worried about it), donated MLOK rail and Gas block.
So I will be running pretty much all 500 through this thing to trust it. once Im sure it will work then I got to add my optic, handstop, sling, light, ect. I dont want to spend a bunch on accessories yet without knowing it works first.

I ask because I have never shot one where the flash can or suppressor is completely under the hand guard like that.
Interesting look, I like!

1) makes really cool fireballs.
2) make sure you put the right sping in the buffer tube. That way you dont keep giving it gas and it still wont lock back. Duh!
So range trip was short. Ill get out again this weekend...with correct spring lol.

I want to put some type of optic on my Sig MCX pistol but I can't decide between a red dot type optic or something like a 1-4 scope. I like how the Vortex Spitfire and Burris 332 "look" but I'm also of the belief, function, trumps everything else.

MH, are you going to stay with the open sites on this or do you have plans for some type of optic?

Well I'm really partial to Eotechs but man they hurt to spend the $500 on one. Ive heard really good things about Holosun and Vortex. Holosun makes a holographic sight that has a similar redical to the Eotech, longer battery life (like 50,000 hours), two power sources, "auto awake" so its always on AND its like $300. I think I'm going to give that one a go. Its the HS510C if I remember right.
