Andro Corp MK18 (Crane specd GP)

[everready73]

From my understanding Andro Corp uses Ballistic Advantage Barrels. Not sure if this particular one is sourced elsewhere. The owner posts on the other forum frequently and if you email i am sure he would tell you where they are coming from. His prices for components and uppers are reasonable, assembled rifles seems a little steep

Yes, I have yet to learn of quality of build and components of Andro Corp. As far as I know, DD and LMT have GTG 10.x uppers, but are too pricey. I wish Colt would crank out cheap short uppers, given the low prices on their complete rifles- and the demand is certainly there.

The stripped DD upper is a deal, but too much for me right now. Also, I prefer a Mod0 rifle.

Ballistic advantage 10.3" Hanson Barrel has a .067 gas port according to https://www.m4carbine.net/archive/in.../t-166566.html. While it is not technically Crane spec, smaller reliable gas port size is always better IMO.

I personally have zero cause for doubt when it comes to Ballistic Advantage.

I have no opinion of or experience with Andro corp.


I also have that exact same barrel (10.3" Hanson profile w/.75 lpgb) showing up this week and can informally check it's gas port with allen wrenches (barbaric, but it's what I got, I don't have pin gauges).


There's also Colt:

Sorry, didn't realize the Colt barrel was OOS.


Here's the BA 10.3" Hanson barrel I linked earlier and have showing up:

There's also a lighter version with .0625 gas block journal:

As of this post, if you spend $175 or more on at BA, you get a free upper receiver.

I have a 10.3 BA Hanson on one of my SBR’s and if I ever decided to do a clone, I wouldn’t hesitate to use that 10.3.

I have 6 or 7 AR’s with BA barrels. From my 10.3 to my DMR (18” SS 308) and every barrel is accurate within context of barrel length and all have had excellent fit and finish. Every barrel from my 14.5 and up are sub MOA. Unless you just want to be as close to replicating the Mk18 as you can, i.e. using LMT’a 10.5, I would say you will not be disappointed with the BA Hanson 10.3

I think you Are going to be really happy with your BA barrel. Not saying I understand barrel whip and harmonics, but by owning and shooting a few Hanson barreled builds - I’m a believer in that he found a way to make them a smoother shooter than other profiles like the M4 (BA’s Modern)

The only other barrel I use is Daniel Defense. When I need a length BA doesn’t manufacture like a 11.5. ILL BUY THE CHF barrels. Other than that I’ve used BA. When I build AR’s for others, I’ve used only BA barrels and I’m more strict on quality for their stuff than I am mine. lol

@Robert:

I have been using BA barrels for years and have been pleased with them as well. Glad to read the vote of confidence in the 10.3" Hanson barrel I have on the way, I am positive I will just as happy with it as I am with my other barrels.

[everready73]

Just a heads up if you are looking at the BA barrels check out Granite Ridge outfitters and Monmouth Reloading. They typically have 25% off and free shipping

Rocking a Ballistic Advantage 10.5" barrel. Wish I could remember what the gas port size was. Have a Noveske KX5 up front and A5-0 buffer. Tried an A5-H1 buffer and would need a little heavier, probably an A5-H2, to cycle more smooth. Not to say it doesn't run; it most certainly does. The only failure I have had was when I swapped lowers with my 11.5" that has an A5-H3 and it suffered an FTE, so I would consider that a mulligan as it was function testing. It just doesn't feel the same as my 11.5" or my 16"...it's probably overgassed, or a product of the KX5 on it.

I need to shoot that gun more. It's fun.

Please do [buried in quote, refering to measuring the gas port of my 10.3" BA Hanson barrel with .75 gas block journal]

Almost forgot about this thread.

Using calipers (not more barbaric allen wrench as psuedo pin gauge), I measure the gas port to be .0675.
