Converting Rem 700 Magazine for 6BR
by Mike Bryant
Shown below are step by step photos of blocking a .308 Rem 700 magazine to allow the shorter 6BR (6mm BR Norma) to feed out of a Remington 700 action. I’ve done this conversion many times and it works well. The only magazine that I’ve done like this that wouldn’t feed was for a .20 BR which is shorter than the 6mm BR. The .20 BR needed a longer magazine block. I figure the block from a .221 Fireball and .221 Fireball mag spring would have worked on it. –Mike Bryant, BryantCustom.com

|The rear of the .308 magazine has been cut with a Dremel cut
off wheel to make ears similar to those used on a .223 magazine to
hold the magazine block (the metal spacer at the rear of the mag, visible in top photo).
|Here is a photo of the .308 magazine with the ears bent over.|
|This shows the .308 magazine with the block from the .223 magazine in place.|
|We cut the rear of a .308 follower to fit in the blocked .308 magazine. The rear of the follower is also beveled to allow the bolt to close without having to push the follower down.|
|Here is the finished modified .308 follower in place in the blocked magazine.
A magazine spring from a .223 magazine is used instead of the .308 spring.
