So for the people that have the Stag Model 8. How are you guys liking it? Are you seeing a lot of carrier tilt? Is the H3 Buffer worth looking into for the model 8?
Also ,if you guys got the Plus Package over just the default, let me know if you guys are seeing the same deal with Carrier Tilt if at all.

After 2000 I noticed a little wear from tilt. just ordered Heavy Buffers H3.
Also reduces felt recoil I'm told should be here thurs.

Did you go with the Plus Package?

I have a Stag Model 8 and love it now!!!!!! When I first bought it, no ammo would cycle reliably and would jam constantly, some needle files and TLC took care of this and now it has been a blast to shoot. Over 500 rounds now and not a single issue, except for running out of ammo

I recently bought the Model 8, no plus package. I love it. No issues with carrier tilt, however there is some slight wear from the cam pin. Other threads indicate this is normal and I havent had any misfires/jamming, but I think it's still worth mentioning.

For some reason everyone says that piston has more recoil than DI. I can tell you that the Stag M8 has noticably less recoil than my issued M4.

I have the NY state compliant version (pinned stock, pinned muzzle brake).

Edit: I have about 700 rds fired, never jammed/misfired, mostly federal 5.56

I think its weird that some people say that the piston systems have more recoil.. I shot 2 different Piston systems now. Kinda why I want to buy one. One was the Ruger SR-556 the other was the Sig 516. Both of them i was able to shoot with only one hand... Not sure if there is something different with the stag? Ill have to see i guess.

Quest question on the gun. The gas block for the system. Is there only 2 selections on it On and Off? Was reading some where that it only had a on and off which I thought was weird.

Well I went ahead and ordered the Stag Model 8 + Package. Probably didn't need plus package but I wanted the 1:7 Twist (Personal pref). Also gonna throw a DD or Midwest Drop in quad on it. CTR Stock and a EOTech XPS2 on it. Will get picks up as soon as I get it in. Will keep you all up on how it shoots.

You should be very happy with it. My Stag M8 has run 100% so far. I only use 55gr and 62gr milspec ammo, but it ate all of it up no problems. Makes nice tiny little groups if I concentrate.






I love my M8, I will probably get one in 6.8spc next. I also have Zero carrier tilt. I am running a POF roller cam pin, a Spikes Tactical T2 buffer/spring, and it looks fine in there.

I got the plus package on mine, I even shot the cheap tula and monarch steel case ammo with no issues. I love nine, but just recently found out I may not be able to shoot suppressed. I'm still waiting for a answer from stag about that.

What's your optics set up, that lines up perfectly.

Yes, only on and off. Not sure what else you would need. Other adjustments are usually just for rate of fire adjustment on full auto weapons

Its good to hear back from you all about the rifle. This will be technically my first AR. I did pick up a Sig M400. The only thing that came out of it was disappointment.
I own 2 Sig pistols a Sig226 and its brother the Sig SP2022. I love both of them. So I thought what the hell I have been wanting a AR for a long time now just never found one I
liked. I really liked the M400 Enhanced with the Magpul MOE furniture. I only new a little bit about ARs at the time and it seemed to fit the specifications. I only ended up paying
$800 (With background check, no taxes yay for Oregon).

Went out to shoot the gun and it refused to cycle. It would go bang, eject the round but not feed the next one. At first I thought well maybe just the PMag was
having problems. Though I had never heard of any from any of my friends having problems, GI mags yes but not Pmags. I tried 4 different mags and thought it was the PMC X-tac
that was having problems, tried some M855 Lake city that a friend of mine had and then a guy at the range ran some of his home loads through it (He was to cheap to let me
shoot my own gun with his "Match" grade ammo).

After all that and taking it back into the gun shop, contacting Sig. I sent it in and after waiting around 8 weeks I got tired of waiting. My local dealer said he would reimburse me
and give me some store credit for the hassle. Which leaves me hear. After talking to him a lot and doing some investigation. Stag Arms piston is what I REALLY want. So I cant
wait for it to come in. I have a few weeks though. So I get to window shop for the Disco ball and lace garter belt for it (haha).

I have an EoTech XPS 2-0 with the EoTech 3x magnifier with the flip switch. I love the setup, and you are right, the alignment is perfect. Very fast and easy to use. A little expensive and adds some weight to your rifle. But I feel it is perfect for what I need this rifle for. It also clears the Back Up Sights, so I don't have to take them off, all I have to do to use them is flip the 3x out of the way and flip them up.

Only complaint about the 3x is the Eye relief is kinda tight, you really have to be on it to see everything, but once you get used to it things work out just fine.

OK, I have never heard of this before so hopefully someone can help me understand this. I asked a rep at Stag Arms if there was only on and off for the Model 8. If it is only on and off do they plan on changing it in the future or adding a different piston gas block to allow different settings he responded with this.

"The Model 8 only has an on and off. We don’t have plans to change it since the piston is self adjusting. If you have any further questions please contact us again."

What does he mean by the piston is self adjusting? I mean I can comprehend that it adjust its self but. What does it do to adjust its self? Sorry if its a dumb question but it totally threw me for a loop.

I think what they are saying is that the return spring and piston are able to adapt on the fly to the pressure variances with adding a can. But I don't know how that would work really. Unless they used a general timing that would work with both, but you also can't fire subsonic ammo really with the 1:9 twist rate so I don't know.

The plus packaged model 8 comes with 1:7 twist so it should be able to rock subsonic yeah?

Got to shoot my concealed carry instructors Model 8 today. Thing is fricking awesome, can't wait for mine to come in. Should be here next week. Already picked up EOTech XPS2, BAD Lever, Midwest Quadrail, CPR Magpul stock, Magpul grips. Ready to go hit the range.

With just the EoTech it is co witnessed. You could use the EoTech with the BUS's up if you wanted to. I put them up when the EoTech starts to flash for low battery.

so if you was to put up the front sight it would line up with just the EO? what does it look like if you the mag + EO + front sight?
can you put a pic up, i dont' really care about using the back one as much as the front.
navyman8903  [Team Member]
4/12/2012 3:17:21 PM
Unfortunately I am overseas again, so I can't get you a picture.

But I have never thought to use the front sight with the Mag. I only use the XPS with the BUS's when the low battery flash starts to happen.

Got my Stag 8 upper last summer...paired with RRA lower. Got bunch of add ons including the Diamondback handguard...no plus pkg.

When I got it it went straight to the range and I ran into some FTF issues. Bolt was cycling and ejecting but not loading the next round or cycling so fast the next round only made it half way in the chamber and jammed with the bolt. This happened about every 4-6 rounds. So I took it home, got some advise from the beehive, and lubed the BCG and have not had a single issue since. That was a relief!!

The front MI BUIS had some wear and Stag CS replaced it promply...no cost. Diamondback handguard is solid but was really tight on the barrel untill it came off and on a few times.

900 rounds later there is light carrier tilt and cam pin breakin...normal. Shot various 223 and 556 ammo...also no issues with about 50 rounds of Wolf steel.

All said: robust piston design, good CS/company reputation, lifetime warrany, and excellent value! I am very pleased with the rifle...would definitely consider the 3G.

For some reason everyone says that piston has more recoil than DI. I can tell you that the Stag M8 has noticably less recoil than my issued M4.

I have the NY state compliant version (pinned stock, pinned muzzle brake).

Edit: I have about 700 rds fired, never jammed/misfired, mostly federal 5.56


I'm assuming that your issued M4 does not have a muzzle brake.

Isn't it typically subsonic rounds are heavier in weight?

bobo_asms  [Member]
4/14/2012 5:35:00 PM
I could be wrong though. I thought it was typically the Subsonic rounds are heavier in weight. To cause more drag and not allow it to get up to Sonic speeds, causing the crack. There for a 1:7 twist will allow you to shoot them over a 1:9 twist. Just what I have interpreted from information I have gathered while learning about Suppressors and subsonic rounds.

Velocity and twist rate are factors in determining rotational speed used to stabilize a bullet. The rotational speed needed to stabilize a bullet is constant, so a high velocity will require a slower twist rate and a slower velocity will require a faster twist rate. Sub-sonic has a slow velocity so it requires a fast twist rate.

Example: a certain bullet needs 2,000 revolutions per second to remain stable.
2,000 feet per second X 1 twist per foot = 2,000 revs per second (1/12 twist)
1,000 feet per second X 2 twists per foot = 2,000 revs per second (1/6 twist)

bobo_asms  [Member]

So I just got to take my Model 8 out and shoot it. I put about 400 rounds of PMC Bronze through it, like 60 .223 Wolf 62 Grain. Around 120 Lake City 5.56 55 grain. Through an assortment of mags. This thing runs like a fnckin beast. So smooth. Very accurate with the diamond sights from 25 - 100 yards. Got a bunch of pictures to post up of shooting it, the gun and targets. Ill get them up asap. Just wanted to post up though that the thing is just a dream machine. Everything I was expecting and then about 150% more.

Well since I added it, I have only put 3 30 round mags through the gun in controlled pairs. So kinda rapid fire. It wasn't getting to hot. And I have an AFG II so I was worried at first, but haven't had a problem so far. I haven't been in a fire fight with it yet, but next leave I will put 300 rounds through it back to back and test it out.
