I was wondering if you can tell me what the diameter is at the gas block? I was going to order a couple of BTE blocks but wanted to make sure I ordered the correct one for that build. I know Greg uses them on seemingly everything, what are your thoughts on them? I haven't used the adjustable blocks before but my 6X45 seems like it could bo toned down some so I figured my 6.8 will be the same way( I haven't shot it yet). On the 450 if I do a houge rifle tube over the micro adjustable block 1. Will it fit 2. Is there a way to make adjustments without taking the for end off or drilling a hole in it? Thanks again Brian |

Gas block diameter will be .750 for a standard profile. There may be a chance for some .936 barrels but I don't know if that will happen yet. The BTE gas blocks are the Bee's knees as far as an adjustable goes. The micro will fit under almost all hand guards so you will be fine in that respect. As for adjusting a BTE gas block. They are a side adjust block. If I were going try and cover it like you mentioned, I would adjust the block before I installed the Hand guard.
P.S. I us BTE gas blocks on everything I build for myself. I won't use a sub standard part on my personal rifles if that means anything.

This is Great News!!! Anyone have a price for #1 & #2 Option Barrels? I am also curious if the Brass will Eject from a Regular AR Upper without any modifications?
This would Really Look Good with the New Black Coating ;-) . I would like to compare this to my 50 Caliber Beuwolf, just to see if I can build another Big Bore Upper that's easier to carry and Still make me Smile every time I shoot it??!!.
This is Going to be Great. :-)

This is Going to be Great. :-) No price yet. Maybe they will but I would want the port opened up if I was building. ....and I am. There will be no options on these as to coatings from what I heard last but I haven't talked with anyone in a week or so. Greg |

Greg Greg you mentioned opening up the port, are you referring to where the dust cover is? How much does it need to be opened up? Is it a dremel project? Is there some kind of guide to do by? Thank you Brian |

Yes the ejection port is routinely opened up on most home built set ups. It is neatly done with a mill but a Dremel would work. Ritch has a genuine one from BUSHY he could measure for you.

You will have to open up the ejection port for the 450. You will need to take .035 to .040 off of the bottom of the ejection port.

You can't get the 450 bushmaster direct from black hole. You have to "call" tactical ammunition. Wait..... they do not take orders over the phone..... needless to say I have been getting the run around today while trying to offer mine. Oh yea and the specifications have changed. You can get whatever length you want, but mid length gas with 20" is a negative. Good thing I purchased my forend and gas tube already.

They will work with you. BHW builds the barrels. TA is not the exclusive source for these. My barrels all come in BHW tubes not TA. They are two distinct companies. Contact Ritch on these as he speaks BUSHY. The gas system on these is something outside my experience. Greg Greg |
