S.D.M.R. Build (Site Designated Moderator Rifle)

AR/M4 Custom Build Forum

My name is Randy and I am a moderator at ar15chatterbox.com and a hopelessly addicted Ar junkie. I am a member of several other Ar and Glock forums and I look forward to learning from you guy’s. This is the start of a very special rifle for me. I commissioned Quentin Defense to build a special run of billet lowers for our website and I am very proud to have been a part of it. I hope you enjoy… :slight_smile:

S.D.M.R. Build (Site Designated Moderator Rifle)… :smiley:

The package:

The Lower:

A couple shots of Jason’s genius with the threaded roll pin replacement…

Now how sweet is that?

And lets not forget the tension screw to make everything nice and tight…

The Timney 3lb. skeletonized trigger and RRA ambi-star. Oh and the Pmags drop free…

Not my best pics but here goes…

Looks really nice. The threaded roll pin thingy is intriguing, at least from an installation standpoint. I’d want to know how well it stayed in the hole, considering that there might be a little bit of twisting force placed upon it. Of course, there’s always Loctite…

Stake it! :smiley:

Just kidding - sort of. It is an interesting concept. I’ve never had any real trouble installing a bolt catch on any of the uppers I’ve done. I don’t have a huge sample size, I’ve only done 5, and used a good LPK each time (G&R).

What upper and barrel will you be using? And what type of optic, if any?

:cool:

You can view the pictorial of the process "From a chunk of aluminum to a finished ChatterBox lower at this link…

I really like those lowers…finish and styling is fantastic, and even though its a small detail, the bolt catch screw in pin is AWESOME and quite the nifty touch being that so many folks who assembled their own lowers know how easy it is to mar the surface of the receiver since you have to punch the pin so close to it.

Now you need to do some more for here so that I can get my grubby lil mits on some of that action.

That thing has promise. Can’t wait to see it when finished.

Very handsome setup! I’m liking these billet lowers with built-in enlarged trigger guards.

Great screen name, by the way. :smiley:

Thanks guy’s! I have big plans for the upper and optics as well just as soon as I can get my truck back in order…:confused:

That lower is great!

10

Looks great! As far as the threaded roll pin, KAC has this feature.

11

Really…tom. I should be picking up my new SR-15 complete lower and had no idea about that. One more reason to get a lil more excited:)

12

that bolt release pin is a great idea

13

I would have killed for a threaded bolt catch pin. I almost dinged up my lower when punching that roll pin for the first time. That roll pin was the biggest problem I had when assembling my lower, everything went in smoothly. The finish on the Chatterbox lower is outstanding, definitely would like one for a new build.

What’s the make on the sling attachment point? Thanks

i like it! reminds me of pof lower kind of

17

Progress is being made…:moil:

18

Wow, that looks great…what a great pair between your current awesome lowers and now your own custom done stripped uppers.

I think its really neat what you guys have done so far with the lowers and they turned out beyond great, so I look forward to seeing the lowers mated with the above upper:)

19

This is shaping up to be a beautiful rifle.

I think that might be the first time I’ve ever seen a fixed stock AR built with modern slinging in mind.

Thank you Sir! I’m am super stoked about it for sure…:slight_smile:

Thanks brother! I try to integrate what I can…
