Download an app called image resize has a blue square with arrow inside.

[SSOUNN]

Or you can use Postimage.org.. You can resize it all you want.. I usually leave it at “DO NOT RESIZE MY IMAGE” after choosing the picture you’d like to upload.. Scroll down to “HOTLINK FOR FOURMS” Click the square icon next to it to copy the link, then paste..

Thanks. I've only used it for two range trips, but no complaints so far. Its lightweight and holds pretty steady (but keep in mind I'm shooting 223)

Nice rifle,
The only thing I would point out is that front ring mounted directly onto the handguard picatinny rail.
You want both rings attached to the receiver OR handguard, but not both.

The top rail is one piece that extends from the charging handle to the front of the handguard. This is how mk12's are done and it works.

Upon looking closer at your photo and your description, I now see the rail extension/riser, Yes, being of one piece it works. Clean set up. safe shooting.

Can someone share with me why 1/8 is a better twist rate for an SPR than 1/7? I have read that, in general, it never hurts to have too much twist.

What is the preferred 400 yard grain (ex. 77gr, 75gr, etc...)?

I shoot competitive Military Rifle Metallic Silhouette (200m,300m,385m,500m) which requires knocking the animals off of the rail, and I have found that the 75gn-80gn bullets work best for me in a 1-8 Wylde chamber.
Powders used were CFE 223, Varget, for the 75-77gn. and IMR 4064 for 80gn.
(Your choice of powder may differ, as there are many choices that will work)
Safe shooting.

Short Answer, No.
NONE of my handloads for my competition rifles will fit into a magazine.
WHY you ask?
Our match rules do not allow ANY magazine multi fed rounds, only single feed.
THAT SUCKS, you say.
Not really, Using a Bob Sled magazine and a Bolt assist devise of your favorite brand, you can actually fire at a good pace, But you have a 10 minute window of record fire so speed is not as important as accuracy.
ALSO, since I handload for my competition rifles, I can exploit the O.A.C.L. to what ever my rifle likes the jump to be to the lands for the most accurate for the given round components.
I'm currently in the process of working on my new 6mm WOA 24" competition AR and since it is a wildcat with hard to find data for, working with just two powders and 6 bullets it's interesting to see how each one works in the rifle and it's preferred powder charge and O.A.C.L. to get the best load combination for it.

(EDIT) FYI: I have been receiving a lot of messages about the faux Ops Inc Suppressor. Unfortunately, I know longer have the contact info of the guy who made them (as well as the reproduction prototype flash hider). I found him on the MK12 thread of ar15.com, so for those that really want to try to find him, you can try searching through that massive thread or asking there, but I don't know if he even makes them anymore.

Looks like I'm gonna be selling it soon, so I thought I'd share some pics while I have the chance.

MK12 Mod 0

PRI upper w/ Douglas barrel
Brownells A1 lower, with a gen 1 SOPMOD stock and A1 grip
Geissele SSA-E
Harris Bipod
Faux Ops Inc 12 Model
And my favorite part of this build: a Leupold Mark 4 TS30A2 (with the hash marks, battery tether, and MK262 turret) w/ ARMS #22 rings

I was also able to get my hands on a custom fabricated reproduction of the prototype flash hider that Crane was developing, but never went to production. Kind of a cool novelty piece.
