Spectre Ballistics Light Practical Carbine - NR Receiver Set

Forgive my ignorance, but could one use the barrel of a S&W MP15 on this rig? I understand the gas block isn’t used but can one block it off?

Yes you can use an M&P15 barrel with this. It will work fine. On our test rifles we have not plugged the gas port since they're covered by the handguard. We are going to make a "gas block" that can be used to block off the gas port for those that want it.

Excellent! Great work and looking forward to the progress reports.

Good evening CGN,

We've been spending the last few weeks working on making the rifle feed and extract smoothly. A few things of note, a quality barrel is really important. Extraction will be difficult if your chamber is corroded or poorly finished. Also, really spicy ammo can cause extraction issues too. Overall the rifle is running very well now and we're essentially done all R&D at this point.[QUOTE]...

I suspect that the extraction issues are related to the lack of primary extraction inherent in the AR design. A smooth chamber obviously helps, while a rough, fouled chamber or hot ammunition aggravates the situation. Barring incorporating a camming provision, good, firm manipulation of the bolt handle is going to be a fact of life.

Watching the video I found myself thinking what this would be like as a lever action set up = it would be really fast...

Camp Cook, I think it'd be easier to just have the handle low enough that you can grasp it with your thumb and index finger and then pull the trigger with your middle finger like you're doing a "mad minute" with a SMLE.

Can you run a "bolt knob" on both sides simultaneously for ambi cycling?

I was thinking a L shaped bolt handle or even a little bit bigger bolt handle might make operation a little easier so you can really yard on it.

Overall, I think it's pretty cool.

We're planning on offering more than one bolt knob option. The knob in the video and pictures is the basic model, we're working on a larger model as well.

I think this is great and plan on getting at least one.


BUT this could be so much better if the bolt was ambi or just left handed.
With a heavy barrel, muzzle brake and bipod, mag dumps would still be pretty quick with a left hand bolt.
I know you guys have a lot into it already but please consider making this a lot better for little extra to be added.

It's ambi. You can put the bolt knob on either side.
