very sweet! I want an nds xm lower so bad...

If you get an aim surplus nickel boron bcg, like i did, it looks just like xm16e1 chrome bcg.

On the way.
Based on your review.

Well my "I spent my life in the rear with the gear" XM16E1 now complete with the iamarangemaster approved AIM bolt. Thanks for inspiring me to complete the build.
I think it looks much better with the "chrome" bolt. What to you think?
If you have ever thought about a retro build I highly recommend it. Difficulty level on parts aquisition is still mid level and assembly is well into the low range. Very rewarding project.

Yep, poor man's XM16E1 chrome bolt!

Well, I went and battle sighted the "BTDT 603" on the 50 yard indoor range today! OMG, I love it! If I closed my eyes, it was 1974 with DI Prater coaching me through battle sighting my M16A1! Sure I love a shorty, but there is nothing more pure retro than a 603 or 604 build.

The JT worked over 1/7 barrel from Boywonder777 is AWESOME! At 25 yards, I had cloverleafs from both 55 grain Federal/Lake City M193 and CBC MK262 MOD1 OTMs with 77 grain Sierra Match Kings. I used an M16A1 sight in target, and had POI 1" below POA at 25 yards. DEAD NUTS ON! I love the AIM Surplus Nickel Boron BCG. With the Type D stock, it passes for chrome and gives me a poor man's XM16E1!

The only bad news is that it has a tight chamber. While it functioned flawlessly on the factory loads I tried, it hated my 55 grain handloads! 1 out of 3 would not chamber, even with a whack from the forward assist.

I can't bear to Californicate it and make if "Featureless" so I can lose the bullet button and 10 rounders. It is as intended, and I have my Mini-14 and featureless mid-length carbine in progress to fill the high capacity need.

I put together a retro years ago with a SP1 upper 1/12 twist. It should have a 3 prong flash hider and I may get one yet.
