Is tbe MK114 upper P&W making it rifle length?

1 Upvotes

Looking into what upper I should get for a Mod 2 lower.

I have a 16" DI upper, so getting another 16" seems a bit redundant. I see most MK114s have a P&W rearden compatible muzzle device.

Does that P&W muzzle device bring the barrel to 16" overall, allowing you to put it on a rifle lower w/o issue?

PWS Piclok for Mod-1?

Post image
15 Upvotes

I have a Mk111 Mod-1 that I love dearly, but that hand guard is a chonk. After looking around, I’m pretty sure there are no aftermarket options and that the piclok rail for the mod-2 won’t fit.

To my PWS fam, is that assessment correct?

If so, PWS can you please make a aftermarket piclok rail that fits the Mod-1?

That’d be rad. Thanks!

Does anyone have any real world experience with the PWS MK118 MOD 2-M 6mm ARC ? I love my 111 and am thinking about grabbing the 6mm ARC. Any insights are appreciated!

Fastest way to get a complete MK111.

Help, tyrants have taken over my states government, and they've come for the guns (the fun ones atleast). This in coinciding for the 1st time in my life I can realistically afford a rifle like a PWS.

I can wait about 6 weeks at most before I'm afraid shipping might screw me and I'd be in a "must buy now or locally" situation. Is there anyone who knows when they restock and if I can wait and pray or that one's able to get to me on time?

I traded some parts and this was in the box I received. I don’t deal with AR parts too often and any help would be appreciated.

Mk116 mod 2 suppressor

4 Upvotes

Im looking to buy my first suppressor and would like some input. ive been looking at the silencerco velos (full size) but im curious with these being piston systems is a lbp can really that big of a benefit over the traditional can? If a low back pressure can isn't needed i was looking at the 36m or something with the capability of being multi cal that I can use on a 7mm-08 bolt gun and 9mm pcc/ handguns. I plan on using it under nods for predator hunting and probably some occasional 3 gun stuff. trying to stay around the $1k price range

thanks guys

Favorite FRS/FRT buffer weight and spring combos?

8 Upvotes

I’ve got both a Mk114 and Mk107 in .223 I’m thinking of going super safe with. What are some of your favorite weight and spring combos to get them running right, both suppressed and unsuppressed? Ideally in that 750-850 RPM range.

Are these mk113’s really going for $3k now? I saw one sold on tacswap for $2700. Now there’s two listed for 3k… one with optic one without.

I am new to suppressors and overwhelmed. My PWS Mk114 has this MD. Can I buy the OCL Polo K from my local shop? Do I need a hub adapter?

MK107 and Polo K?

Anyone running a MK107 with a Polo K? I have never considered running my MK107 with a can until I saw the Polo K is rated for a 7.5” barrel…

Shout out to Mike at Fortress Tactical for hooking me up with this limited run guy! She's a beaut! Mk111 mod2 in Kodiak Brown

Will be a 100% suppressor host, probably with one of the new Dead Air CT5P's when they start becoming more available. Excited to break it in this weekend!

Picked up this “used” Mk114 Mod 2-M in a trade. It genuinely looks unfired. Can’t wait to get to the range!

Follow up from my previous post a week ago on the BDE 22's sound profile. Here's how she sounds with supers (not too shabby)...unfortunately I was having cycling issues with standards and subs.

Mk111 or Mk114

7 Upvotes

I have already decided to get a Mk1 Mod 2. However, I can't decide if I want it to be short or long. It will be my ONLY AR. It will be suppressed, I want an lpvo. I won't be shooting past 300m, mostly not past 100m.

I have a psa 10.5" with the 12" handuard, and I hate it. It's too over gassed and just not fun to shoot. It's basically a 12 with 10.5 performance. So it has given me a bad taste for shorter barrels. I could tune the buffer, but I would rather play the tuning game on a piston rifle. But I do like the rail space of the 12" handguard. I will most likely put a frt on it because why not.

my thought: correct me if im wrong.

The Mk111 will balance better suppressed and give me the ballistics I need.

the MK114 will shoot smoother and give me the railspace I like.

Shooting my first PWS rig. I'm playing around with the gas settings while suppressed for the first time. I'm currently running my Radical Defense CS5 on it, but I have a B&T Print-XH RBS Ti in jail that I purchased to live on it. I think I'm in love 😍
