Nice accents on your Armada.    If you look at Terry's (TerryH?) Armada threads, you will see some "bold" paint schemes. 

lol... that TerryH guy. He ain't right in the head.

Where you been hiding?  Race season?

Hi John! You know. This and that and 50 other things. Sometimes life gets in the way. We sold the racing operation over the winter. Really nothing left to accomplish there. Seemed to be about $150k short of taking the next step. Electric racing is not for the faint of heart or the low of pocketbook. lol... A friend in SC is building an electric drag racing museum and he bought it to display there. Pretty cool deal. How have you been?

Well, I installed the mds hammer (from ART) and ran out of adjustment with Tims short  spring and didn't have a spacer on hand. I installed the 10 lb spring (also from ART)  and hit 69.49 ft lbs and immediately blew my breach o ring because of a rookie mistake. I think theres more in it for sure. That mds hammer is so smooth, holy cow what a difference. It came in at 47.9 grams as apposed to the factory original of 78.2. Ill get an oring and a spacer for the dual wound spring and give it a go when I can. I think its going to be a winning combination. What little I was able to shoot, I can already tell the noise is down and the report is snappier.. quicker if that makes since. Ill have little time in the next two weeks and blowing the oring today was a real bummer. I've had this for sale.. but I may just keep it now.

Looks good Dan.

Surprised you ran out of room with the spring. I thought I sent you a 2" spring.

I know that lighter hammer is smoother (and lighter) but you may want to try something out to tinker with. If you can, port the stock hammer by drilling holes in it like the light weight hammer. Kolbalt bit or masonry bit. Or just use a grinder on the sides of the hammer.
You wouldn't believe how much air pressure is generated by the hammer coming home which slows the hammer down. You can also throw a set screw in the hammer replacing the HT screw and make it flush or slightly counter sunk in the hammer. This will allow more travel on the hammer. More travel more power.

Thanks Tim,.. I thought it was weird too. When I get a chance I'll check again. And thanks so much for the tips on the hammer. I'll give that a go too and see how it plays out in the tuning. I have a press and can make my own jigs. Hopefully I can get back to it in a week or so.

Dan I have another one for you. I am not sure how the armada is set up but this is a good read with pics of the mod with results.

Thanks Tim! That's a great mod, I'll be adding that one for sure. I think I actually have a diamond file in my shop.

Been a while since Ive had a day off, had about 2 hours to shoot before dark this evening.  I have a 10 lb spring with the mds hammer from art installed, and war valve. Fixed a leak at the transfer port, I was blowing air out of the breech area. I polished the hammer area of the tube with 1500 grit and its very slick. I turned the adjuster in 2 turns just to see what I would get with the mds hammer. Its 47.9 grams as compared to the stock 78.2 grams. Benjamin domes, 2900 fill. I shot 16 shots going from 715 to 800 which is where I wanted  to start the domes at. The mds at this setup did not want to open the valve till about 2500 psi. This is my string:800,802,807,812,809,809,815,820,816,824,821,820,825,824.824,818,822,818,815,810,808,805,800,798,800.  25 shots, 2500 psi to 1600....looks like about 36 psi per shot. I think with a bit more hammer spring and back off on the valve spring, I can bring the string on earlier and a bit more power. The mds is really easy to cock at this tune.
 So to see how much power could be made with the mds and the 10 lb spring I turned it in 5 1/2 turns and shot this with 43.2 eunjin @ 2700 psi: 738,738,740,741,740,742,744,744,744,751,748,750745,740,738,738. Too slow for my liking but 50 ish ft lbs none the less.  I just want to see how far I can take the mds hammer. Also need to order some stronger hammer springs and shorten maybe a 12 lb hammer spring or a 17. My next test will be with shortys short spring and weight in the hammer till my other springs come in. I really like the dual wound spring. I also want to turn the probe down. I feel I can get 35 or more shots in the 40ish ft lb range as is.. that seems the be the mds hammers specialty. Not wasting air with quick valve closing and no bounce. I like it, but for a power tune I feel im going to need more weight and a stronger spring. Id like to be able to hit 85 ft lbs for 8 shots and tune down for a 40-50 ft lb shot string. So begins the balancing act.
 You guys that have tuned marauders for power or shot count, I welcome any help, advice, comments!!

Had  a couple of hours this evening, tore the armada down, took out the war valve and radiused the port, polished everywhere air enters or exits and lightened the valve spring. I turned down the probe a bit and backed up the shoulder so that it's out of the flow path ( thanks Tim). Installed the mds hammer and dual wound spring. I'll get some air in my tanks and see what I've got. I'm looking for two things.. a shot count tune around 50 ft lbs and a max hunting tune.

Replying to my own thread to keep it updated as I go.
 Update: 11/11- 2650 psi, 48 grain mds hammer, Tims dual wound spring, 1/16 preload?(longer spring) adjuster is backed all the way out. 38.5 bbt. I mag, 905,906,910,915,914,914,912,912. Holy moly... Out of air and time, more shooting and testing tomorrow (hopefully) Wasting a bit of air still so ill install one of Tims slightly shorter springs tomorrow to get a slight gap at 0 preload.

I'm not sure how to word this- but how does the Armada feel?  Does it feel like an AR?  Are the grips too far forward, back, etc.?  I'm thinking about getting an Armada stock (Receiver- PN: 2264-001) for a project I'm working on.  I've never handled an Armada and was wondering how close the "feel" is, compared to an AR.

[oneshot61]

To me... it is of coarse not as compact, slightly front heavy, though to me the gun does not feel heavy overall. Grip feel is similar, but balance is not. I like the platform, the only draw back for me is having to remove the stock to adjust the hammer spring. However, I am doing a mod to the stock to remedy that;). The metal framing makes it durable in the woods (even though I painted mine) and there's plenty of mods and power to be had. It's one of those guns for me if it gets scratched a bit I'm not going to freak out over it. The green mountain barrel is inherently accurate with a lot of ammo.

IMO, the Armada does not feel like a true AR, feel or balance.   It is hard to quantify how different it is.  All I can say is if I was blindfolded and picked up a Armada I would never guess AR. 

Crosman use to sell a pcp upper for AR, MAR177.  I never held one, but saw a few reports that said it was "close" to feel and balance.  It was expensive and don't think it is still available.

I will say, from a project stand point, the Armada parts are more reasonable to work with, the aluminum foregrip being the most expensive part at around $55.

Hmmm...  Does the LOP between the trigger and grip feel okay?  Are you still running that A2 grip?

I have not problems with it, after all its the marauder trigger group and works great for me from the factory settings. I'm a bit heavy handed so too light and I get into trouble. I have the standard grips still on it and have no problems with the way it feels. That being said, there are a ton of upgrades to be had and can be customized totally to your liking. I took all the goofy plastic things of the fore arm and am installing a couple of rails for light and a 45 degree mount for a red dot aside of the scope. I actually like it more than I thought I would. And at 500 bucks with an agnation discount, I couldn't go wrong. I may tone down the stainless look with carbon fiber wrap because this one is going coyote hunting next week;).

Looking great so far bud. Keep us updated.

May you have a target rich environment and little wind my friend!!   

Many thanks for the info!  I will probably pick up the Armada stock for my 6mm build...
