A&D M-11 Drum Adapter

[shawnr1]

fishtix, Problem B is most likely due to the angle (shooting downward) 324 of your M11/mag adapter. I never had this issue while shooting, but I did experience it when I didn't follow the loading instructions. The rim of the rounds were positioned the same as you stated in Problem B.

Don't know if you have tried CCI minimags yet. I think they work the best with the adapter. Also, I get the best results with the 165rd drum.

You have to be careful loading the stick mags as well. The case rims will also overlap and cause a FTF.

+1 on the CCI MM RN. The drums load the rounds in the mags better than I do.

 

[fishtix]

Thanks guys. I'm pretty sure I'm loading the tower right, its essentially vertical and I put a little friction on the drum as the rounds come up the mag / tower.

I just checked my range bag... I was shooting MM HP. I guess I overlooked that in the manual, or I was to exited to get out and spray. Hmm.... Looks like MM RN is up.

Thanks again!

fishtix, I also had problem A until I sanded and polished the circular follower per BBs tech assistance page.
also try increasing the winder to six turns if you have not already.
this got mine working mutch better.

Just got my drums, waiting on Bazooka bros.

 

[m111]

has anyone ran cci ar tactical in there drum adapter? Mini mags are getting hard to find.

 

[harrissr]

get your minimags from natchez . it is the best and the cheapest . i tried the tactical in my unit last week with no probllem but have not done any extensive long term testing. some of the guns run with fed bulk back and some gr with rem gold and some with others. but until i se long term results with the tactical the only thing that i cn say is try some in your gun and if it works , great , but if it doesn't go back to minimag solids / the proven recommendation.

 

[fishtix]

Perhaps I am missing something, but if the only issues why the 275rd and the 220rd(?) drums will not feed reliably is because of insufficient upward force by the springs, perhaps stronger springs would make them feed consistently?

 

[Shattered]

You're missing something... the word is reliable. The larger drums will work. The trick question here is, will they work reliably... and the answer is.... (wait for it)..... no.

 

[fishtix]

Does anyone think that the reliability of the larger drums could be improved by stiffer springs?

 

[Shattered]

No... if that worked all you would have to do is wind it up an additional few clicks with the winder. 165 rounds of ammo is a lot of ammo to be pushing essentially uphill. 220 and 275 rounders are even heavier... duh. We seem to be able to get a happy medium with the 165s. Buy more drums... that's all.

 

[medphys]

Has anyone noticed an increase in reliability when shooting suppressed? That seems to be the case with many M11/22 kits.

Also- I have an idea for a magazine mod that could (maybe...?) increase the reliability with the larger drums... any drum owners are welcome to PM me for details.


EDIT: Never mind on the tower mod. After taking a closer look at them, I don't think my idea is doable.

 

[3S1K]

How much are you guys paying for this setup? I priced it out to about $450. That's with the Tacticl Inc 275 drum with steel. See plate. bazooka drum adapter and e&l in geared winder.

the problem with the 220 and the 275 rnd drums is nothing more than a multiplication of the inherent factors of the 165 rnd drum. there are many who run the higher capacity drum with no problems but in our years of extensive testing we have proven time and time again that the 165 rnd drums are more reliable in the a and d drum adapters. in an am180 position the size of the drum is not as critical but in the upside down position that we have to use the drum there are additional factors. we tell everyone in the instructions that the 165 rnd drums are the most reliable and that is what we recommend but everyone has to find out for themselves. we tell them to use minimag solids and they start with other ammo. your gun may run reliably with other ammo but at least start with the minimags and then try the rem golden or some other brand if you like . these adapters work well with stingers, yellow jackets etc but minimags are consistantly the best non super expensive ammo. we have proven it in over 600,000 rnds of r and d . there are so many forces going on when these drums and gun are running and they are multiplied with the larger drums . this is not a fault of the drums but simple physics. as strobro stated the drum has to be held at a 45 deg angle with the tower and feed slot at the lowest part while it is being charged. val at e and l will tell you to run the cartridges up and down and back into the drum and then release the pressure on the cartridges. i do not do this nor do i recommend this and yes i have tried it but it is absolutely not necessary and is asking for problems. also i do not recommend going above the 5 1/2 turns for the 165 rnd drum in fact many times the m11 needs to have the winds decreased 1/2 to 1 full turn. the new recoil springs from mr lage help in some guns as well. since there is no knob creek this spring i am working on a special buy for uzi talk members on all of our units !

 

[shawnr1]

the new recoil springs from mr lage help in some guns as well.

This is the first I've heard of new recoil springs. Need more info. I will also contact Lage about it.

 

[harrissr]

have a reliable customer that just got the new speing for his gun ; said it helped his functioin with ammo other than minimags which it would only run reliably prior to the new speing.

Is anybody interested in doing a video on loading the drums, winding it up, and charging the feed tower? I just ordered all the stuff and would love to see how it is all done. thanks!

 

[rgvwheeler]

I bought 2-165 round drums and realized I only had enough dummy rounds to load one. Is it ok to load the drums without the dummy rounds?

 

[dnh]

Yes, I load them full of real ammo with no dummy rounds, and it works the same. I just don't like keeping track of the dummy rounds in addition to everything else that goes with using the drums.
