BCA bolt-action upper.

I ordered one to see what they are like and I'm pleasantly surprised.

I bought a 16" 5.56 wylde bolt upper. I'm not a fan of semi auto firearm, I prefer to manually prepare a rifle or shotgun to fire the second shot. .I've pretty much gotten rid of all my single trigger SxS's and O/U's for two trigger guns. I like the idea of a bolt-action upper. An an inexpensive options of changing fully sighted uppers from varmints and pred to big game without hitting the range.

This upper is a lot of fun. It has some quirks, it needs a loaded mag to work smoothly, if the bolt can lay in the bottom of the receiver it hangs up. When the loaded mag is pushing up against bolt it runs smoothly. It's a bolt and I run 10rd mags with five rounds in them, I also have to clip the springs down in them or it makes the bolt hard to operate. A couple loops off the spring it runs like a regular bolt. Last, with the buffer spring in it is a little discerning as the bolt hits it about halfway through pulling the bolt back, once you expect it it works well plus it gives kind of a forward assist.

The good part it is more than accurate for hunting. I grabbed some loads I loaded for another AR bulk 62gr SP over some 2230 and after getting it sighted in put 5 shots in a 2" circle at 200 yards with a Sightron S1 1.75-5x32 scope.

Next is an inexpensive stripped lower, no buffer, no bolt lock back, and a good drop in trigger and see what it does.

A pretty inexpensive way to build a nice little rig that can go from 223 to 450 Bushmaster with just a change of uppers and mags.

Hope this is interesting for some.
 
I have been considering one of these as well. I like the idea of it and the cost is far cheaper than unitah. Thanks for the read. On your buffer issue, just remove it. I've read some leave it, some remove.
 
Interesting! Thanks, Erich.

Ahh, was wondering why you needed a buffer on a bolt gun. :unsure: I was wondering why you would need a buffer on a bolt action.

This product will convert a semi-auto AR into a rifle requiring the shooter manually cycle the action to load each successive round. If you remove the gas tube and re-install it backwards so the gas holes do not line up, an increase in muzzle velocity is possible. Your rifle will retain the looks and all of its functions minus the semi-auto feature.

Kali Key - The drop in Bolt Action AR solution

The Kali Key bolt-action charging system lets you keep, transport, and import the rifle you love, with all its features, in “assault weapon” jurisdictions.

It works fine with the buffer in, just needs a little getting used to. With the buffer in your two pins away from having it semi-auto again.

I want to try it without a buffer. My lower is the AR I won at the Egg Shoot and I don't want to make changes to it as I have a 20P and a 223 upper for it. So my next experiment with a gutted cheap lower with a good trigger and keep it as a dedicated manual bolt lower.

"bolt action" ...... here in New York it keeps you out of jail.

Well there is that, never thought of that angle.

However, not knowing all the nuances of the laws, the lower is the registered part, so how would have you have a lower to add a bolt action upper to it?

I watched a video of one in action, you better not be in a hurry for a followup shot.

You'd be far better off to drop a barreled action into a chassis.
 
Stripped or complete lowers are fine to possess, as are uppers. It's when you put the two together, and if the rifle has certain "characteristics" as well as being semi-auto, it becomes an "assault weapon" (NY definition).

The laws are the epitome of stupidity and appeal to those that also fit that definition. There are still many of us here in NY that know better but expect none the less. Unfortunately we are far outnumbered by the many that vote that believe what they are fed and think the prohibitions make a difference.

It does take some getting used to to chamber a live round.

Watching horse racing at Aqueduct, your sure getting the snow up there Don P.

Back on point. The laws are a trap IMO. If you have both (lower and upper) whats to keep them from saying you have "intent" ? No way I would have both if I lived there. Just saying.
 
The one I'm playing with operates just like a short throw bolt action, once you get used to the buffer spring, I'm looking forward to running it without the buffer.

You drop a bolt action in a chassis to mimic the ergonomics of an AR but putting a bolt upper on a AR lower doesn't make sense.

If you use a fully loaded standard AR Mag the bolt is very difficult to operate l, five rounds in a mag with a clipped spring it runs pretty smooth.
 
AWS, beware they do NOT work with all after market triggers. I am not sure what triggers they do work with
 
I don't have a BCA, Although I have looked at them pretty hard and keep talking myself out of one.
To me the appeal would be the cost solely. But I do like the idea of combining a AR Lower to the BCA upper to try differing calibers. Being a "Bolt" action does make it easier with the "running" as one has no need to "tune" the gas system.

The other issue that keeps me at bay or rather from purchasing is the barrel change abilities I've read on here not as simple as a normal AR ? True or not IDK.
I've been eyeing the 7.62x39 10.5" upper to go on one of my SBR lower s as one option. Then I sit here thinking that the .473" bolt face would be more interesting, which would take me towards the .458 socom if selecting a built upper.

wonder if using a SLED in lieu of a magazine would be smoother
 
10" upper in 300 BO is more fun and accurate. Was looking at BCA for a 22 mag upper - coon gun.

I'd be curious what trigger that fits a mil spec lower wouldn't work. The bolt whether it is hand operated or gas operated when operated pushes the striker down until it catches and it is ready to fire when either bolt chambers around.
 
Colt lowers have different pin size, but BCA sells AR15 uppers for mil-spec lowers, so milspec compatible trigger ? The BCA A10's uppers, recommend 1st gen DPMS style lowers.

Do you have to leave the Buffer Spring/weight, in the Buffer Tube to use the BCA Bolt action Upper ?
Just a thought along the lines of making it a Folding Lower Stock, and just using a LAW's or Sylvan Hinge . Just a little more simpler and loose a little more weight getting rid of buffer system.
