Default Help Identify Manufacturer of M14 Piston

The piston is marked BKFLD. PREC. IL with a R in circle. It the piston area is TiN coated and the shaft is not coated. There are 6 grooves forward of the gas hole and one to the rear. The hole is the same size as other M14 pistons. I suspect that this is a Brookfield but have never seen one and can't find a decent picture of the markings.

Thanks for your help.

It is a Brookfield Precision. The guys building XM25 clones seek those out IIRC.

Thanks for the info. I wasn't positive about the manufacturer.

As others noted, its a BPT. (seen in the middle of this pic). The Sadlack is fully coated, and the SEI is chrome plated and
probably the highest quality gas piston available, but for old-school XM25/M25 projects the BPT is the preferred part.
(Piston the far right has nitrated finish)



Paul, if you don't have a specific need for it, and if its in excellent condition, I would be happy to buy or trade you
for another gas piston as I'm working on piecing together an XM25 replica and I'd like to have a spare BPT piston...
Here's my project parts to date for a late 1980's era 'old school' XM25 replica:
