After a few months of swapping parts on and off of my Bushmaster, I finally arrived at a configuration that feels the best to me. It can go from irons only to a Weaver Classic Extreme 1.5-4.5x24 in about 5 seconds (thanks to the Larue SPR-E).

 

Here are the specs:

 

Bushmaster M4A3

GG&G Bolt On Flip Up Front Sight Gas Block

GG&G A2 Spring Actuated BUIS

Larue 30mm SPR-E

Weaver Classic Extreme 1.5-4.5x24 with illuminated reticle w/ Butler Creek caps

Troy Medieval muzzle brake

Ergo Tactical Deluxe grip

MGI D-ring

 

Here are some pics:

Very nice, how does it shoot?

I'll know in 3 weeks.

 

I'm on a crazy training schedule for my cycling team and some upcoming triathlons.

 

I'm hoping to sight it in locally and then hopefully join you hooligans for a shooting session down south.

Let us know when, Fort Dix is calling.

VERY VERY VERY nice richie! Awesome gun!

See Chad $300 is a start.

 

Richie, will you let Chad shoot it at Dix?

Richie...I'll give you $300 CASH for it , right now! Deal?

The stock is pinned. Richie knows his s**t , I can assure you that is a NJ legal firearm.

Of course, if he lets me shoot his GSG. :twisted:

 

And IIRC, I promised you to let you try my P99, TB.

You have a good memory, now I have to dig up something fun fot you to try.

Very nice build Richie! Have you had any previous experience with the Troy brake? Any idea of how loud it is compared to other brakes? I wouldn't want to get poked with that thing

No previous experience. Actually, it's all ADCO Firearms had in stock when they were doing work to my upper, so I took it.

 

I've heard some good things, though.

The guys at Adco are good dudes! They did the muzzle and stock on my AR as well. Altho I sent them the PWS FSC556 that's currently on mine. Let us know how it sounds after you get a few rounds down the pipe
