Adams arms low pro pistol length piston is legit. - Adams Arms P Series Micro Block Pistol Length Piston Kit

Low profile block was sleek and fit under rail nicely. Worked out as expected. Recommend. The piston system all worked out as planned as well. Wish they had the low mass BCG in stock but no big deal. I’ll try this set up out and upgrade from here. Other than that I just need to get to the range and try everything out.
