$418.00, what a bargain, even if it required some tweaking, it’s still a killer deal 😀

We will see if and when mine shows up next week!

Neat little Pistol Caliber rifle not too heavy and looks to be well made!
Took a few pictures of the BC10mm chamber support and side charging handle BCG
First is looking through the ejection port
Second is looking through the bottom at the feed ramp
Third is the side charging handle BCG

Thanks Wade

[The_Shadow]

Today was doing some magazine fit testing on the BC10mm lower. This take the Glock 10mm mags and they are a great fit with a firm lock in place and empty mags drop free when the mag release is pressed. Oh the SMJ 30 round mags look awesome and also fit very well.
I’m sill searching for the optic sights for it.
Trigger seems a bit tough on pull but has loosen up some while working dry-fire. Will do a lube check and cleaning if needed.

Hey Wade, you had a chance to take it out yet?

[JAOwens]

I was looking at one of these myself. Looking forward to a range report.

Pretty cool piece. Quite a bit more affordable than say, a Banshee.

Wasn’t happy with the original stock with the exposed screw and found a guy selling a nice stock for a great price.
See picture of original and the replacement I purchased.

Nice, sounds like an overall better setup

I just picked up the BCA 10.5″ pistol and put an arm brace on it. Ran fine out of the box and so far shoots the Blazer 180gr FMJ and S&B 180gr JHP really well with the S&B the most accurate so far.
I’m going to test the Sig 180gr FMJ and JHP, Fenix 180grFMJ, Hornady 155gr and 180gr XTP, and Under wood 115gr Xtreme Defender, 150gr JHP, 200gr JHP for accuracy. Shooting out to 50yds so far. I put a 3-9×40 scope on it. I shot some Magtech 180gr FMJ but it didn’t seem to like those as well but good enough for hunting.
Next step is to put a Rise Armament 140 trigger in it. I just picked it up from my FFL on 7-12-24.
I had a TNW Aero carbine that shot good but the trigger sucked and didn’t improve much after putting in the enhanced trigger kit.

I took it out shooting today but didn’t get too far. I first tried Fenix ammo and had a case separation in the chamber. No damage other than not be able to fire any more ammo due to the top half of brass stuck in the chamber and I didn’t have a range rod or pull through with me. I had added a increased power spring and a 10oz buffer to it before shooting based on reports I had seen about it launching brass 60-75’away. I didn’t have any problems shooting the Blazer 180gr, Magtech 180gr, or the S&B 180gr JHP ammo yesterday using that spring and buffer set up. I guess it will have to wait till next weekend to try out the other ammo and I’ll be sure to bring a range rod and bristle brush along with the 10mm/.40 pull through cleaner. The case popped right out with the pull through after spraying some Breakfree in the chamber. I did shoot my S&W 317 22lr revolver along with my Glock 43X 9mm while out there today. Yesterday I had my EAA Witness 10mm to shoot with the carbine and a Charter Arms Pathfinder 22LR.

The Fenix ammo has been a lot of fun for me, when they have it in stock that is. I’m pretty sure it’s as hot or hotter than Underwood’s 180gr stuff

[The_Shadow]

Hunter5567 where did you get the 10 oz buffer from? I have considered that option as per the others reporting the use of the stronger buffer.
Please let me know if the Fenix ammo worked better after the next testing.

[hunter5567]

It’s a Kaw Valley Precision 10oz Tungsten buffer and increased power spring. I got them from Optics Planet as they were on sale.
I had seen where someone had gotten a 11oz buffer but I don’t know where they got them from. I’m going to test the other flavors of 10mm ammo before trying any more Fenix ammo. I’ll be sure to bring a range rod and pull through cleaner next time. Might be a bit before I can get out to test with immoderate weather coming in this weekend and possibly all through next week since I shoot outdoors at my hunting club. I think I had read where someone had used an AR10 buffer spring for more power as well but might need to be shortened for the pistol tube. I’m hesitant to fire any more Fenix until I can figure out what happened to cause the case failure as in, did it occur from premature opening of the bolt when fired. This was Fenix range ammo 180gr FMJ with Starline cases. The Underwood ammo could possibly have the same thing happen since it’s close to or equivalent to the Fenix velocities. I wonder if I should tie it down and use a pull string to test first shots. I’ll probably try some Hornady and Sig ammo first along with some of my BE86 180gr XTP reloads. The Fenix worked fine in my locked breech pistols and S&W 610 revolver.

Thanks for the response about the buffer. I did find an 11 oz tungsten buffer but haven’t found a higher spring rate for the application as of yet. Wolff Gun Springs shows an extra power spring, but the weight isn’t shown. I may have to contact them for that info.

[hunter5567]

I tried Sig 180gr FMJ and JHP, Underwood 115gr, 150gr, and 200gr, and Hornady 155gr/180gr XTP ammo and all worked flawlessly in my BCA pistol and shot well out to 25yds. I shot 3 rounds of each off the bench in between rain episodes yesterday(Sunday). Haven’t tried the Fenix again but will later on in testing. Still have some Nosler 180gr ammo to test. My Hornady 180gr XTP/Be86 reloads rain fine but one case did get caught in the ejection port and got mangled. Might have to increase the charge a bit for use in the BCA upper. I am running 8.2gr in those curently. I am using a 3-9×40 scope on it.

Sounds great!
