I have an FN SPR built in a Manners T4 and have been using a PTG bottom metal with AE MK1 mags for a couple years.

The AE mags are only made in 5rnd capacity. Since i plan on shooting some PRS matches next year, i decided to switch over to something that uses 10rnd mags.

I found a smokin deal on ebay and picked up a new-in-box TBM kit for 150$.

I just finished up making new pillars, milling the inlet and bedding it a few days ago, and took it to the range for the first time yesterday.

Holy crap it feeds easy. I didnt know a CRF gun could feed this smoothly!

Anyone elses using a TBM? How do you like it?

I'll be getting one and a new stock for my PBR XP. Sounds encouraging.
