Mk11 Mod 0

My barrel just came in from Craddock Precision. I had to mock it up before I get it ready to send to D.Wilson for gas block install.

Cloud rein 3 switch adhesive seems to have.. melted?.. while just sitting in the safe. No rounds through the rifle yet so it didn’t get hot from shooting. Anyone seen this before? Coming from under the switch, ran down the wire and getting on the rail

HK G28Z vs MR308

Is there any notable difference between the G28Z and the HK MR308 other than the button to switch from silencer to normal fire mode? Does the silencer button justify the, at least in my country, 2,000 euro price difference?
Thanks in advance for your help.

‘Poor Decisions’ build complete…for now

I mean, I still have to torque everything to spec, time the flash hider, and see if it runs with a non-adjustable gas block haha. Wish me luck!

PSA M110 mags

I have a friend with the M110 "replica" from PSA in 6.5. And I know he has mentioned wanting some 10 round mags. Can anyone give me some recommendations on reliable mags? I know AR10s are much pickier about components than AR 15s and I have never had one so I am unsure. I would like to get him a few for Christmas.

Aero M5 Build questions...

I've got a Aero Precision build 6.5 Creed. I want to get a .308 upper - I have concerns because i read so much noise on this. I'm trying to ideally use the same buffer spring, same BCG. Firstly, is there any other upper that would match my lower aside from Aero precision? Secondly - if going to a 12.5 or 14.5 barrel, can i use the same BCG/Buffer reliably or will there be cycling issues?

Update AR10

Here is an update from several months ago. Had feeding issues due to fixed gas block. Since then I switched over to an adjustable gas block and she is running flawlessly. PSA lower/upper frame with SOLGW match barrel, LaRue MBT, etc.

Suppressed only tuning

I'm putting together a little 12.5 Aero upper/lower with a BA 12.5in carbine length barrel. I've seen alot of guys talk about how violent it is (I get its a 308), I was wondering what tuning would look like? How useful are adjustable blocks? I've been curious to see how a YHM suppressed gas block (smaller gas port size) would work as well.

ARG3

To be fair, I bought these G3 mags by the pound 10+ years ago. Once I figured out the gas setting, she runs like a top with nothing special AAC blacktip. Shoots more accurately than I can.

I just wish the company had better communications.

Off note. Hey Monarch Arms. Please communicate better. I was one of your original purchasers. I see you commented on my last post on Reddit in a timely manner. But you couldn’t bother to when we first bought into this project many years ago now. Why I don’t recommend anyone to buy from you anymore.

Upgrades for Increasing Aero M5 Reliability

I’ve got an Aero M5 with a 16” stainless barrel that I am trying to increase the reliability on. I had a double feed using quality 308 ammo out on a hunt that’s got me in my head a bit.

Options I have heard to make it more reliable: JP SCS Flat wire buffer spring Adjustable gas block Drilling out the gas port

Are these all good options? What am I missing?

I am open to any and all suggestions. Yes I realize that buying an LMT or other top-tier rifle would fix this, but I am hoping to explore some less expensive options rather than going all in on that.

BCG nor cycling / Failure to Eject?

Hey everyone!

Been having this interesting issue with my rifle. After about 20-30 rds the rifle fires, but the bcg only opens maybe a half to full inch or so.

I've tried different gas settings and ammos all with the same result.

The rifle is a 14.5" PSA Gen 2 lower and upper receiver with a BSF barrel and Bolt carrier, and a springco orange spring.

Wondering if anyone has any insight.

Thanks!

Ruger SFAR 20": Which adjustable gas block is needed with the stock hand guard.

There are a jazillion posts about AGRs and the SFAR, but 90% are with a 16" barrel with many using an aftermarket handguard. I could measure it and then hope I get it right, but was hoping not to reinvent the wheel. Can anyone who has firsthand experience hook me up with a model/part number or a hyperlink? Any help is appreciated.

Feedback on PSA 20" Gen 3 PA 10

Hello good folks,

new to AR10, saw a deal that I couldn't pass up. Bought a built 20" AR10 from PSA. It was on a Halloween special, so bit the bullet, so to speak.

Please let me know what you think. The link for the product is here.

Tape recs

Anyone know of a good brand of tape/wrap available in Vietnam tiger stripe camo pattern? Need some for cable management and don't want to use actual tape, would rather have something removable. Thanks

Law Tactical Folder on an AR10?

I'm building a 20" 6.5cm SFAR to be my end all hunting gun. I've found an ammo the gun likes, I've done the gas block, she runs like a top, and I've got the weight down. Was wondering if anyone has thrown a Law Tactical folding stock on their AR10/SFAR? Would making packing the rifle around so much easier.
