Bootleg/Hodge 12.5

[1168]

Dunno if anyone will find any use in this, but it was interesting enough that I’d like to share it. Bootleg adjustable BCG settings are from 1-4, with 1 being the unsuppressed setting. Today I shot a Hodge 12.5” suppressor optimized 0.0625” port barrel with a Bootleg adjustable BCG. I launched like 50 rounds of steel cased and various garbage through it suppressed for fouling. Then I did 10 lockback tests with Federal XM193 in each setting. “Works” means locked back successfully with XM193 10/10. Any failure to lockback was a failure. Solid shoulder contact.

Unsuppressed:
Setting 1 A5H4: works
Setting 2 A5H0: nope

Suppressed with 30SDk:
Setting 2 A5H4: nope
Setting 2 A5H3: works

Setting 3 A5H3: nope
Setting 3 A5H2: works

Setting 4 A5H3: nope
Setting 4 A5H2: works

Later, I experimented with various garbo ammo. The barrel has a small enough port that a light buffer (edit: see my next post) is required unsuppressed with weak ammo. Had to bang out a stuck steel case. More to follow.

Edit: I noted a distinct change in ejection patterns. Suppressed on setting 1, during the fouling shots, Tula fell pretty much to 3 o’clock. Brass cased ammo went to 1:30. Unsuppressed, it went to 4 o’clock, same with suppressed with settings 2-4. Extractor spring is Colt with only a couple hundo rounds on it. Action spring is Colt with a little less than a thousand rounds on it. I maintain that ejection patterns don’t mean much, but, there were 3 distinct piles

Yes, I will.

I did something similar a couple years ago, but not testing a suppressor. I was testing a Hodge 14.5" barrel with an LMT EBCG to see what worked and what didn't.

I like this kind of data. Rock on!

This is the kind of info that needs to be commonplace around here once again.

Shot it again today. Aguila .223 55 gr.

Unsuppressed:
Setting 1
A5H4: nope
A5H3: works

Suppressed with 30SDk:
Setting 2
A5H0: nope. Close, but no.

Setting 1
A5H4: works. A little gassy, but it works.

I also tried unsuppressed on setting 1 with an A5H2, holding it off my shoulder, and had unsurprisingly inconsistent results.

Really intent on making that A5 buffer system work for you, eh?

I like reading testing guys have done on their own. Beats listening to some blogger on YouTube.

Here's what I tested. Here are the results I got. Period. Quick and concise. Not blah blah blah in a video waiting for the meat-and-potatoes to finally be spilled out.

The equipment:

The little doodad in the bottom of the third pic is the gas regulating thingy. I wish I knew how to take pics of the insides, but playing with it leads me to believe that it constricts, rather than bleeds off the gas when you turn it to suppressed. Also, in person, it is clear why the 2nd setting is significantly different from settings 1 and 3, but 3 and 4 are basically the same.

Overall, I like it, so far, for the niche I intend to use it in.

Abnak, the A5 is well suited to this sort of thing to reduce variables due to its biasing spring. Hypothetically, the weights should be in the same position on each shot, yielding greater consistency. I did have one stoppage of the type that 17k and I have been talking about.

Failure to close on a full magazine?

Failure to close on a full magazine?

In this case, not quite full. 26 rounds in a vetted mag of known history. Edit: A5H2

Colt spring?
