I want to start shooting NRA High power service rifle so I built a lower and ordered an upper from White Oak Armament but because I live in New York the only magazines I can get is 10 rounds I have not been able to find Pre Ban 20 round ones locally, will the 10-round be legal to shoot in competition?
Thanks in advance

I have 2 of these that I use for service rifle, they're good mags.

http://www.bushmaster.com/electronic-documents/2006CatalogV2/p36-39Magazines.pdf

The above link states "legal for Service Rifle Competition"( for the 30-452)
They are the same external dimensions as a 20 rd GI mag.

Get 20rd GI mags. They were made before the ban and are legal in NY. You should be able to get them at the gun shows or in the free states.

CMP Rules Section 6.2.3 U.S. Rifle, Caliber 5.56mm, M16 .....
....."A 10-round magazine with the same external dimensions as a standard service 20-round box magazine may be used...."

I didn't see a note to allow the 10 length magazine, just the straight 20 or curved 30. Maybe take a look at the rule books, thay are posted on the web in PDF and you can run the search tool to find all the instances of the word magazine.

C-Products makes a 10 rounder that has the same external dimensions as a GI 20 rounder. Never had a problem with them. Seem to work great.

Don't know about the 10 rounders, but my 20 rd C-products mag failed to hold the bolt open (new out of the package).  I changed the followers with Brownells green 30 rd anti tip and they are 100% now.

Interesting. I have not had any problems, but then again I'm only loading 8 at a time.

I was loading 2 & 8..  Mag change also involved pulling the charge handle to load.

I used the aluminum NH(whatever al the letters are) mags til I found out about the followers.

I like the SS mags beause the weight helps them fall when released.

I've used the Bushmaster 10 rounders for years in CMP matches.  Never had any trouble at all.

Thanks for all the responses I will order the bushmaster mags and keep my eyes open for the GI 20 rounders.

The only places you might get dinged on it might be a regional or state match. Besides that no would care. The first year i shot my ar with a 40rd since it only came with two blocked 20 round mag to 5 rnds. I just got looks and that was it.

I was able to find 20rd and 30rd look at some the local gun shops also you should be able to land a preban mag or two.

Try Golden State Tactical. We in Cali have the same restriction and the 10/20 and 10/30 mags are pretty much all we use here (mainly the 10/20's) since they're both state and CMP legal.

tom 2009- where in  NY are you? I have a good supply of 20 orunders  and I could certainly let go of two for a new high power shooter starting out- I would not charge you some scaplper pre ban price either
