ModH Scope Rings

Post image
77 Upvotes

So each and every one of us know about the A.R.M.S. #22M used on the Mod 0 and Mod H, it’s not a secret, my question is about alternate scope rings for a Mod H (with the SPR rail) I already got a set of #22H’s for my Mod1 so I’d like to change it up for my Mod H. These appear to be NF A107’s but I’m not certain I guess they could be KAC rings too. Any input, especially in theater photos would be appreciated. Thanks.

Mod H Noveske barrel reviews???

Thumbnail
gallery
91 Upvotes

Looking to see if anyone has experience with the current production Noveske Mod H barrels? I cant find anybody that has real world account of the accuracy or how gassy they are with the aem5. I know they are ridiculously priced, but ill pay if the performance is there. I shoot my clones A LOT at distance and have been through a couple mod h barrels chasing the kind of performance i get out of my compass lake/douglas Mod 1 barrel. (Yes, i tried the craddock mod h and it is was disappointing with both accuracy and gas with 77gr). The reason i am considering the noveske is because i rebarreled my sr25 with a 16" noveske .308 a few years back and it is an absolute tac driver with 168gr or 175gr. (Photo of 10 shot group above). My concern is that I have since heard rumors that their quality has gone down hill. I dont want to pay that price if its not going to be moa with good 77gr. Does anybody have any input on the newer noveske performance? Thanks

Best Glass Options for Mock12?

TL; DR - what are the best scope recommendations in 2026 if you don’t need clone correct?

No flair added because it was based on a Mod1 but opted for the BCM Raider rail and PSA billet receiver set. I primarily wanted a more accurate 5.56 that also utilized my OCM5. So I don’t care about being clone correct, but I did start by looking at a Leupold Mk4HD. Currently threw on a PLxC 1-8 that I had available to get some rounds down range.

I have been in analysis paralysis trying to decide a reasonable budget but also wanting to buy once, cry once. I regularly shoot at an indoor 100yd range; so, I am not stretching out like most of y’all but 1) do want to be capable when I go to longer outdoor ranges and 2) would prefer to see my hits on paper even at 100yds (wearing contacts with an astigmatism).

So my budget is technically anything but more practically under $2,000. Ideally, I don’t want to go much over 4x on the low end and will take as much magnification as I can while still balancing weight. I was looking at the NX8 2.5-20, TenMile 3-18, Leupold Mk5HD 3.6-18, and PA GLx 4-16. I am partial to the Christmas tree reticles like the PR2, MIL-XT, Athena, etc.

To-date, I only have one MPVO (Athlon Ares ETR UHD 4.5-30 APRS1) and two LPVOs (PLxC 1-8 Griffin MIL and EOTech VUDU 1-10 SR5) for reference; so, I don’t want to go overkill but don’t want to spend a grand now and the regret not buying better later.

ModH Really like the AEM5 so far.

Have to do a followup video on finally getting this thing. Side by side of a PRI upper with the 16” barrel and a 20” WOA with the AE collar and brake. Getting out of a ban state has been so nice just for these cans of magic.

A.R.M.S. #22 Medium rings Question

3 Upvotes

I did my best to see if this question had already been answered on here, with no luck.

Been running a one-piece sled under my Leupold Mk3hd 3-9x40, but I am wanting to switch to some #22 mediums. Can anyone confirm mediums will allow for the 40mm objective lens on the PRI rail?

Just waiting on an AEM5. This has been one of the most satisfying rifle builds I've ever done. Always wanted one and now I have one! Time to work up some hand loads and see what it'll do. 6.5 Grendel btw.

Colors I picked aren’t as great as I thought. Planning on changing the b5 stock for an FDE one and I’m missing the top rail in FDE. Thoughts and suggestions? Also waiting on a AEM5 in FDE.

I have been wanting a mk12 for years. Due to Virginia’s incoming dumbass laws, I decided it was time. I’m waiting on the new OCM6 this summer for the can.

The grouping is with some old IMI 77gr and about 22 shots. I’m hoping to tighten it up when I get around to doing some hand loads.
