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......

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

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!

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?

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.
