I am thinking of a Bushmaster 16in AR 15 and notice that the Dissipator rifle has a longer distance between the front and rear sights than a 16in E2S Shorty Rifle. Would this be better for longer shots? I am planning on using the gun for less than 100 yards. I am also confused on which models have a removable handle or not ?
A2 models don't have removable handles ?
A3 models do have removable handles? Or is it a option you can get on either model.
Do all Bushmaster models have last round bolt hold-open? When they say it has a non removable handle does that mean that a base can not be added latter to the upper to have a removable handle. I kind of like the Dissipator model but am concerned about the non removable handle because I may some day want to add some optics latter.
Yes, a longer sight radius helps with long range shots. It allows more precision.
Well I don't see any 'long range' shots at less than 100 yards <G>. Either sight radius is fine for this distance, though you will get smaller groups with the longer sight radius.
Any model marketed as a 'Flattop' or Bushmaster uses the moniker A3 (Armalite properly calls them the A4 models).
For Bushmaster (and a few others) that would be correct.
ALL 5.56mm AR-15s have last round bolt hold-open its part of the design.
Only a few of the pistol caliber conversions don't have it.
That is usually the definition of "Non Removable".
Then get a flattop Dissipator model, or select optics that do work with the carryhandle (like the Aimpoints, Trijicon Reflex, or compact ACOGs.)
I'm no pro, but sight radius is HUGE for me.
I looking back, I probably should of got the 16 dis. instead of the 20.
When it comes to bushmaster, A3 means its a flattop. You can get the stock A2 style sights as an option( as a rail mounted device). All bushys have the bolt catch.
Added optics to a handle seems to be an easier and cheaper way to go. When you deal with flattops, its in my opinion, the better way to go, but like I already said, its more expensive and more difficult to setup. Plus if your optic ever fails, you still have your stock sights!
This is all coming from someone that still has his stock A2 sights on his flattop, cause I'm going nuts deciding on what I want to do.
Plus figuring out what you want on your flattop is a hassle all in its own.
Sight radius is important.
A small deivation in sight alignment with a LONG sight radius equates to near miss.
A small deviation in sight alignment with a SHORT sight radius equates to a big miss.
