I was going to use a superlative arms piston kit and it's a no go.

The alignment pin to the top of the receiver did not align with 2 billet uppers i have one San tan tactical one fortis. Do not know if this piece is only for the mega uppers? Alignment is off by a hundredth of an inch.

Instructions says the use of this pin is not necessary but I would have preferred to use it.

Other than these issues the rail is top notch, just wish i could use a piston system like I originally intended to, which sucks

I cannot help re: Alignment, but for the gas-block, I recommend the SLR Hodge Defense Gas Block which was designed at the same time the rail was, specifically for the rail. The other option is the Daniel Defense Lo Pro, but the SLR is a better fit.

Goohead there may not be a piston kit that will fit a Wedge lock. The Adams Arms XLP(xtra low profile) is the smallest I've seen, but I do not know if it's smaller than the one from Superlative Arms. You may be able to contact Adams Arms for dimensions of the XLP kit.

Unfortunately there is no set standard for the alignment pin. I have found that more often than not fore ends and uppers from different manufacturers don't play well together as far as that pin goes. If you have access to a mill I have cut a slot using the existing hole in the upper. Manufacturers should do that already as a slot works just as well to stop rotation and eliminates the inconsistent location.

old11bravo, are those Mega arms rail covers on your rifle? Where did you get them?

Default nailed it! The "M" on the covers is the M-Lok logo. They are nice soft rubbery, grippy covers though!!

FYI the only 2 scout light mounts that work well are mlok polymer and Kinetic qd.

*arisaka, MI, kac are no-go for fit, and the aluminum magpul only allows about 2 threads worth of engagement due to the interface standing off from the 1913 sections.

Well hell...that was your sig I responded to. Mobilfail.

Really? Roy from Weapon Outfitters has been using our Offset Scout mount on the Mega wedge lock ever since they were released. A few of his images:

I thought Roy held his accessories on with super glue and a small wad of bubble gum.

Either a production run change occurred with the rail (Roy got his rail pretty darn early, and I am unsure if any changes occurred since) or with the Arisaka mount (you would know, and probably have said something before hand), or Roy does not have any qualms about the binding that occurs between the Arisaka and the rail on what SHOULD be NON-interface surfaces.

Yes, it will technically work, no, it does not meet my standard for what an interface should be at this juncture.

Here is a photo that should explain:

The MI and KAC looked similar to the above, more or less. The Magpul Polymer section is a thing of beauty.

So guess who has an Arisaka, KAC, MI, MLOK scounts for sale, all new and "un-used"...

The MP Polymer mount cannot be mounted next to the BUIS, or it will VERY VERY SLIGHTLY POSSIBLY interfere with the screw/bolt, depending on the BUIS. However, I really like how mine is positioned in the below photos, and there is no interference that should not exist. To boot, it's also lighter than any of the other mounts per my hand's guestimation abilities (The difference is +- 1/2 an ounce in favor of the MP, depending on the mount), lol

I suspect the Hodge is different. Too bad they didn't simply put two m-lok slots on the 45 degree angles like the Mega has.

It'd be really easy to add a chamfer on the edge of our mount where it touches the rail to give it clearance.

Dstrbdmedic167 has a mega wedge lock and uses our mount as well. Maybe he can chime in:

**Default.mp3** · 25 October 2016, 07:14

I plan on using the Inline Scout Mount on my Hodge rail; is this not recommended? The rifle will be run suppressed most of the time, so I'm trying to push the light as far as possible, so I originally didn't care about the fact that there's only 1 M-LOK slot; should I be?
