Lets see if this will post . I cam across this in an article , kinda cool how the gas flows compared to a Brake & no Brake .

Its been two years , maybe he sold the build already . <lmao>

Dropping the BCG one a chambered round I guess could do it . I have done it before when I forgot to pack a Mag for the AR I was using at the range & never had a problem , but most say not to do it for the reasons you say . No idea what Primers I was using , I use older WW ,CCI ,Fed. & Remington primers , the only ones I buy now are CCI's . One of the reasons for a Floating Firing Pin , is its ability to self clear debris from its channel . A spring has the potential to withhold debris with in its coils , not to mention the Firing Pin floating vs it being held in a semi fixed position by a spring . This & how the FCG can get some Debris also is why I recommended to clean the firearm to make sure its not a foreign particle or debris causing the Malfunction . This info about how you were feeding the rifle would have helped in the beginning of this thread , but if thats all it is , its a good thing & you should feel safer with your rifle. I used to Polish the FCG Pins & anything else that had contact with another component ( except the Sear surfaces ) , but found they seem to polish them selfs when round count goes up . It helps to polish any friction to friction components . I used to do it with the 1911 Kits from Springfield Armory , way back when & it helped a little , enough to see it on a Trigger pull gage , not much , but it was all in the feel . I just think , as probably others do here, that the MiSpec AR FCG's suck & it doesn't help enough for the trouble .

You could contact the Manufacturer & see if they will make one for the specific Caliber you want to use it for . Worth a try . <dontknow> There may be a slight extra fee , but it shouldn't be much . At least one would think it would not be much .

if I only could . I didn't ask about the 16" ,since I already have one , I wanted something different . I like how the new Barrel has a gas block of .750" instead of .936" , like my other two. Should be a little lighter Barrel up front .

I just ordered a Criterion 18.5" Nitrated Stainless bbl. , w/ rifle length gas system & .750" gas block . Its about two weeks out from production because of the Nitrating . They have Mid length Gas , in stock . Sorry , I just had to make you'all jealous :banana: <thumbsup> <laughs>

Why the dry fire assembly ? You say the components are made of Plastic ? WTF , I'll be waiting for a review & plenty of photo's also <thumbsup>

Nice job on the Camo ! <thumbsup>

Damn Lumber prices are getting up there now a days . Nice looking bench . I build all my own benches . Mostly from old solid wood doors , the ones with the 2x2's inside & a veneer on the outside , heavy bastards . I now have an old Nurses station that work was tossing ,when I worked there .

My 20" , rifle gas system ,S/S Criterion HB , 1-10 twist , no Flutes , has a habit of making one hole groups ( when I do my part ) , but I don't use Factory ammo.

I have looked at all my spares & they all have the std two groves , one in the middle & one on the end . I don't know where this single grove one came from. I reckon if its used with a Hammer with a "J " spring in it , it will work fine .

Check your FCG for any brass shavings or anything else that could cause a problem . Check the BCG firing pin passage to make sure the firing pin is not hanging up or sticking also. You say you changed the Trigger & its spring, how about the Disconnector Spring ? Is it in correctly & the right one ? When you say you polished the pin holes & their openings , were you talking about the Pin holes in the Hammer & Trigger ? Not the Receiver Pin holes ? Too weak of Trigger spring can also cause problems. I'm going to assume this happened after you changed the Components & spring ? There are literally millions of rounds fired from AR's with out a firing Pin return spring , with out slam fires . It would be nice to have one though , just about every other firearm has them . It is usually something in the FCG that is not doing its job of Sear engagement or being prevented from doing so . You could still of had a high primer also & missed it , it happens . Give everything a good cleaning & inspection & re-test the FCG before taking it to the Range after cleaning .

RIP Brother , we will miss you . Sad we never got to hook up to shoot together like we planed .

You say you got the Trigger pull down to 5#'s , what did you do to it ? The MilSpec Triggers & Hammers will not take much of any altering & the Sear engagement surfaces. They are known to have problems when altered , even a little . Surface Hardness is very shallow & suspect . Is this the first problem with this rifle ? What is the round count ? You could have a Disconnector problem also , for the same reason . They will double fire or slam fire or go full auto with no stopping until the mag. is empty . If you want a good , inexpensive FCG , ALG , ACT trigger ( FCG ) is a very good one , can be had for about $ 60-70, Mine have leveled out at around 5# & since they are made by a company owned by the wife of Geissele Triggers , he knows triggers & one of the best around . If you don't mind spending around $100, there is a group buy in the Coupons section at the very bottom of the Thread list for a MechArmor Modular FCG , single stage & a heck of a buy , I have two & they have a clean break & have one of the fastest resets I have seen in a Trigger system . This is a Very Dangerous condition & should be taken care of immediately , of course I didn't have to tell you that. <thumbsup> I have a Rem. 870 mag. that is my designated slug gun for Deer hunting ,I sent out to have the trigger pak to be gone over , to a very well known Trigger smith & it was great for about four seasons & we had just finished a Deer drive & we were standing around waiting for everyone to get bak & I had the DSG on a single point sling off to my side , just hanging there & it went off into the dirt . I emptied all ammo from it & checked it out , that thing would drop the hammer if you just blew on it . I pullded the trigger pak out & the Hammer Sear had sheared off in the middle . Lesson learned , the Factory Trigger groups are not made to be altered , any more , no matter who makes it . I put a Timmney Trigger fix in a new Factory Trigger Pak & she has been working just wonderful , not as great of a Trigger pull as the Trigger job , but I feel much safer . Always keep the muzzle in a safe direction , but you knew that . DPMS 308AR's are notorious for tight Chambers , if you haven't had problems in the past with Chambering , the FL sizings die should be fine . I would cheek the Head Space , just fore the heck of it & make sure the Chamber is clean , scrub it with a brush .

Odd that by just changing out the Buffer & its Spring would change the way the magazine feeds , maybe the BCG is not cycling back as far as the one it replaced . You would think that ,that would cause failure to feed . Replace the original Buffer & spring & test that Magazine to see if it malfunctions with that set up now . They can wear out prematurely , depending on who the manufacturer is . Is the spent case one of the double feeds & not two live rounds ?

Auto correct from the PC police . :yup: That's too funny , its where they came up with the saying " Eat $hit & Die " ! <laughs>

No problemo <thumbsup> , I did a lot of thinking on her using one , she has a small one for when we ride , but it just doesn't work out for her carrie piece .

A very good deal on the threesome , I have to pass , I'm buying a Barrel . I do have another Trigger on the way , so I figured I would build another 308AR around it . <thumbsup> Two weeks ago I had to put new tires on my truck , one developed a large bump in it & man, you want to talk about vibration , damn , it was scary to drive to the tire place . $ 1 K for a new set , I could have built another rifle for that , WTF <laughs>

That's us , but no golf cart <laughs>

Yes they are , sometimes people look every where else, but the Brass catcher .

Its for my wife for when she rides her bike & did you ever think it would be good for others to guess if she is, possibly armed . What about open carrie , does that give it away ? If I wear an NRA or Glock hat , do you think I'm armed & what difference does the color make . <dontknow> I suppose you guys don't wear anything that can possibly connect you to firearms , no hats or 308AR "T" shirts, bumper stickers on you car or truck . <laughs> Think of it as a fancy Purse <thumbsup>

I have a bunch of Brownel's AR 15 mags & have no issues with them & Trippledeuce is correct , they don't put out or endorse bad products . I have been dealing with them for almost forty years .

Got the Fanny pak Holster today & it is not only well made , but I can't even find a loose thread or a stitch out of line. Very well done , I can see more from this company in the future for me .

Well said !

For those who have this Fire Control Group , I recently swapped out my G2S from my 16" 308AR to my 24" Ar 15 & upon disassembly I noticed some thing that could have caused problems with the G2S & how the Hammer pin is secured in the Receiver . I should have noticed this from the installing it in the first place , but over looked it . Check the Photo's below , the G2S Hammer pin is held in place with in the Hammer with a clip that comes with it , since it doesn't have the J-spring imbedded in the Hammers Pin Hole . This is the clip that is used to secure the pin with in the Receiver , it fits in a recess on the Hammer . I used the same pins that were in the std Hammer to the new G2S with the clip installed on the Hammer , not really looking at the pin . I guess I was excited about a good trigger going in my 16" 308AR <dontknow> If you look closely at the one pin , which was in the Hammer , it has only one grove in it & is good if the hammer has the J spring in it , but the normal two grove , should be used with the out side grove going toward the keeper clip on the right side of the Hammer . To secure it correctly , like the spring tail of the Hammer Spring does for the Trigger Pin .
