Inexpensive Arms

Just a brief overview of a cheap and effective method to eliminate play between an upper and lower receiver.

There's many ways to achieve the same result. This is my method

Model: 1169-B6.5MHB18185R(MF)

Length: 18"
Caliber: 6.5 Grendel
Rifling Twist Rate: 1:8 5R
Gas System Length: Mid
Barrel Profile: Heavy, fluted
Feed Ramps: M4
Barrel Material: 4150 CMV
Finish: Melonite (Nitride)

Groups shown were shot from a concrete bench, with front and rear sandbag rests.

Range conditions:
Temperature: 75F
Wind: N/A

Feed ramps were polished before shooting. Barrel was cleaned thoroughly before shooting, and after every 5 round group for the first 20 rounds.

The barrel initially exhibited poor accuracy, but proceeded to tighten up groups as the day progressed. Notably, there was a rough spot about 1" from the muzzle that smoothed out as the rifle was fired.

Build notes:

-Upper receiver was lapped and squared prior to assembly.
-Barrel was free floated.
-Barrel extension was shimmed with .002" stainless steel shim stock to ensure a VERY tight fit into the upper receiver.
-Barrel nut was torqued and loosened 3x before final torque value of 85 ft/lbs was applied.
-Gas block was aligned properly, and taper pinned.
-Muzzle device used a crush washer, but was pre-crushed before installation so that it could be installed only 1/8th of a turn past hand tight.

Lower receiver has a polished, adjusted GI trigger that breaks cleanly at 4 lbs.

Thoughts: This barrel has potential. As it smoothed out, it started actually grouping, and I think it's probably capable of MOA or better accuracy with Hornady Black ELD-Match ammo.

This is a brief video explaining how to shim a barrel extension to eliminate sloppy fitment, and accurize your AR15.

I'm not a gunsmith, machinist, or expert. I'm just a guy with a webcam and too much time on his hands. This video is provided for informational purposes only. I'm not responsible for anybody who follows this advice.

That being said, I've tested shimmed vs. unshimmed barrels and have found that in receivers that have sloppy fits, this can improve accuracy noticeably.

This will not make a bad barrel good. It just eliminates one small variable in the quest for accuracy.

The following is a brief look at the following Bear Creek Arsenal Barrel:

Model: 119-B6.5Cm41618(M)

Length: 16"
Caliber: 6.5 Grendel
Rifling Twist Rate: 1:8
Gas System Length: Carbine
Barrel Profile: M4
Feed Ramps: M4
Barrel Material: 4150 CMV
Finish: Melonite (Nitride)

Groups shown were shot from a concrete bench, with front and rear sandbag rests.

Range conditions:
Temperature: 82F
Wind: N/A

Barrel was cleaned before and after each range session, and completely stripped and cleaned after 2nd range session.

Because this barrel exhibited such poor accuracy, groups were shot at 50 yards instead of 100.

Build notes:

-Upper receiver was lapped and squared prior to assembly.
-Barrel was free floated.
-Barrel extension and upper receiver had a tight interference fit.
-Barrel nut was torqued and loosened 3x before final torque value of 70 ft/lbs was applied.
-Gas block was aligned properly, and taper pinned.
-Muzzle device used a torque washer, but was pre-crushed before installation so that it could be installed only 1/8th of a turn past hand tight.

Lower receiver has a polished, adjusted GI trigger that breaks cleanly at 4 lbs.

A do-it-yourself video on taper pinning a gas block to an AR-15 barrel.

Just an informal test. This rifle is the culmination of the cheapest parts I could gather together of sem-reasonable quality. The entire build cost 223.00+optics.

All groups were fired from a concrete bench at a distance of 100 yards. 5 round groups.

A Statement about what I hope to accomplish with my channel, and the testing standards.

I appreciate any likes and subscriptions to my content.

This is a range report using an 18" BCA Nitride treated 1:7 twist heavy profile barrel. Mid-length gas, chambered in .223 Wylde.

Model # B223WMHB1817(M)

I do not represent BCA or any other company or organization. I am not paid or compensated in any way for this review. I'm just a guy who likes target shooting on the cheap.

Ammo tested was:

1. IMI Razorcore 77 grain 5.56
2. PPU Match 75 Grain .223
3. IMI Razorcore 69 grain 5.56
4. PPU Match 69 grain .223
5. ZQI 62 grain LAP 5.56
6. Independence 62 grain LAP 5.56
7. Wolf Gold 55 grain .223
8. Independence 55 grain 5.56
9. Tula 55 grain .223 (steel case)


Each range trip, a single 5-round group from each ammo type was fired from a distance of 100 yards.

This is not a comprehensive test. I simply wanted to see what I could reasonably expect from a variety of readily available, inexpensive ammunition.

I paid under 58 dollars for this barrel, SHIPPED to my doorstep.
Is it worth it? You decide.

In the future, I'll be testing several other BCA barrels I purchased using the same ammo/lots in the same order of firing.

In the coming weeks I'll be testing:

BCA 16: Pencil profile 5.56 1:7 twist mid length gas nitride barrel.
