80%Arms.com DPMS style build question

[txchl]

8)  New to 308's.  I purchased a 80%Arms.com 308 paper weight and an "80%.308 Easy Jig" recently.  I prep my paper weight and now it is a DPMS 308 Lower.  Well nearly.  I purchased a DPMS 308 lower kit from "Cheaper than Dirt" mainly because it had all parts particular to my lower.  I assembled my lower last night with these parts.  All parts fit and function checks good. 

Now to the problem (sorry for long road to problem). :blahblah:  My safety passes the function check (both of them), BUT when I move it from safe to semi there is not a positive stop at the semi position.  Also, both stops (at safe and semi) are not perfect 90 degrees like on manufactured lowers/safeties.  They are closer to 100 degrees with point of safety pointing past 90 degrees.

I have made a video and taken pictures of this problem for viewing by admin and/or people who know about these things.   Well I made video with my iPhone and site will not let me upload???

Any help or suggestions will be appreciated, even if it is buy another paper weight and try, try, try again.  :o

Thx for your time and help.

The safety has it's detent holes drilled wrong.  Get a different safety lever.

 

Did you have to drill the safety detent hole in the lower?

No I didn't have to drill safety detent hole in lower.

 

Do you have a picture of the safety detent that goes in this build?  Maybe I put the wrong one in hole.  It looked like a miniature level weight like you use to do a weight and balance on an airframe (if you know what that is).....  Sorry it's the Army rotary wing mechanic coming out in me.  :banana:  It looks like a miniature pointed bullet with casing.

who is "sig", would want you to loose your glass eye, that is if you had one.   <thumbsup>

[txchl]

AND.....  what border are you talking about.  Hussein doesn't want borders.....

[shibiwan]

Sounds like you have the right detent pin. Make sure it engages the groove on the "end" of the safety selector and that the detent pin can move freely within the groove and catch the two indentations at the end of the travel of the safety selector.

Thx shibiwan.....(that's my new word for the day)...  I'll disassemble and check it out.  Approximately where at in AZ are you?  I went to high school in Sierra Vista.  Ah the good ole days.

[txchl]

I want to thank both of you for taking time to read this.  Y'all be good.  I'll type more tomorrow after I see what's what....

Hope y'all aren't floating away in floods.

 

Stay safe and keep powder dry.

Lived there from '04~'07, then again from '10~'13.

Yes that is the selector detent I used.  Just like on my M4's... 

To think I'm doing all this to have a non-serialized weapon.  ATF probably be here tomorrow.  I'm off for tonight men.  Good night.

[txchl]

yeah, I was back out there for a conference when I worked for the gov't in '07 I think it was.  It's true you can't go back home.....  I was an Army Brat (of the worst ilk), then I was n the Army (3yrs, 10 days, @@@ hrs, but who's counting), then I worked for the Army as a civilian for 29 years before I tore my back up in Afghanistan, then they wanted me to PCS to Rock Island, IL.  Hell no, so I took a medical (I'm one of those evil gov't employees on disability {six back ops later}).  So now I get to baby sit my 3 yr old grandson every day.  Makes a man feel old, proud and afraid about-of and for him.  Anyway.  I'll do some digging tomorrow and let you men know what I found.

If you remove the detent, spring and selector check the alignment of the hole for the detent with the hole you drilled for the selector. The end of the hole for the detent should be centered in the wall of the hole you drilled for the selector. Also make sure there are no burrs in the end of the detent hole where it intersects with the selector hole, it can prevent the detent from protruding enough to engage with the indentations on the selector. I had those same problems with a paperweight that I did a while back.

didn't have to drill this hole.  I deburred all holes, but I will look again for sure.  You never told me what your problem was caused by, let me know if you have time.  Thx.

[guruofhotrod]

Either the Paperweight had the detent hole drilled slightly out of place or the jig I used had the fire control group holes slightly out of place, I'm gonna guess in my case it was the former of the two - either way when I drilled the 3/8" hole for the selector the existing hole for the detent did not intersect the selector hole on center it was slightly forward of center if I remember correctly resulting in the selector not being "clocked" correctly.

[txchl]

what did you do to fix that problem.  fill detent hole and drill new hole?

[guruofhotrod]

I just left it as it was, I suppose it would be pretty easy to press a small aluminum dowel machined with a step in diameter to match the bore of the detent (it changes diameter where the spring transitions to the detent) into the detent hole perhaps with a little loctite 609 and then re-drill the hole first to the small diameter for the detent followed by the larger diameter to the proper depth to allow for clearance of the larger portion of the detent pin then, you'd have to make sure the hole in the grip for the spring was revised to line up with relocated detent hole. To me it was more trouble than it's worth, I can live with the selector positions being off a tiny bit.

 

 

Edit, Looking again at your pics, I now see the wider than 90 degree swing of the selector and as 98 first suggested, it would be 

a good idea to try another selector since the locations of the indentations determine the angle between the positions. The problem

I encountered simply shifted both positions a slight bit but they were still 90 degrees apart and function just fine.

This is what I was immediatley thinking.  detent hole is not on center

[txchl]

hold the presses men.  I disassembled and found the detent could not fully seat into hole (wen converting paper weight into 308 lower I drilled the safety holes on both sides of the receiver).  I failed to remove small amount of aluminum from around the detent hole.  After cleaning this up, my safety works and feels correct now.

 

I want to thank all you for helping me pull my head out of my rectum........   I'll keep you abreast of my build as I go along.  Be good.

I ran into the same issue, had me stumped for a bit - glad that's all it was!  <thumbsup>

Hi all. New to the forum and thinking about starting a similar build. Any update on yours guru?
