Looking at the thread up to this point, it looks like we are a chunk away from even the 100. Any price update? I would like to get 1.

I've updated the original post with pricing information for 50 pistons. I've also extended the end date with the hope we can boost these numbers up a bit. I appreciate everyone's support and hope we can get the commitment numbers higher or this will need to be shelved for the time being.

This is a group buy for the P7M series pistons only (not the PSP, or P7K3 series) - if successful, I plan to offer the PSP piston as well, but that will be at a later date.

I’ve reverse engineered the piston based off a few P7M8’s I personally own as well as the specs relayed from the armorer's manual and have engaged with a machine shop that does both precision turning as well as grinding to meet the tight tolerances required of the gas rings on the piston. As a result, I’m offering a group buy with minimum quantity to get this started at a minimum order quantity of 50 - the pricing tiers break down as follows:

50 pistons - $180 each
100 pistons - $100 each
200 pistons - $80 each
300 pistons - $60 each

So long as we're close (<10 away), I'll purchase enough to bump us to the next tier.

I plan to leave the group buy open until June 15th - payment in full will be due by then. I accept PayPal ([email protected]), Venmo (@Steven-Walker-20), and ApplePay. I can also accept MO but will require they are postmarked by June 5th in order to allow time to receive and deposit the funds - PM for address details. The lead time to produce the items upon order placement is 14 weeks. During that time I will also procure the spring pin, have the detent spring manufactured, and piston detent manufactured required the complete the gas piston sub-assembly and include in the price above for group buyers (I also have the gas piston retaining roll pin that keeps it in the slide available as well if this part has been lost or damaged for an additional $5). After the group buy I plan to have these available at $140 as the cost of the piston is very high due to the extremely tight tolerances for the gas piston area. The pistons will come fully assembly and ready to put in your pistol - no need to assemble the detent assembly.

I’ve also asked James with Teufelshund Tactical @Marine0303 to inspect the first part using his armorer go/no gauges to guarantee function before moving forward with the remaining parts so we all get fully spec’d parts with no surprises.

If this is successful, I plan to continue to increase the number of parts available so we can all continue to enjoy our P7’s without the worry that eventually we won’t be able to replace routine maintenance parts and do what you’re supposed to do with HK’s - shoot them regularly!

Best,
Brett
